Chapter II <br />Development of the underground workings for each entry occurred as follows: <br />• No. 1: The main entry was driven down the 11 to 13 degree dip of the coal seam. <br />The mine was developed with aseven-heading set of entries, driven westerly from <br />the outcrop a distance of 7,000 ft. Coal producing sections have been driven both <br />to the north and to the south of the main slopes. <br />No. 2: The main slopes of No. 2 are more or less directly above the main slopes of <br />No. 1. The mine was developed to the north and to the south of a six heading main <br />slope entry driven westerly from the coal outcrop. Development and production <br />sections have been driven northerly and southerly from the main drifts. <br />No. 3. The mine was developed with a six heading main entry driven westerly <br />downdip (12 degrees) from the outcrop. Production entries are driven northerly and <br />southerly from the main slopes. <br />No. 4: The mine was developed by a six heading main drift driven downdip (12 <br />degrees) southwesterly from the outcrop. <br />No. 5. The mine was developed with afive-heading main entry driven westerly along <br />the southern mine boundary. Production entries were driven to the northwest, <br />approximately 4,000 ft. The present southern boundary of the mine is determined <br />by the location of a large igneous dike and a parallel and probably associated fault, <br />both of which run essentially east/west. The northern boundary of the mine is <br />determined by another major east/west trending fault. <br />Adit/Rock Tunnel: The Adit/Rock Tunnel extends westerly, to intersect both the <br />B-bed and M-bed seams at the workings of No. 1 and No. 2. The Adit/Rock Tunnel <br />has been driven from an area at approximately 8,600 elevation, at a relatively flat <br />grade of 1 to 4 degrees, and consists of two parallel entries. The Adit/Rock Tunnel <br />intersects the B-bed approximately 13,000 feet west of the portal, and intersects the <br />M-bed approximately 14,665 feet west of the portal. Exhibit II-B-3 profiles the <br />Adit/Rock Tunnel. <br />c. Anticipated Mining Sequence - <br />Permit Term (1988-1993) <br />Exhibits II-B-2 and II-B-3 show the anticipated mining during the permit term. It is <br />anticipated that coal will be mined from both seams, extending west and south of <br />the current workings. <br />Coal will be transported from the working faces to the surface through the Adit/Rock <br />Tunnel <br />Future plans are to extend the Adit/Rock Tunnel laterally to insersect with the <br />. workings of Nos. 3, 4 and 5; however, at the time of this permit application submittal <br />14 <br />
