West Elk Mine <br />6) The use of persistent pesticides is not anticipated. <br />7) Mountain Coal Company will, to the extent possible, prevent, control, and suppress range, <br />forest, and coal fires which aze not approved by the DOW as part of this or any other <br />management plan. <br />8) Since wildlife habitat is to be the secondary post-timing land use, MCC has selected plant <br />species to be used on reclaimed azeas based on the following criteria: <br />a. Their proven nutritional value for wildlife. <br />b. Their use for cover for wildlife species. <br />c. Their ability to support and enhance wildlife habitat after release of bond. <br />These factors have been discussed in other portions of the permit document. As discussed, the intent <br />of MCC is to distribute the plant species in clusters so as to maximize the benefit to wildlife. This <br />will provide adequate edge effect, cover and forage benefits for the wildlife species occurring on <br />and adjacent to the site. <br />Protection of Public Parks and Historic Places - 2.05.6(4) <br />Operations at the West Elk Mine are not located near public pazks or historic places; therefore, this <br />• section does not apply. <br />Sun`ace Mining Near Underground Mining - 2.05.6 (5) <br />There aze no surface mining operations proposed neaz the West Elk, Mine. <br />Subsidence Survey, Subsidence Monitoring and Subsidence~Control Plan - 2.05.6 (6) (a- <br />f) <br />The extraction of the B-Seam coal, aswell as E-Seam coal in Sections 28, 29, and 30, in the permit <br />azea will be completed using longwall mining methods. The resulting disequilibrium due to <br />longwall mining causes surface subsidence. As stated by Peng in'Surface Subsidence Engineering <br />(1992), "When total extraction is used, it produces a large void in the coal seam and disturbs the <br />equilibrium conditions of the surrounding rock strata. The rock strata bend downwazd while the <br />floor heaves. When the excavated area (gob) expands to a sufficient size, the roof strata will cave. <br />As a result, the overlying strata continue to bend and break un61 the piles of the fallen rock <br />fragments aze sufficiently high to support the overhanging strata. At this time, the overlying strata <br />no longer cave, but bend and rest on the underlying strata. Strata bending in subsidence develop <br />upward until reaching the surface and forming a subsidence basin. The whole overburden strata and <br />the surface subsidence basin will further go through a period of compaction and gradually become <br />stabilized." <br />C~ <br />2.05-97 RevisedJwx 1995 PR06; Revised Jan. 1996 RN03; RevrsedJan. /998 PR08 p ,u~ ,( <br />~~-t) <br />
