<br />BOWIE RESOURCES LIMITED <br />Bowie No. 2 Mine <br />Coal Mine Waste Bank Inspection - 2nd Quarter 1998 <br />On June 25, 1998, I performed the required quarterly visual inspection of the Bowie No. <br />2 Mine coal mine waste bank in accordance with Rule 4.10.2. <br />The gob disposal area was dry, and the gob being placed in the pile was dry. I, J. E. <br />Stover, P.E., have a wide variety of experience in the design and construction of earth <br />fill embankments. Nothing was observed during the inspection that would indicate the <br />pile has a potential for failure. All organic material and topsoil has been removed <br />ahead of the waste bank founding. <br />Coal mine waste is placed in the pile in approximately horizontal lifts no more than 24- <br />inches thick. At the time of the inspection, a substantial amount of material had been <br />placed in the pile but not yet compacted. This material was spread and compacted by <br />the end the quarter. The coal mine waste is spread with a D-9 Caterpillar Track Dozer <br />and compactive effort is provided by a self propelled sheepsfoot compactor. <br />Compaction tests were performed on April 22"d and June 30d' for the second quarter of <br />1998. All of the compaction tests attained at least 90 percent of the maximum dry <br />density attained in a laboratory compaction test in accordance with ASTM D698. <br />The coal mine waste generated during the quarter was from routine operations in the <br />mine. According to the contractor which hauled the coal mine waste to the pile, a total <br />of 851 loads were hauled during the quarter (7,148 in place cubic yards @ 8.4 cy/load <br />@ 12 tons per load). <br />A failure of the pile would probably not be a hazard to human life. The pile is located <br />above a large flat bench. The bench is approximately 80 to 150-feet wide directly <br />below the pile. Additionally, the gob pile sediment pond is located below the pile. If the <br />coal mine waste bank failed, the material would very likely be contained on the bench <br />below the pile and or within the gob pile sediment pond. <br />~~p~REG!'• <br />•~p~,,.E....sl•~ <br />~ Off`.
