2.05.3 <br />The rock entries necessary to cross the fault in the B-Seam will be <br />developed in the same manner as the D-Seam entries. They will be <br />supported as necessary to assure safety of the miners and to assure any <br />debris within the fault plane is supported in place and not allowed to cave or <br />flow into the mine. Roof support may include additional bolting, steel sets, <br />steel sets with lagging and fill above the steel sets to assure fault debris is <br />supported and contained. <br />Mining has advanced through the fault in the D-Seam and developmentwork <br />is ongoing for longwall panels WD1, WD2 and WD3. The longwall mining <br />faces will be developed about 850 feet wide and will vary in length from 2800 <br />to 6200 feet. Gates entries will typically be developed with three entries with <br />pillar spacing and size designed to provide maximum support for ventilation <br />and belt haulage. Bleeder entries will be developed with four or more <br />entries. <br />The new unit train loadout is located south of the UPRR mainline. The <br />Terror Creek Loadout and its associated activities are located north of the <br />• UPRR mainline. Therefore, the Operator and the Terror Creek Loadout will <br />not have overlapping permit areas. <br />~~ <br />PR-OS 2.05 - 5 - 2/03 <br />fiPPRevE9 <br />9~ZS Jo3 <br />
