Chapter II <br />Rock and refuse materials removed from the coal at the preparation plant are <br />conveyed to the coal refuse disposal area, known as the Sutey Pile, by covered <br />conveyor belt. <br />The Adit/Rock Tunnel will, on completion, extend laterally to access the workings of <br />Entries #3, #4 and #5. These are on stand-by status, awaiting an improvement in <br />market conditions for coal. If production resumes through these entries prior to <br />completion of the Adit/Rock Tunnel, mine operations are as follows: <br />Coal is transported from the working section by conveyor belt, up to the portal, then <br />discharged in the portal area. From the portal area, the coal will then be hauled by <br />truck down the haul roads to raw coal storage. <br />Men/materiel will be transported to/from the portals over the haul roads. Between <br />the portal to working sections of the mine, men/materiel will be transported by <br />mantrip. . <br />b. Major Equipment. <br />The major equipment and its use in underground coal production is as follows: <br />(1) Mining. <br />Longwall shearer. <br />• Function: cuts the coal in a longwall system. <br />Continuous miner. <br />Function: cuts coal, conveys it from the face. They're used to advance headings in <br />solid coal, including entries for main slope development, exploration, ventilation, and <br />in preparation for retreating and advancing longwalls. They're also used to "pull <br />pillars" in room-and-pillar operations. <br />(2) Coal Loading and Transportation. <br />Longwall face conveyor. <br />Function: Transports coal from the longwall face to the stage loader. It runs parallel <br />and adjacent to the face and is located between the face and the shields. <br />Longwall stage loader. <br />Function: Receives coal from the face conveyor, loads it onto the entry belt <br />conveyor. <br />Underground conveyor system. <br />Function: Tranports coal from the working face to the surface, and raw coal storage. <br />Overland conveyor system. <br />Transports coal from portal to storage. <br />4 <br />
