• Equipment. The proposed machinery for the <br />equipped, maintained, and operated to <br />productivity, and quality of coal production. <br />Sunbelt operations will be <br />insure maximum safety, <br />All underground equipment will be approved by the Mine Safety and Health <br />Administration. The major underground and surface equipment to be <br />utilized is set forth in Table 6, Equipment List. <br />Room and Pillar Mining. Room and pillar mining will account for all the <br />total projected tonnage. This mining will be accomplished utilizing <br />a conventional mining system. The room and pillar mining cycle will <br />consist of coal removal from each entry and panel in a sequence <br />indicated on the Mine Plan Map (Map 8). <br />The mining cycle during development will consist of the following steps: <br />1. Extraction. In a conventional mining system, the coal is <br />• extracted in a sequence of operations, with special equipment <br />to execute each step. The coal face is undercut with a cutting <br />machine (which most nearly resembles a large chain saw on <br />wheels). The block of coal remaining is then drilled using a <br />mobile powered drill. The holes are loaded with explosives, <br />and the coal is dislodged. <br />2. Loading. The broken coal will be collected by gathering arms <br />at the base of the loading machine. These arms will then <br />direct the coal onto a conveyor which will discharge it into a <br />shuttle car. <br />3. Hauling and Dumping. The mined coal will be transported to a <br />load-out point and dumped into a feeder breaker. The feeder <br />breaker will even up the flow of coal, break any lumps larger <br />than 8 inches in diameter, and direct the stream of coal onto a <br />conveyor belt for transport out of the mine. <br /> <br />2.05-11 <br />
