BOWIE RESOURCES LIMITED <br />Bowie No. 2 Mine <br />Coal Mine Waste Bank Inspection - 2nd Quarter 2002 <br />On June 19, 2002, 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 />I, J. E. Stover, P.E., have a wide variety of experience in the design and construction of <br />earth fill embankments. Nothing was observed during the inspection that would indicate <br />the pile has a potential for failure. The gob disposal area was dry. All organic material <br />and topsoil has been removed ahead of.the waste bank founding. <br />The construction of the pile has progressed to nearly the level of the third terrace (6110'). <br />The out slopes of the terraces have been covered. The depth of cover has not been <br />verified. <br />The coal mine waste generated during the quarter all came from the mine. Approximately <br />14,180 tons of gob were hauled to the gob pile. Coal mine waste is to be placed in the <br />pile in approximately horizontal lifts no more than 24-inches thick. The coal mine waste is <br />spread and compactive effort is provided by a self propelled sheepsfoot compactor or a <br />front-end loader. Compaction tests were performed on May 29`h and June 25`h on the lifts <br />compacted during the quarter. Relative compaction test results are enclosed. <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 below <br />the pile. Additionally, the gob pile sediment pond is located below the pile. If the coal <br />mine waste bank failed, the material would very like be contained on the bench below <br />•y ~r <br />the pile and or within the gob pile sediment pq~~D REG/sl <br />o`~ • S E.
