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 a seven-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 a five-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-13-3 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 />
