~. <br />BOWiE RESOURCES LIMITED <br />Bowie No. 1 Mine <br />Coal Mine Waste Bank Inspection - 1s` Quarter 2002 <br />On March 29, 2002, I performed a quarterly visual inspection of the Bowie No. 1 Mine <br />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. All organic material and topsoil has been removed <br />ahead of the waste bank founding. The pile and surrounding area were dry. No <br />seepage was noted around the pile. <br />Approximately 7,000 cubic yards of coal mine waste were deposited in the pile during <br />the quarter. The pile was basically filled to capacity during the quarter. There were no <br />drainage alterations and no new bench construction. Material including some topsoil <br />was removed from the north founding and placed on completed portions of the pile. <br />Compaction tests were performed on January 7"'and 8`h and January 16"' and 17`h <br />The relative compaction test results are enclosed. <br />The design of the waste disposal area is presented in Volume 6A. To the best of my <br />knowledge and belief, based on my inspection of the pile and previous inspections by <br />professional engineers, the coal mine waste bank has been constructed in accordance <br />with the approved plan. <br />The pile is located in a remote area welt away from human habitation. A failure of the <br />pile might damage the mine haul road located below the pile. However, a failure of the <br />pile would probably not be a hazard to human life <br />. <br />e <br />4H <br />e P < <br />4 ~0 Oesa® <br />R=,~S°s <br />a~» <br />l <br />e <br />Recommend maintenance: None _ o~o.~~S , <br />E s~~ <br />f~~ <br /> <br />~~iP + <br />Te~4 <br />~ ~1 ..~ ,. ~,. ~~ f <br />O Z <br />
