:J <br />0 <br />2.05.3 <br />2.05.3 Operation Plan - Permit Area <br />(1) Production Methods and Equipment <br />Underground mining will be conducted at the mine in the B -Seam and D <br />Seam by both room and pillar and longwall mining techniques. Conventional <br />room and pillar mining will utilize continuous miners and shuttle cars with belt <br />haulage. Longwall gate entries and bleeders will be developed with <br />continuous miners and shuttle cars. Newly exposed roof will be supported <br />according to an approved roof support plan that recognizes full roof bolting <br />and additional support materials as required due to local conditions. <br />Development mining will generally be in the upper 8 to 10 feet of the seam. <br />Rooms will be driven on retreat with extraction of room and entry pillars. Up <br />to 3 -feet of top coal may be left as a beam to support the mudstones that <br />may be located immediately above the coal roof. Where the seam is thick <br />enough, an additional two to four feet of bottom coal will be mined during the <br />retreat cycle of mining with the objective of extracting 10 feet of the seam. <br />Retreat mining is conducted to attain the maximum recovery consistent with <br />the safety and protection of mine personnel and surface protection. <br />Coal will be loaded from the working face by the continuous miners utilizing <br />shuttle cars that transport the coal to the conveyor belt loading point. <br />Conveyor belts transport the coal to the surface. <br />The production rate at the mine will be controlled by market conditions. The <br />minimum production rate will be about 2.0 million tons per year with an <br />expected maximum production of 6.0 million tons per year. However, mine <br />plan projections will continue to be based on 5.0 million tons per year <br />production level. <br />Other than safety of the miners and protecting the environmental resources, <br />maximum recovery of the coal reserve is the objective of the Operator. This <br />is accomplished by sound engineering plans based on prudent mining <br />practices. <br />Three entries were used to access the D -Seam reserve. The B -Seam was <br />also accessed with three entries. The D -Seam was expanded to five or <br />more entries when mining and physical conditions allowed. Likewise ttie B= <br />Seam was expanded to five or more entries when mining and physical <br />PR -12 2.05-5- 02/10 <br />11/1--f/6 <br />
