• <br />C~ <br />undeveloped and is used primarily as wildlife habitat. Recreational <br />activities such as big game hunting, trapping, fishing, and off-road driving <br />also occur in the general area. <br />The portal facilities area near the confluence of Elk Creek and the North Fork <br />is located at the contact of the alluvium of the North Fork and steep upland <br />sedimentary formations. <br />Sanborn Creek Mine portal facilities are just east of Sanborn Creek or <br />approximately one mile east of the town of Somerset. <br />Description of the Operations and Reclamation Plan <br />The Somerset Mine has been in operation since 1902. Operations have evolved <br />from the earlier hand method of mining to the present day operations using <br />continuous mining equipment. <br />The mining system was conventional room and pillar mining using continuous <br />miners, shuttle cars, conveyors and7or rail cars. All coal was moved to the <br />surface using rail cars. Approximately 12 to 14 feet of the B seam were mined <br />in the development and retreat cycle. Annual production in the mine was <br />approximately 900,000 tons per year. <br />Once at the surface, the rail cars dumped the coal at the dump station where <br />it was conveyed to the tipple. The coal was crushed at the tipple then <br />conveyed to the coal storage Silo. The silo, a cylindrical cement structure, <br />straddles the Denver and Rio Grande lJestern Railroad track and loads unit <br />trains. <br />The Sanborn Creek addition to the Somerset Mine is located approximately one <br />mile east of the town of Somerset. This part of the mine is being developed <br />and mined using conventional room and pillar tec'nniques ~.vit'n t'ne same <br />COnV2nt10n31 egUlpmenL a5 previously discussed, e:<cept that conveyors are Used <br />in place of rail cars. Annual. production of this part of the mi^e is <br />projected to be about 70,000 tons per year. Upon opening the portals, coal <br />was first trucked to the tipple at the Elk CreeK yard. A conveyor system was <br />built while developing the first part of the Sanborn Creek mine addition. The <br />conveyor system is used instead of haul trucks to convey coal from the Sanborn <br />Creek portals to the tipple at the Elk Creek yard. <br />The Sanborn Creek East Tract is located adjacent to the original Sanborn Creek <br />Mine on the eastern boundary and is an underground continuation of the Sanborn <br />workings. No additional surface disturbance is required. Method of <br />operations and production rate projections will remain the same as for the <br />original Sanborn Creek 14ine. <br />Development waste (gob> i; disposed of on the surface in the presently <br />approved gob pile on the Elk Creek yard. Non-combustible mine development <br />~.vaste will be disposed of underground in finished C-seam mine .vorkings in a <br />fashion approved by the '4ine Safety and Health AdminisLr3tion, <br />As the mine ha; been in operation since 1902, much of the disturbed area <br />associated wit'n t'ne mine ~,ias affected prier to t'ne effective date of the <br />Surface Mining Control and Reclamatlon Act of 1977 and the Colorado Surface <br />-~- <br />
