• <br />2.05.3 <br />conditions allow. Mining conditions will dictate entry and cross -cut spacing. <br />Cross -cut spacing will range from a minimum of 50 -feet to a maximum of <br />150 -feet. Entry spacing will range from a minimum of 50 -feet to a maximum <br />of 120 -feet. Room and pillar panels will be developed off main and submain <br />entries with barrier pillars left for protection. Partial pillar recovery of all <br />workings and barrier pillars will go on to the extent allowed by safe mining <br />and surface protection concerns. <br />Main entries in both the D and B -Seams will be developed down dip in a <br />northerly direction. Submains will be extended both westerly and easterly <br />from the mains. Panels will be driven at .90 degrees from the submain <br />entries. Each set of panels will be separated from the adjacent panels and <br />submains by barrier pillars. <br />Longwall mining faces will be developed as long as possible and 800 to <br />1,000 feet wide. Gates entries will typically be developed with three entries <br />with pillar spacing and size designed to provide maximum support for <br />ventilation and belt haulage. Bleeder entries will be developed with four or <br />more entries. <br />A fault bisects the private reserve in a northwest southeast direction. The <br />reserves on each side of the fault will be referred to as the east and west <br />pods. The D -Seam was initially developed in the east pod. The B -Seam was <br />initially be developed in the west pod. <br />The D -Seam west mains were advanced towards the fault. The operator <br />drilled three holes into the fault from the west mains. No significant water <br />was encountered in the fault. The fault was damp to dry. The west pod is <br />about 28 -feet below the east pod. Three rock slopes were excavated at a <br />12% grade which resulted in the slopes being approximately 230 feet long. <br />Two 16 -foot diameter shafts were excavated adjacent to the rock slopes to <br />improve ventilation. The rock excavated from this development was <br />permanently stored in rooms excavated specifically for that purpose. <br />Appropriate approvals were obtained from MSHA for both driving the slopes <br />and storing waste rock underground. <br />The D -Seam slopes were supported with roof bolts. No supplemental <br />support -was necessary and no debris within the fault plane was encountered. <br />PR -12 2.05-6- 02/10 <br />APPRavSL) <br />11/16 ()a <br />
