• <br />Backfillinq and Soil Stabilization <br />All areas affected by the surface facilities within the permit area will <br />be returned to a final surface configuration that closely resembles the <br />land surface prior to mining. This configuration will conform to the <br />drainage pattern of the surrounding terrain. The existing topography is <br />shown on the Vegetation Map (Flap )~3). The anticipated post-mining <br />topography is shown on the Post-Mining Topography Map (Map 14). <br />The final grading in all areas will be done along the contour, unless <br />site specific slope conditions would cause a safety hazard to the <br />operator. The final surface configuration will approximate the overall <br />pre-mining topography. Following grading, all disturbed areas will blend <br />in with the undisturbed areas outside the limit of the affected area. <br />Portal Areas. Because the location for the Coal Gulch Mine portals has <br />been previously affected by past mining, no major changes will be <br />• necessary by Peerless Resources, Inc, in order to prepare the site for <br />resumed mining. In the canyon areas of Coal Gulch, the steep topography <br />resembles in many places what could be called a "natural highwall". The <br />planned post-mining surface landscape of the portal face-up for the Coal <br />Gulch Mine will blend into and complement that existing topography. <br />The coal deposits along Coal Gulch lie in Cretaceous rocks. As a result <br />of regional uplift and constant erosional processes, the formations with <br />Cretaceous rocks are characterized by somewhat steep topography along <br />Coal Gulch. Hence, the coal is exposed in an essentially narrow canyon <br />on the faces of what Colorado characterizes as naturally occurring <br />highwalls, formed over centuries. Due to the increasing overburden <br />thicknesses in this area with these outcrops, most of the portal areas <br />of past underground mines along Coal Gulch lie along the steep outcrop <br />of the coal, with the development of portals into the coal seam. <br />The result of this method of extracting coal is the development of <br />• benches, roads and other surface operation facilities in the somewhat <br />steep topography.
