IV.B.2 Mine Service Buildings <br />Two mine service buildings are located at "D" Portal Area, a Change House and aShop-Warehouse. <br />The change building contains showers, dressing rooms and associated facilities for the employees. The <br />shop•warehouse building contains a maintenance shop and storage facilities. The warehouse stores <br />replacement parts and consumables required for mine operation. A loading dock receives material <br />where it is transferced to mine vehicles for distribution inside the mine. <br />The plan area of each building is approximately as follows: change building - 8,000 square feet, and <br />shop-warehouse - 20,000 square feet. The service buildings were constructed on concrete footings with <br />floating concrete slabs. The sides and roofs are covered with metal sheathing. <br />A moveable storage shed is currently (1999) located at the Refuse Disposal Area adjacent to the haul <br />road in Sub-Area 5-a. It is an all steel building with steel railroad tie floor. Its main function will be the <br />storage of reclamation equipment and supplies. It also contains a break room for personnel assigned to <br />the Refuse Area. <br />When a mine service building is no longer required, the structure will be disassembled and removed. <br />The concrete foundations will be buried or demolished during the regrading portion of the reclamation <br />effort. <br />• IV.B.3 Rock Dust Bin Rock dust bins are located in the "D" Portal Area and at a rock dust dispensing <br />hole (RDH-1) drilled from the surface to the East Mains (see Map ij. A second rock dust bin facility for <br />B-Seam workings will be built near a proposed rock dust dispencing hole (RDH-2). See Mpas 138 and <br />154. The rock dust bins store approximately 150 tons of material. The bins consist of round steel tanks <br />approximately 30 feet high sealed on the ends to prevent moisture from entering. The legs are bolted to <br />concrete foundation pedestals. At the end of mine operations, the bins will be disassembled and <br />removed. The concrete foundations will be covered during reclamation. <br />IV.8.4 Explosive Storage Explosive storage facilities are located at the "D" Portal area as shown on <br />Maps 15 and 25. Outside distributors will supply explosives and magazines when needed. The <br />magazine will be left on site in the explosive storage area during the blasting operation. No explosive <br />will be stored for an extended amount of time beyond blasting needs. Explosives storage and use is <br />regulated by the Colorado Division of Mines and the U.S. Department of Treasury. <br />IV.6.5 Surface Blasting Plan BME complied with all applicable state and federal regulations while <br />conducting surface blasting activities. Each person who conducts surface blasting will comply with all <br />state and federal laws in the use of explosives. Blasting operations will be conducted by experienced, <br />• Mine Permit Renewal #3 (Rev. 8/99) IV-4 <br /> <br />
