• Because the mining system will be a continuous room and pillar plan, <br />sets of rooms will be driven at approximately 9C° from the main entries. <br />Each set of room entries or panels will be separated from the adjacent <br />panels and the main entries by a barrier of coal as shown on the Mine <br />Plan Map (Map 111. These pillars will be left between each panel and <br />the main entries <br />In order to visualize the overall room and pillar method of mining, a <br />diagram showing the room dimensions is found on the Mine Plan Map (Map <br />11). <br />The anticipated annual and total production of coal from the A Coal Seam <br />is shown in Table 5, Projected Coal Production. <br />By utilization of the surface area disturbed by previous mining <br />activities of the Arness-McGriffin Coal Company, Peerless Resources, <br />• Inc. proposes increased recovery of reserves and no additional surface <br />disturbance. The main entries will be oriented as shown on the Mine <br />Plan Map (Map 11), which will result in a greater recovery of reserves <br />of the "A" Coal Seam during the coal extraction process. <br />The main entries will run parallel to one another and will be separated <br />by blocks of coal called pillars. The drift entries will begin with a <br />minimum number of portal entries then expand to a five (5) main entry <br />system, in order to improve mining and ventilation. The main pillars <br />which separate these entries will be designed to provide support over <br />the life of the mining of the "A" Coal Seam; they are projected at <br />60-foot centers. The width of the mine openings will be kept at, <br />approximately 18 to 20 feet throughout mining operations. The main <br />entries will serve as the lifeline of the mining operation, providing <br />access for the supplies, water piping, haulage, power, ventilation and <br />support services. <br />• <br />~ `,:~~ <br />2.05-3 <br />
