BOWIE RESOURCES LIMITED <br />Bowie No. 2 Mine <br />Coal Mine Waste Bank Inspection - 2nd Quarter 2004 <br />On June 30, 2004, 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 to damp. All organic <br />material and topsoil has been removed ahead of the waste bank founding. <br />The construction of the pile has progressed above the fourth terrace (=6140'). The out <br />slopes of the lower three terraces have been covered. The depth of cover has not been <br />verified. <br />Most of the coal mine waste was generated from the preparation plant. Approximately <br />8,900 tons of gob were hauled to the gob pile with on{y about 500 tons from the mine. <br />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 afront-end loader. Compaction tests were performed <br />on June 29`". All of the tests attained at least 90% of the maximum dry density attained in <br />a laboratory compaction test in accordance with ASTM D698. Relative compaction test <br />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 likely be con~,a~~' bench below <br />the pile and or within the gob pile sediment pond. °°c~ ~°'°•'° S••: F,~•~ <br />O~,e ~` 5 lOG, F~~ <br />~ G a c . • <br />Date <br />P.E.
