Chapter II <br />d. Light Use Roads. <br />• The roads leading to Mine Portals #3, 4 and 5 have been designated, and are being <br />maintained, as light use roads until resumption of mining from portals #3, 4 and 5. At <br />that time these roads will be used for coal haulage, as they were previously. The <br />drainage system designed for the haul road usage has been maintained, as indicated in <br />App. II-B-7 Att. 2. The applicable road segments are indicated at II-B-App.7-Att.2 as <br />Roads C, F, E and G. <br />During the preceding permit term, Mid-Continent received permission to upgrade and <br />extend alight-use road segment which reaches from Coal Basin over Huntsman Ridge, <br />to the west side, above the underground workings. Technical and minor revisions were <br />approved by MLRD. The uses of the road include subsidence monitoring, exploration <br />activity, and access to drill sites for a planned coal degassification program. <br />The segment extending from No. 4 portal to the top of Huntsman Ridge has been <br />constructed. Some work will be done on sections of an existing drill road on the west <br />side of Huntsman Ridge. An additional two miles of new road will be constructed, <br />extending to the north over Gunnison National Forest and Mid-Continent fee land. <br />Exhibit II-B-6 indicates light-use roads as they occur within the permit area. <br />e. Public Road - Highway to Mine Facility <br />• The central complex area is accessed by a four-mile road which leads to/from Colorado <br />State Highway 133. The road follows most of the way along the rail line laid at the turn <br />of the century, and has been in use as a road since approximately 1953. <br />f. Conveyor System <br />Conveyor belts are used exf~nsively in the Mid-Continent operations. Exhibit II-B-7 <br />shows the system. <br />The uses are as follows: <br />Mine face to surface storage. Coal is transported from the working face through one <br />entry of the Adit/Rock Tunnel and overland to the raw coal stockpile(s), where it is <br />deposited. <br />The coal is then conveyed by belt from raw coal storage to the preparation plant, <br />separated from rock, and conveyed by belt to clean coal storage; meanwhile, the <br />refuse is conveyed fromt he wash plant to the Sutey Refuse pile for disposal. <br />• <br />21 <br />~, ,. <br />
