<br />3. Operation Plan - Permit Area <br />The location of the mining activity is in the SE NE ;, Section 24, T5S, <br />R92W, 6th Prime Meridan. The Eastside Mine is in the outcrop of the "E" <br />coal seam, in the east side of Harvey Gap. The coal seam at the Harvey Gap <br />Project mining site is approximately twenty (20) feet thick. The seam dips <br />at fifty-nine (59) degrees to the south. The entries will be driven into <br />the coal in an easterly direction on an upward slope of 1-2%. This will <br />allow water to drain from the face to a central pumping station. <br />Once the boundary of coal burn is determined by underground drilling and an <br />adequate coal safety zone is established, then entries will be driven up at <br />twenty percent (20%) grade (see Map HGP-4: Mine Plan). Based on currently <br />known geologic conditions and presumptions of mining methodologies to be <br />tested in this mining activity, Eastside anticipates a two entry system will <br />be initially developed into the coal seam for an approximate distance of 3,500 <br />feet to the lease boundary. <br />Coal will be mined across the pitch (59 degrees) by using continuous miners. <br />The coal will then be hauled outside the mine with diesel haulage equipment. <br />Upon completion of the initial two entry system the coal down dip will be <br />developed by driving one entry to the east boundary. Pillar recovery will <br />commence as soon as a minimum of four levels are completed. The upper pillars <br />will be recovered first working from the property boundary back to the <br />portal area. <br />Future ming will proceed downdip in the coal seam until a depth is reached <br />which precludes further mining. The present depth being considered as a <br />cutoff point is 2500 feet of overburden. As the mine is advanced downdip <br />development of the area to the west of the portal area will be started. <br />The area to the west will be developed and mined in the same manner as the <br />eastern part of the mine. <br />90 <br />Revised 2/91 <br />
