• 2.05.3(2) <br />Equipment. The proposed machinery for the Bear operations will be <br />equipped, maintained, and operated to insure maximum safety, <br />productivity, and quality of coal production. <br />All underground equipment will be approved by the Mine Safety and <br />Health Administration. The major underground and surface equipment <br />to be utilized is set forth in Table 9, Equipment List. <br />Room and Pillar Mining. Room and pillai mining will account for <br />all the total projected tonnage. This mining will be accomplished <br />utilizing continuous miners. Continuous miners will perform two <br />vital functions in the development of mining of the reserves. They <br />will be used in the development of the mains and panel entries, and <br />then in the extraction of coal pillars. <br />The room and pillar mining cycle will consist of coal removal from <br />each entry and panel in a sequence indicated on the B-Seam Mine <br />Plan Map (Map 9A). <br />The mining cycle during development will consist of the following <br />steps: <br />1. Extraction. The continuous miner will make two <br />consecutive cuts side by side, resulting in an entry <br />width of approximately 18 feet. The depth may be up to <br />forty feet with a remote controlled continuous miner. <br />2. Loading. As the continuous miner cuts into the face, the <br />ripped coal will be collected by gathering arms at the <br />base of the continuous miner. These arms will then <br />direct the coal onto a conveyor which will discharge it <br />into an electric shuttle car. <br />3. Hauling and Dumping. The mined coal will be transported <br />to a load-out point and dumped into a feeder breaker. <br />The feeder breaker will even up the flow of coal, break <br />any lumps larger than 8-inches in diameter, and direct <br />the stream of coal onto a conveyor belt for transport out <br />of the mine. <br /> <br />2.05-13 Rev. 11-30-93 <br />
