Chapter II <br /> response to the concerns of MLRD and the OSM, have been included in this permit for <br /> reference purposes. Adit/Rock Tunnel materials are in App. II-B-3, and cover the <br /> period from 1979-1987. Materials relevant to the Sutey Pile (New Refuse Facility) are in <br /> App. II-B-5, and cover the period from 1984-1987. <br /> In addition, because operations have been changed in recent times, a brief description <br /> of recent operations history has been included as Appendix II-B-2, for easy reference <br /> and to clear up any confusion as to changes in operations since the last permit <br /> application for Mid-Continent's Coal Basin operation. <br /> Please note that use of these terms in the CURRENT operations description (Chapter <br /> II) denote the following: <br /> a. Adit/Rock Tunnel. <br /> Describes the twin-bore rock tunnel which provides transportation to and from the two <br /> seams being mined. <br /> Men, equipment and materials are transported through one bore, and coal is <br /> transported from the face through the other. Although this facility has been referred to <br /> previously as "the tunnel" and the "rock tunnel" it will be described as the Adit/Rock <br /> Tunnel to avoid confusion with the rock tunnels at the No. 5 and No. 2 Main Entries. <br /> b. Main Entry or Entry. <br /> The Adit/Rock Tunnel has been operational since the fall of 1987. Before that time, <br /> coal was mined from the two seams through five entries, which followed the coal from <br /> outcrop, at various points around the Coal Basin, downdrift. These were previously <br /> known as Mines No. 1, 2, 3, 4 and 5. The objective of the modernization program has <br /> been to consolidate operations underground into a single operating unit, rather than <br /> five separate units of production. <br /> To be more properly descriptive, the operator will refer to what was Mine No. 1 as Entry <br /> #1, Mine No. 2 as Entry # 2, Mine No. 3 as Entry #3, etc., although some baseline <br /> information and maps which date from an earlier period, may not reflect the changed <br /> terminology. <br /> Entry #1 is the main entry to the B-bed, and Entry #2 is the main entry to M-bed as of <br /> the time of permit submittal. This is indicated on the maps which show current mine <br /> plans by reference to the B-bed Entry and the M-bed Entry. <br /> c. Sutey Pile or Coal Refuse Disposal Area. <br /> 2 <br />
