The four study scenarios are: Case 1 -An 8 million ton per year Beluga mine. Case 2 -A 12 million ton per year Beluga mine. Case 3 -An incremental 2 million ton per year Nenana study which would expand a hypothetical existing mine from 2 million to 4 million tons per year. Case 4 - A 3 million ton per year Nenana mine with a staged build up in million ton per year increments. .- - - PAUL WEIR COMPANY For each of these four cases,the study is to estimate the capital and operating costs in constant January,1985 dollars.From these costs, the f.o.b.mine price is calculated which will provide an appropriate return on investment • This "Introduction"is followed by a "Summary"section which pre- sents the most pertinent study results.The remainder of the report deals in detail with the geology,mine plans,cost estimates and pricing. 2. ..... PAUL WEIR COMPANY 11.SUMMARY Detailed discussions of the procedures,assumptions and results of the studies are presented in subsequent sections of this report.A sum- mary of the most pertinent results is shown on Table No.1 (immediately following). For the two Beluga studies (Cases 1 and 2),the stripping ratio shows a slight increase from 6.7 to 6.9 as the production level increases from 8 to 12 million tons per year.This is a result of mining more of the deeper coal to satisfy the increased total coal requirements.The effect of this increase is reflected in the reduction from 46 to 44 tons per man- shift.This Seems to indicate that the economy of scale effect is,at best, very slight at these production levels.The capital investment per annual ton and average production cost figures echo this indication. The Nenana studies (Cases 3 and 4)have nearly identical stripping ratios because the total coal tonnage requi~ements are very similar.Compar- ison of these two studies is difficult because of the differences in the scenarios.Case 3 is based on an incremental doubling of the production of an existing mine,while Case 4 is all new production with a completely different production build up schedule.These differences are illustrated by the fact that,although Case 4 has a higher labor efficiency at full production (43 versus 40 tons per manshift),it also shows a slightly higher average operating and maintenance cost ($13.76 versus $13.12 per ton). 3.

The net result is an indication that coal mined in the Beluga area can be quite competitive on a local or export market,particularly at the high production levels studied.Smaller mines,of less than 3 or 4 million tons per year,would need to be located in very low ratio (less than 3 to 1)areas to be competitive.Such areas very likely do exist, but,in our opinion,are not typical of the conditions one could expect to encounter during the 50 year life span of the Susitna Project • .The Nenana area coals will be somewhat more expensive to mine at the production levels studied,but should be able to compete on a fairly local market.The distance from tidewater is a negative factor for the Nenana area when competing with the Beluga coal for export sales. 5. f . ".." PAUL WEIR COMPANY III.GEOLOGIC MODELS Most of the information presented in the following discussion was obtained from the publication,"Surface Coal Mining in Alaska:An In- vestigation of the Surface Mining Control and Reclamation Act of 1977 in Relation to Alaskan Conditions."This document was compiled from many sources by the: Committee on Alaskan Coal Mining and Reclamation Board on Mineral and Energy Resources Commission on Natural Resources National Research Council National Academy of Sciences It was published in 1980 by the National Academy Press,Washington,D.C. This source will be referred to as the National Research Council throughout this discussion. Beluga Area The Beluga area is located in the Susitna Coal Field in south- central Alaska,approximately 50 miles west of Anchorage.The coal resour- ces of the Susitna field are comprised of the Yentna area in the north and the Beluga area in the south.Both areas contain multiple seams of low sulfur,lignite-to-subbituminous coal.Coal thicknesses run from less than 6 feet to 50 feet.Overburden and innerburden lithologies range from mass- ive sandstone and conglomerate to poorly consolidated shales,siltstones 6. PAUL WEIR COMPANY and claystones.The strata are generally gently-to-moderately dipping, although some folding and faulting have occurred,resulting in locally steep dips in some areas.Bedrock is typically overlain by glacial till and mus- keg.Topographic relief is moderately rolling,with some areas of steeply incised streams and rivers.Vegetation ranges from grasses and scrub brush in the upper elevations to dense stands of evergreens at lower elevations. The National Research Council has listed the Indicated and Inferred resour- ces for the Susitna field at 2.7 to 10.2 billion tons.Hypothetical resour- ces are listed at 27 billion tons. The hypothetical Beluga deposit selected for this study contains three minable seams of subbituminous coal designated:L,M and U (for Lower, Middle and Upper).The seams are separated and/or overlain by poorly consol- idated shales,sandstones and siltstones.The surface material consists of varying thicknesses (0 to 40 feet)of glacial till,which is overlain by muskeg.The coal seams dip at 3 to 10 degrees,with an average of approx- imately 5 degrees (8 percent).The Lower Seam thickness ranges from 23 to 38 feet,averaging 26 feet.This seam contains partings of variable thickness which must be removed to preserve the quality of the product. The Middle Seam averages 28 feet in thickness (range 21 to 35 feet)and lies 225 to 325 feet above the Lower Seam.The Upper Seam lies 275 feet above the Middle Seam and averages 18.5 feet thick (range 12 to 24 feet). The deposit is assumed to be broken into two distinct areas (A and B)by an erosional feature which separates the two areas by approximately 8,000 feet. ~' PAUL WEIR COMPANY Area A is the larger area,covering approximately 5,000 acres between the Lower subcrop and the 400 foot cover line on the Upper Seam. Total in-place coal in this area is 250 million tons.Area B covers 3,500 acres and contains 160 million tons in-place.A typical dip-oriented cross section representing the two areas of the deposit is shown in Figure 1. Coal quality is somewhat variable from seam to seam and laterally within each seam.The Lower Seam is assumed to be uniformly lower in quality than the Middle and Upper Seams.The average run-of-mine heating value,including allowance for dilution,is assumed to be 7,500 Btu/lb. Nenana Area The Nenana coal basin includes the Healy Creek,Lignite Creek, Jarvis Creek,Wood River,Tatlanika and Teklanic fields.It is located in an area about 200 miles north of Anchorage and 60 miles south of Fair- banks.Alaska's only current significant coal production comes from the Nenana area in the Lignite Creek field.The Nenana resources are contained in multiple seams of low sulfur,subbituminous coal.Seam thicknesses range from 2.5 to 60 feet.The coal bearing strata are comprised of moderately consolidated sandstones and siltstones which have been folded and faulted to form the subbasins referred to above.Discontinuous occurrences of perma- frost are present in ~he area.The attitude of the beds ranges from flat at the axes of the synclines and anticlines to steeply dipping on the flanks of the folds.The surface material is composed of weathered bedrock with peaty layers at the immediate surface and alluvial deposits in the stream 8. :C, ( 1..- '"'"I PAUL WEIR COMPANY beds.The topography is quite rugged in the vicinity of the streams and moderately steep-to-gently rolling on the upland areas between the water- courses.Vegetation ranges from spruce and hardwood forest to barren ground with some areas of tundra. The National Research Council lists the resources of the Nenana field at 3.5 billion tons of Proven coal plus 3.5 billion tons of Inferred coal.Total potential is listed at about 15 billion tons. The hypothetical Nenana deposit selected for this study contains three minable seams designated:B.I and T (Bottom.Intermediate and Top). The seams occur within an area of lightly indurated sandstones and moderate- ly consolidated siltstones.All three seams outcrop along a valley and dip into the valley wall at 8 to 13 degrees (averaging 10 degrees).The deposit consists of two areas (X and Y)separated laterally by approximately 10.000 feet of noncoal bearing area. In Area X.the Bottom Seam averages 20 feet in thickness.the Intermediate Seam 30 feet.and the Top Seam 22 feet.The Bottom-Intermed- iate Seam interval is 75 feet.and the Intermediate-Top Seam interval is 140 feet.The total area between the Bottom outcrop and 300 feet depth on the Top Seam covers 850 acres and contains approximately 44 million tons in-place. 9. """ ..." .... PAUL WEIR COMPANY Area Y contains the same seams,with average thicknesses being: Bottom Seam 18 feet,Intermediate Seam 30 feet,and Top Seam 15 feet.The average interval thicknesses are:Bottom-Intermediate 90 feet and Intermedi- ate-Top 120 feet.Area Y covers 900 coal bearing acres and contains 35 million tons of coal in-place. Figure 2 shows a typical cross section of each area of the hypo- thetical Nenana deposit. Coal quality is assumed to be somewhat variable but poses no spec- ial blending problems.The run-of-mine heating value is assumed to be 7,600 Btu/lb.for Case 3 reserves and 8,100 Btu/lb.for Case 4 reserves.These values were provided by H-E. 10. ( ......... ( ,-" -- !""" i i PAUL WEIR COMPANY IV.MINE PLANNING Selection of Mining Method The following surface mining methods were considered for each of the cases: 1.Bucket-wheel excavators (BWE's)and conveyor transport. 2.Shovel-truck (or loade~-truck)stripping on the upper levels with a dragline on the bottom waste benches. 3.All shovel-truck (or loader-truck)stripping. All of these methods present advantages and disadvantages and involve some risks.Following is a brief discussion of these advantages and risks for each'method: 1.BWE's,combined with conveyors to transport the materials,offe~ high productivities and low operating costs in the appropriate application.They do not require large quantities of petroleum products,which may be an advantage if the petroleum market becomes very strong. 11. PAUL WEIR COMPANY Capital requirements are high for this type system.Technical risks in this application are the possible presence of boulders or indurated strata in the overburden;which could cause vibra- tion and breakdown to the BWE system,and the wet sticky nature of the overburden which could cause handling problems (particularly during the winter)in the buckets,on the conveyors,and in the transfer chutes.BWE/conveyor systems are relatively inflexible and present problems when changing short-term operational plans. Historically,BWE/conveyor systems have exhibited low mechanical availabilities (50 to 55 percent). 2.Draglines could be applied to the bottom 100 to 125 feet of the overburden.Draglines offer comparatively low operating costs per unit of production and have demonstrated high mechanical avail- abilities.Petroleum product consumption is low for these mach- ines.The use of shovels (or loaders)and trucks ahead of the dragline would provide some flexibility in dealing with short-term changes in mining plans and production requirements. The initial capital requirements are quite high for draglines per unit of ~roduction.Electrical peak loads are very high com- pared to shovels or B~~'s.Technical risks revolve primarily around the impacts of geotechnical and hydrological considerations on slope stability.Flat highwall and spoil slopes will require added rehandling and reduce the dragline's efficiency. 12. PAUL WEIR COMPANY - 3.Shovel-truck (or loader-truck)systems have been thoroughly proven throughout the world's mining industry as reliable producers. Initial capital requirements are low relative to BWE's or drag- lines.The flexibility of a shovel-truck system is extremely high.Peak electrical requirements are fairly low. These systems are more labor-intensive than the other systems, which compounds the exposure to labor cost increases or labor relations problems.Trucks are heavy consumers of diesel fuel. The only significant technical risk in this type system is the potentially high cost of haul road construction due to relatively soft ground conditions and high precipitation levels. In making a coal pricing study,as in a feasibility study,it ( is very important that the system chosen be technically sound and proven in similar applications.The BWE/conveyor system was rejected because of the uncertainty that the system could effectively dig and convey the mater- ials present in the Beluga and Nenana areas.Therefore,for each case stud- ied,only dragline and shovel-truck (or loader-truck)methods were applied. 13. """'I i I 1'"'"' I PAUL WEIR COMPANY Mining Plans Case 1 (8 Million Tons Per Year -Beluga) The mining method selected for this case is a combination of shov- el-truck plus dragline stripping.The draglines are assigned to strip all material overlying the bottom seam being mined up to a maximum depth of 125 feet.The draglines selected can swing 70 cubic yard buckets at an operating radius of 300 feet.Figure 3 shows a range diagram of the drag- - line operation at the maximum depth.The shovel-truck fleet is used to remove all other overburden and innerburden in advance of the draglines. The project area is Area A.This area contains enough reserves for the project life and offers the opportunity to have several long drag- line pits for efficiency in scheduling. The area was subdivided into several pits and further broken down into 600 foot wide strips.These strips represent five cuts 120 feet wide. The quantities of coal,overburden,innerburden and parting were calculated for each strip.Each seam was measured to a maximum depth of 400 feet. When the bottom seam reaches this depth,the dragline will "jump"up and continue stripping the next higher seam. Initial stripping begins near the Lower Seam cropline in the west- ern portion of the deposit (see Exhibit A).The first dragline opens up 14. ...... ~, - PAUL WEIR COMPANY the area near the cropline,while a shovel-truck fleet begins prestripping those areas in advance of the dragline where the cover is greater than 125 feet.This sequence continues until the third year of production when the second dragline begins stripping in the eastern portion of Area A.There- after,the two draglines advance downdip (northerly),with shovel-truck stripping at least 1 year in advance. Due to the high volume of production (8 million tons per year), it is assumed that this will be a multicontract mine.Therefore,the prob- lem of low quality in the Lower Seam may be partially handled by setting lower quality limits in some of the coal sales contracts.As the mine is fully developed,there will be natural blending of the three seams,and the average run-of-mine quality is assumed to be 7,500 Btu/lb. The mining operation was sequenced in annual increments for the first 15 years and in 5 year blocks thereafter. Major equipment items for Case 1 include: Item Overburden Draglines Overburden Shovels Coal Loaders (Hydraulic) Overburden Haulers (Rear Dump) Coal Haulers (Rear Dump) Graders Dozers Scrapers Size 70 Cubic Yard 20 Cubic Yard 18.5 Cubic Yard 120 Ton 120 Ton 16 Foot Blade 300 and 400 Horsepower 31 Cubic Yard,Twin Engine 1 5. ,.,.. 'f"'"' i "'... PAUL WEIR COMPANY Case 2 (12 Million Tons Per Year -Beluga) The mining plan for this case is quite similar to that chosen for Case 1.Stripping is to be done by draglines at depths up to 125 feet over the lowest seam being mined.Shovels and trucks strip all other mater- ial in advance of the draglines.The draglines chosen are one 70 cubic yard model plus one 110 cubic yard machine.Both draglines have an operat- ing radius of 300 feet.The range diagram shown in Figure 3 is represent a- tive of Case 2,as well as Case 1. The size of this project dictates the use of both Area A and Area B to satisfy the total reserve requirements. Both areas were subdivided into pits and strips similar to Case 1 and quantities determined for each strip.Maximum depth of mining is again 400 feet. The operation begins with the 110 cubic yard dragline stripping at the Lower Seam cropline in the western portion of Area A.By the second half of the second year,it is necessary to bring the 70 cubic yard draglinc into Area B and begin uncovering the Lower Seam near the crop.Exhibit B shows the advance of the draglines throughout the project life.The shov- el-truck fleets maintain advance stripping at least 1 year ahead of the draglines. 16. ..- PAUL WEIR COMPANY As in Case 1,the coal quality averages 7,500 Btu/lb.,as-mined. The sequencing calculations were done annually for the first 10 years and in 5 year blocks thereafter. Major items of equipment for Case 2 include: ..... Item Overburden Draglines Overburden Shovels Coal Loaders (Hydraulic) Overburden Haulers (Rear Dump) Coal Haulers (Rear Dump) Graders Dozers Scrapers Size One 70 Cubic Yard and One 110 Cubic Yard 20 Cubic Yard 18.5 Cubic Yard 120 Ton 120 Ton 16 Foot Blade 300 and 400 Horsepower 31 Cubic Yard,Twin Engine 17. '~. - PAUL WEIR COMPANY Case 3 (2 Million Tons Per Year-Incremental -Nenana) The combination of dragline plus loaders and trucks was chosen for this case.All overburden and innerburden must be drilled and blasted prior to stripping.Front-end loaders and trucks remove the upper overburden and innerburden zones ahead of the dragline.The dragline will strip the Bottom Seam in the simple sidecasting mode.As the Intermediate Seam is encountered,the dragline will strip up to 60 feet of cover on the Inter- mediate Seam and then move down on the Bottom Seam innerhurden and strip that seam.This will involve some extended bench rehandling,as shown in Figure 4.After reaching the 300 foot depth on the Bottom Seam,that seam will be abandoned,and the dragline will strip the Intermediate Seam (and eventually the Top Seam)in a single seam operation to a maximum of 100 feet of cover.The dragline will carry a 30 cubic yard bucket and have a 300 foot operating radius. The project area is Area X of the Nenana hypothetical deposit. This area contains sufficient reserves at an attractive stripping ratio. It is also closer to the assumed coal delivery point than Area Y,thus short- ening haulage cycles,as well as haul road and power line construction. The area was subdivided into four pit areas ..Two hundred foot wide strips (two 100 foot dragline cuts)were laid out in the areas amenable to dragline stripping.In the other areas,400 foot square blocks were laid out for loader-truck mining.The quantities of coal,overburden,inner- 18. .... -c ..... .... PAUL WEIR COMPANY burden and parting were calculated from each area.Maximum mining depth was set at 300 feet. Initial stripping begins with the dragline making a box cut at the Bottom Seam cropline in the eastern portion of the area.By the third year of production,the loader-truck fleet begins operation in the central part of Area X and commences prestripping ahead of the dragline in the east- ern portion.The sequence continues until the tenth year,when the dragline moves over to the Bottom Seam cropline in the western portion of the area and strips downdip through the remaining project life.The sequence is shown on Exhibit C.The loader-truck operations are maintained approximate- ly 1 year in advance of the dragline stripping.Average run-of-mine quality is assumed to be 7,600 Btu/lb • The mining sequence was computed in annual increments for the first 10 years and in 5 year blocks for the next 10 years. Major equipment items for Case 3 include: - Item Overburden Dragline Overburden Drills Overburden Loaders (Front-End Loaders) Coal Loaders (Front-End Loaders) Overburden Haulers (Rear Dump) Coal Haulers (Rear Dump) Graders Dozers Scrapers Size 30 Cubic Yard 10 Inch Diameter 13 Cubic Yard 13 Cubic Yard 85 Ton 85 Ton 16 Foot Blade 300 and 400 Horsepower 31 Cubic Yard.Twin Engine 19. -, PAUL \VEIR COMPANY Case 4 (3 Million Tons Per Year-Staged Increase -Nenana) This case is mined in a similar manner as Case 3.Front-end load- ers and trucks strip in advance of the 30 cubic yard dragline.The tonnage requirements necessitate utilizing both Area X and Area Y for this study. The dragline range diagram for the Area Y operations is shown in Figure 5.It is similar to that for Area X,except that the greater thickness of the Bottom Seam innerburden involves more rehandle in the extended bench mode.Overburden and innerburden are drilled and blasted in this case also. "The pit layout for Area X is identical to that used in Case 3. In Area Y,200 foot wide strips were laid out for four pits,and the coal and waste quantities were calculated for each strip. The operation begins in the eastern portion of Area Y,with the dragline box cut on the Bottom Seam.Loader-truck prestripping begins in the second year and continues about 1 year in advance of the dragline. By year 7,the dragline moves to the western portion of Area Y and finishes stripping there in year 13.Then,it is moved to the eastern part of Area X and finally finishes up in the western part.Exhibit D shows the strip- ping sequence for Case 4. The production level begins at 1 million tons per year,increases to 2 million tons in the third year,and goes to )million tons in the ninth year of production.The average heating value is assumed to 8,100 Btu/lb., as mined. 20. ,-. :~ I ~iill I ' PAUL 'WEIR COMPANY The list of major equipment items is identical to that for Case 3. 21. ! '- ,.... - PAUL WEIR COMPANY Equipment Selection SelectiOn of the major excavation equipment such as draglines, shovels and trucks was based on the volumes of overburden to be stripped and the tonnage to be produced.Initial estimates were made and later revised as the mining sequence was worked out.Other items of equipment were selected to be compatible with the major equipment items and,also,whenever appropri- ate,to be common to all the cases studied.Tables No.2 A through No.2 D list the equipment items selected for the four cases studied.(~:All Tables,with the exception of Table No.1,are found in the back of this re- port.)The equipment models listed are intended to identify a typical size of equipment which is widely known.No endorsement of this equipment is im- plied since other similar models could be used. Major equipment items for Case 1,the 8 million ton per year Beluga case,consisted of 70 cubic yard draglines and 20 cubic yard shovels for over- burden stripping and 18.5 cubic yard hydraulic front shovels for coal loading. Overburden and coal were hauled in 120 ton rear dump trucks.The coal trucks had oversized bodies to carry the less dense coal. Major supporting equipment used consisted of large crawl~r dozers for reclamation,stripping,coal loading and construction work;smaller crawler dozers to assist the draglines and gravel plant;coal drills for coal shooting; scrapers for reclamation and construction work;and graders,water trucks and wheel dozers for road maintenance. 22. r ( c..... r I (' PAUL 'WEIR COMPANY Productivity Estimates Projections of the amount of work that the various major items of equipment could perform were made for the differing conditions and equipment mixes that occurred in each mining case.Examples of productivity calculations are appended to this report,and a description of particular productivities used in Case 1 follows. Basic productivity of the draglines was estimated dependent on ma- chine geometry.This basic productivity was adjusted to give effective produc- tivities dependent on the cut geometry and rehandle requirements.In Case 1,a dragline with a nominal 70 cubic yard bucket was estimated to have a basic productivity index of 255,000 bank cubic yards per year per cubic yard of bucket capacity.The nominal productivity was 17,850 bank cubic yards per shift for 1,000 scheduled shifts per year.Digging in a 120 foot wide pit and excavating 125 feet of material from a bench 80 feet above the coal, a projected 46 percent of the material would have to be rehandled.Effective productivity was therefore 12,250 bank cubic yards per shift scheduled.The 6,125,000 bank cubic yards of overburden removed in the first year of coal production in Case 1 required 500 dragline shifts. Shovel and loader productivities in overburden st.ripping,coal load- ing and parting removal were estimated based on the size of the machine and the size of the truck it was loading.The loading equipment was projected to operate at the average productivity estimated.Enough haul trucks were 23. \.--~ -~ PAUL WEIR COMPANY scheduled on each load center haul to keep the loaders operating.In Case 1,the 20 cubic yard shovel loading overburden into 120 ton trucks was estimat- ed to have an average productivity of 5,536 bank cubic yards per shift sched- uled.In the first year of coal production,3,272,000 bank cubic yards of overburden were hauled an average of 4,000 feet to a waste dump.The number of shovel shifts required to load this amount of material was 592.The number of truck shifts required to maintain the utilization rate of the shovel was 1,895. Similarly,the 18.5 cubic yard,hydraulic front shovel loading coal into 120 ton haul trucks had an estimated productivity of 6,361.6 tons per shift scheduled.In the first year of coal production,2,500,000 tons of coal were loaded in 394 shifts.The coal was hauled from two different load centers an average of 6,820 feet and 8,120 feet to the coal handling hopper. A total of 1,290 truck shifts was required to maintain the utilization rate of the shove 1. Overburden drilling,when required,and coal drilling productivitics were estimated from an assumed drilling pattern,bench height and material drillability.In the first year of coal production in Case 1,a dual mast. auger type coal drill was estimated to have productivity of 20,650 tons of coal drilled per shift.A total of 122 drill shifts were scheduled to drill the 2,500,000 tons of coal shot. 24. ,. \".,. ,.... PAUL WEIR COMPANY Scraper productivity was estimated based on an assumed haul distance and on the kind of work performed,i.e.,removing overburden and parting, constructing roads,etc. 2 s. .- PAUL WEIR COMPANY Units of Work The overburden removal and coal production sequences determine the rest of the work which must be accomplished.After the mining sequence is plotted on maps and the locations of centers of mass of overburden removal are plotted,locations of spoil piles are determined.Dragline yardage is spoiled into adjacent cuts,but shovel-truck yardage must be dumped where it won't interfere with subsequent operations and will facilitate reclamation of the mined area.In most cases,initial shovel-truck spoil was dumped out- side the mined area in surface dumps and only backfilled over the top of drag- line spoils as the mining operation progressed. Haul roads were laid out from the centers of mass of overburden and coal removal to the centers of mass of spoil placement or coal dumping. Average haul distances were measured and estimates of truck speeds were made dependent on the haul profiles. If the coal seam contained removable partings,quantities were esti- mated and dumping locations were projected depending on the sequence of coal removal.Partings could be handled by dozing short distances in the pit, by scrapers hauling intermediate distances,or by trucks 'hauling to spoil dump s • Coal and overburden drilling and blasting requirements were match- ed to the quantities produced by the mining sequence. 26. /~ PAUL WEIR COMPANY After the haul roads were laid out for the life-of-mine plans,se- quences of construction and maintenance were developed. Finally,reclamation plans were developed summarizing when areas would be disturbed prior to mining and when areas would be reclaimed.Gen- eralized surface water control structure requirements were esti~ated. The various measures of work required were used as input parameters for calculating the equipment and manpower requirements.The work was separat- ed into the following mining functions: c •Drainage Control and Reclamation An average depth of 1 foot of surface material (topsoil or root medium)was removed by scrapers from the areas projected to be disturbed each period.This material was either replaced on re- graded areas or hauled to stockpiles for later replacement if enough regraded area was not available. Drainage control structures -perimeter ditches and dams for sedi- mentation ponds -were constructed by scrapers. Rainfall,based on the annual average,was collected in the unre- claimed pits and",together with an equal volume of groundwater, was pumped out of the pits into the sedimentation ponds. 27. PAUL WEIR COMPANY Revegetation supplies and equipment were scheduled following the topsoil replacement.Final post mining reclamation was not includ- ed in these operating costs,but was treated as a post operating capital charge. •Overburden Stripping Overburden removed by draglines was scheduled according to the productivities estimated for the draglines in the various digging modes. Drilling and blasting requirements were estimated from the in- place overburden quantities to be removed according to the mine plans. Overburden removed by shovels or loaders and hauled by trucks was scheduled by the quantity located at each haulage load center. Separate calculations of overburden drilling and blasting require- ments,excavator shift requirements,and overburden haulage pro- ductivities based on average cycle times were made. Equipment shifts were scheduled for grading spoil piles where necessary prior to reclamation. 28. PAUL WEIR COMPANY • • Mining and Hauling Coal Coal production was scheduled by the quantity located at each haulage load center.Separate calculations of coal drilling and blasting requirements,excavator shift requirements,and coal haulage productivities based on average cycle times were made. If removable partings were present in the coal seam,equipment was scheduled to remove it based on estimated distances to part- ing dump sites.Dozers,scrapers or loaders and trucks could be used. Coal Handling Run-of-mine coal was dumped into a receiving hopper in the mine facilities area.The coal was crushed to a 6 inch topsize for the Beluga area mines and discharged onto a conveyor belt for delivery either to a nearby power plant or to a more distant port. Coal handling costs chargeable to the mining operation stopped at the crusher discharge point.At the Nenana area mines,the coal was crushed to a 2 inch topsize and conveyed to a covered storage building with unit train loadout facilities.Coal hand- ling costs chargeable to the mining operation included discharg- ing the coal into rail cars. PAUL WEIR COHPANY .... - r- '~ •Haul Road Construction and Maintenance Two different generalized haul road designs were made for the four cases.A heavy duty road was used in Cases 1 and 2 to support intense traffic by the 120 ton trucks.A light duty road was used Cases 3 and 4 to support traffic by the8S ton trucks.The de~scriptions "heavy and light"are relative terms in this context. Road base material was obtained from a mine-operated,gravel screen plant.A source of gravel was assumed to be located within 5 miles of the point of use. Haul roads were constructed according to the mining schedule, and the length of road in use each year was maintained by a fleet of graders,water trucks and wheel dozers. "- '--" •General Mine Services The summation of shifts worked by operating and maintenance person- nel in each of the various pay grades in all the mining functions was used as a base to determine the number of people required to run the mine.An allowance was made for absenteeism of S per- cent of the required shifts for the Beluga area mines and for 3 percent for the Nenana area mines.A work year of 250 man-days was used as a base to determine the number of people required. Extra manshifts were allocated to each pay grade in this function to make full multiples of 250 man-days [or all work required. 30. "'; ~---~ - r-~'~"III '- PAUL WEIR COMPANY A general labor crew and construction and custodial manpower were assigned to this function. An operating supplies allowance based on the size of the workforce was assigned to this function to cover the cost of miscellaneous equipment operation and repairs. •Supervision and Administration A supervisory and administrative table of organization was pre- pared for each mining case.The number of people required depend- ed on the number of wage employees and on the mining activities. The mine was expected to be a self-sufficient operation with the primary exception of legal and marketing personnel. The operation was assumed to be part of a larger company and was charged a general and administrative overhead allocation equal to 4.5 ~ercent of the average annual mine operating cost plus the average capital cost. •Production Taxes and Fees The Federal abandoned mine land reclamation fee of $0.35 per ton and the Black Lung Tax at a rate of $0.50 per ton are included in this function. 31. -- -c PAUL WEIR COMPANY V.COST ESTIMATES Operating Costs All costs are estimated in January,1985 dollars.Labor rates are based on the labor agreement at the Usibelli coal mine near Healy,Alas- ka.Hourly rated personnel are separated into five pay grades based on the classifications in that agreement.Direct wages and salaries used in all the case studies are as follows: Labor overhead costs (fringe benefits,payroll taxes,etc.) were unifornlly estimated to be 40 percent of direct wages and salaries. Diesel fuel was estimated to cost $0.88 per gallon delivered at the minesite for the Beluga area mines and $0.95 per gallon delivered at the minesite for the Nenana area mines. 32. - ...,. PAUL WEIR COMPANY Explosives costs for coal shooting at the Beluga area mines and for overburden and coal shooting at the Nenana area mines was esti- mated to cost $375 per ton delivered in bulk to the minesites. Electric power costs were estimated from expected average demand and usage requirements for the mines as a whole.Electric power rates were provided by H-E and were based on the rates charged in the Chugatch Electric-Whittier District.The rates used are: Demand:$6.06 per month per KW demand Energy:First 100 KWH @ $0.082 per KWH Next 200 KWH @ $0.066 per KWH Allover 200 KWH @ $0.041 per KWH Combining the demand and usage costs resulted in an effective rate of $0.053 per KWH in the Beluga area.Costs were estimated to be $0.106 per KWH in the Nenana area,reflecting the higher rates in the Fairbanks-Tanana area. The costs of repair parts and operating supplies and of fuel and lubricants were estimated for the major equipment items used in each mine plan.Maintenance labor requirements per shift operated were also estimated.Productivity estimates for the major excavating machinery (draglines and shovels)were based on estimates of availability.Other major items of equipment were scheduled to operate a maximum number of shifts per year based on estimated availabilities. 33. /,- - - r: -- ~. i PAUL WEIR COMPANY SUG~aries of the operating costs and shifts for the major equipment items are presented in Tables No.2 A through No.2 D for the four mine stu- dies. The units of work in each mining function calculated from the mining plans,as di:!scribed in the "Mining Plans"section of this report,are combined with estimated machine and labor productivities to generate the equipment shifts required to do the work during each period of production.The equipment shifts in turn were combined with labor and other unit costs to generate esti- mated operating costs. Tables No.3 A through No.3 D present,for the four cases,the estimated operating costs by mining function for each period of production. The timing of the mine studies generally reflects a 7 year period leading up to the statrt of production in year 8 (year 6 for Case 3).Feasibility assessment of a previously explored property and engineering and permitting activities are estimated to take 4 years.Minesite construction and preproduc- tion operations take J years (2 years for Case 3). Basic units of work (i.e.,area disturbed,overburden volume,coal produced,etc.)and the major equipment item operating shifts required to do the work are shown for most mining functions. 34. ..... PAUL WEIR COMPANY Annual summaries of the operating costs separated into cost compon- ents (labor,supplies,fuel,etc.),annual manpower requirements by pay grade and annual equipment shifts operated are presented in the last pages of these tables. Some costs such as the Federal Black Lung Tax and an allocation of general and administrative expenses of the hypothetical parent company have been included in the operating cost estimates.Although the Black Lung Tax is partially determined by the selling price of the coal,there is a cap of $0.50 per ton whenever the selling price is more than $12.50 per ton. Since that is true for all the cases examined,the Black Lung Tax is included in this table'.An allowance of 4.5 percent of the average annual operating expenses plus average depreciation per ton was included to cover parent company overhead to support this operation • 35. - C"" PAUL WEIR COMPANY Capital Costs Representative models of equipment sized to perform the work required were selected for cost estimating_Equipment prices were based on January, 1985 budget level estimates from our files adjusted to include freight and erection costs:a 5 percent contingency allowance was added to the price of each item of equipment. The estimated price of tires on rubber-tired equipment items was subtracted from the unit capital cost to arrive at the depreciable base. No allowance was made for salvage value.An estimate of the service life of each item of major equipment was made based on manufacturers'recomrnenda- tions and the estimated severity of the work load. Summaries of the capital costs and depreciation bases are presented for the major equipment items in Tables No.2 A through No.2 D for the four mi'ne studies. Estimates of the cost of mine infrastructure items,including offi- ces,shops and warehouses and coal handling facilities,as well as site pre- paration and townsite cost allocation were estimated based on the equipment fleet requirements and personnel levels at the mines.Townsite costs were provided by H-E based on manpower levels provided by us.A IS percent contin- gency allowance was included in the infrastructure costs. 36. -i - ..... PA UL WE I R COM:PANY The total annual equipment shifts required to do the work were gener- ated while calculating the operating costs.These shifts were scheduled to determine the number of individual items of equipment required each year. Fleets of equipment were purchased and replaced as the accumulated total of operating shifts equaled the estimated service life of the equipment items. Minor equipment items and auxiliary mine equipment were purchased as required by the buildup in production and manpower.These items were replaced at the end of their estimated lives. The purchase and replacement schedules thereby generated were used to formulate capital expenditure schedules.Infrastructure item costs were also scheduled to correspond with the development of the mine.Tables No. 4 A through No.4 D present the schedule of capital cost expenditures for the four cases. To allocate the cost of capital to the tonnage produced by the capi- tal items,annual depreciation was calculated based on the service life of the equipment. The costs of exploration and lease acquisition,developmental dril- ling and engineering and mine permitting were estimated based on the size of the hypothetical deposit.A contingency allowance of 15 percent was includ- ed in these estimates.These costs were amortized rateably over the tons of coal produced • 37. PAUL WEIR COMPANY Preproduction operating expenses of the mine such as initial strip- ping and haul road construction were also amortized rateably over the tons of coal produced by the mine.

These prices are presented in Tables No.5 A through No.5 D. The total cost of production includes the following: •The direct operating costs calculated in Tables No.3 A through No.3 D. •Royalty at an assumed rate of l2~percent of realization on all coal mined. •Alaska Mining License Tax beginning with the fourth year of produc- tion (except in Case 3 where incremental production is taxed from the start of production).The tax is $4,000 plus 7 percent of gross profit in excess of $100,000 before Federal Income Tax,but after depletion allowance. •Service life depreciation. ir-'--, I I PAUL WEIR COMPANY The total cost of production for calculation of Federal Income Tax includes the following: •The total cost of production described above. •Accelerated depreciation was substituted for service life depre- ciation.It was calculated from the capital cost schedule using the accelerated cost recovery system property classes and reduced by one-half the investment tax credit.The amount of accelerated depreciation is shown in Tables No.5 A through No.5 D. Federal Income Tax paid was calculated from income before tax deduc- tions as follows: •Any tax loss carried forward was taken into account. F'"' I C..... I, (I' •Percentage depletion equal to 8.5 percent of realization minus royal- ty with a maximum of 50 percent of gross profit.(The statutory depletion allowance of 10 percent was reduced by 15 percent because the adjusted basis of the property is relatively insignificant.) •Federal Income Tax liability was calculated at a flat rate of 46 percent. 40. - PAUL WEIR COMPANY •An investment tax credit was taken in the year capital items were purchased.Items with a 3 year life yielded a 6 percent investment tax credit,longer lived items a 10 percent investment tax credit. The amount of investment tax credit is shown in Tables No.5 A through No.5 D. Net cash flow from operation was calculated as follows: .... • • Profit after tax equaled profit before tax minus Federal ln~ome Tax paid. Gross c~sh flow equaled profit after tax plus service life deprecia- tion • •Capital expenditures as shown in Tables No.5 A through No.5 D were deducted. • • Final reclamation and mine closing costs estimated as $10 million were charged in the year following the end of production. An allowance for working capital equal to 3 months operating costs and royalties was maintained throughout the mine life.This working capital was recovered at the end of the mine life. 41 • PAUL WEIR COMPANY The stream of cash flows from the properties was discounted at a real rate of return of 8.2 percent in accordance with instructions from H-E. (This real rate of return reflects an underlying rate of inflation of 5.5 percent in all costs as directed by H-E.Nominal rate of return is 14.2 per- cent.)
