<br /> <br />BOWIE RESOURCES LIMITED <br />Bowie No. 2 Mine <br />Coal Mine Waste Bank Inspection - 4'" Quarter 2000 <br />On December 1, 2000, I performed the required quarterly visual inspection of the Bowie No. 2 <br />Mine coal mine waste bank in accordance with Rule 4.10.2. <br />The gob disposal area was dry. I, J. E. Stover, P.E., have a wide variety of experience in the <br />design and construction of earth fill embankments. Nothing was observed during the inspection <br />that would indicate the pile has a potential for failure. All organic material and topsoil has been <br />removed ahead of the waste bank founding. <br />The construction of the pile has progressed beyond the first terrace (=6050'). The operator began <br />excavating cover material from the gob pile founding and placing the material on the outslope of the <br />pile during the third quarter 1998. During the 2nd quarter 1999 additional cover material was <br />excavated and placed on the outslope of the pile. The entire outslope of the pile, up to the first <br />bench, is covered with subsoil. The depth of cover material placed has not been verified. <br />The coal mine waste generated during the quarter was from the mine. Approximately 560 loads <br />were hauled to the gob pile during the quarter (4,700 in place cubic yards @ 8.4 cy/load @ 12 tons <br />per load). Coal mine waste is to be placed in the pile in approximately horizontal lifts no more than <br />24-inches thick. The coal mine waste is spread and compactive effort is provided by a self <br />propelled sheepsfoot compactor or a front-end loader. Coal mine waste hauled to the pile during <br />the quarter was spread and compacted. Compaction tests were performed on December 18'h on <br />the lift compacted during the quarter. Relative compaction test results, which all passed, are <br />enclosed. <br />A failure of the pile would probably not be a hazard to human life. The pile is located above a large <br />flat bench. The bench is approximately 80 to 150-feet wide directly below the pile. Additionally, the <br />gob pile sediment pond is located below the pile. If the coal mine waste bank failed, the material <br />would very likely be contained on the bench below the pile and or within the gob pile sediment <br />pond. <br />~f~~ <br />James E. Stover Date <br />P.E. No. 19230 <br />
