3 .2 Coal Basin Seam or L-Saari (formmer 1-:4ine) <br /> The former 1-Mine is operated by Mid-Continent in the <br /> Coal Basin seam or the B-seam, the lower of the two principal coal <br /> seams mined by Mid-Continent, in Coal Basin, near the village of <br /> Redstone, Pitkin County, State of Colorado; at the west end of the <br /> Elk Mountain Range. <br /> The former 1-Mine is a slopes-type mine which enters the <br /> coal seam at the outcrop at an elevation of approximately 10, 000 <br /> msl. Multiple entries constitutes the slopes section of 1-Mine. <br /> The slopes entries were progressively developed down-dip as the <br /> mining sections to the right and left (north and south, generally <br /> along the strike of the coal seam) of the slope entries were <br /> developed and mined out. Presently the slope entries extend <br /> approximately 7, 000 feet down-dip, and there are approximately six <br /> old, mined out sections bordering each side of the slope entries. <br /> The last mining activity in the former 1-Mine mining <br /> section was the 103 advancing longwall panel mined off of and to <br /> the north of the slope entries. Following the first (the 101) <br /> advancing longwall panel development and mining, subsequent layout <br /> and development of mining activities in this coal seam were <br /> changed. <br /> 3 .3 Dutch Creek Seam or M-Seam (2-Mine) <br /> The former 2-Mine is operated by Mid-Continent in the <br /> Dutch Creek seam or the M-seam. This is the upper of the two coal <br /> seams presently being mined by Mid-Continent in Coal Basin. <br /> The former 2-Mine is a slopes-type mine which enters at <br /> the outcrop of the coal seam at an elevation of approximately <br /> 10, 437 feet msl. Multiple entries constitute the slopes section of <br /> 2-Mine. The slope entries were progressively developed down-dip as <br /> the mining sections to the right and left (North and South, <br /> generally, along the strike of the coal seam) of the slope entries <br /> were developed and mined out. Presently, the slope entries extend <br /> approximately 7, 400 feet down-dip, and there are approximately six, <br /> old, mined out sections bordering the north side and three, old, <br /> mined out sections, bordering the south side of the slope entries. <br /> Presently, the last mining activity in the former 2-Mine <br /> mining sections are the 211 and 212 advancing longwall panels mined <br /> off of and to the right of the slope entries. <br /> All of the foregoing active workings are accessed via <br /> the RTP. The RTP provides personnel ingress and egress, the <br /> conduit for power and other mechanical systems, ventilation, and an <br /> entry for conveyering cut coal from the mine. <br /> Mines Sealing $ 75.1711 D R A F T <br /> MSHA Modification - 3 - 13-Nov-92 <br />
