West Elk Mine <br />Mine's main portals are in the F Seam at an elevation of approximately 6,450 feet AMSL in an area <br />of covered slope and semi - consolidated slump debris. Additionally, access into the mine is <br />provided through the intake air shaft in Sylvester Gulch. Map 33 is a location snap of the portal <br />entries. Map 53 also shows the location of the portals. Sloped entries within the mine provide <br />access from the F Seam down to the E and B Seams. <br />Table 32 <br />Projected Employment Needs at West Elk Mine for the Life of Mine <br />Coal Production <br />Total Employment <br />millions of tons er year rounded <br />number of pers ons at ear -end <br />Year <br />Actual <br />Projected <br />Actual <br />Projected <br />1997 <br />5.5 <br />- -- <br />292 <br />- -- <br />1998 <br />5.9 <br />- -- <br />275 <br />- -- <br />1999 <br />7.0 <br />- -- <br />324 <br />- -- <br />2000 <br />3.4 <br />- -- <br />398 <br />--- <br />2001 <br />5.0 <br />- -- <br />359 <br />- -- <br />2002 <br />6.6 <br />- -- <br />363 <br />- -- <br />2003 <br />6.5 <br />- -- <br />375 <br />- -- <br />2004 <br />6.6 <br />- -- <br />380 <br />- -- <br />2005 <br />5.6 <br />- -- <br />425 <br />- -- <br />2006 <br />6.0 <br />- -- <br />430 <br />- -- <br />2007 <br />6.9 <br />- -- <br />433 <br />- -- <br />2008 <br />5.9 <br />- -- <br />433 <br />- -- <br />2009 - 2010 <br />- -- <br />6.0-6.5 <br />- -- <br />430 <br />2011 -2018 <br />- -- <br />7.0 <br />- -- <br />430 <br />In all portal excavations, the material removed before reaching the F Seam is colluvium consisting <br />of weathered debris, mainly sandstone blocks and clay. To assure stability in the main portal area, <br />these colluvial materials were excavated and a concrete retaining wall was installed (Map 33). Logs <br />of drill holes in the portal area are shown on the cross - sections shown in Exhibit 15. <br />The main surface facilities consist of sediment control structures, coal handling facilities, support <br />facilities for mine operations, and other related facilities. Support facilities for mine operations <br />include the offices, maintenance shops, warehouses, and bathhouse. Other related facilities include <br />coal refuse disposal sites, equipment and material storage areas, and the mine ventilation fans. The <br />surface facilities in Sylvester Gulch include but are not limited to mine ventilation shafts and fans, a <br />substation, powerlines, electric mine borehole, nitrogen supply and methane drainage facilities, rock <br />dust storage, mine water and sediment ponds and control structures, compressed air and other <br />support facilities. Sediment control structures and coal handling facilities are described below in <br />Sections 2.05.3(4) and 2.05.3(7), respectively. Waste handling facilities are discussed in Sections <br />2.05.3(6), 2.05.3(8), and 2.05.3(9). The main support facilities for mine operation are described in <br />this section. <br />General Construction Procedures <br />All work at West Elk Mine is conducted according to Federal and State water pollution laws, land <br />reclamation statutes and regulations, and construction safety standards. Construction activities are <br />planned and executed in a manner to protect the environment and minimize pollution and erosion. <br />Three areas of primary concern during construction projects are safety, vegetation, and fires. <br />1.05 -16 Rev. 06105- PRIG; 01106- PRIG; 03106- PRIG; 04106- PRIO, 05106- PRIO; 01109 - MR- 350; 0=1109- TR 116; 04109- MR353 <br />
