There was no coal mine waste was generated from the preparation plant during the quarter. <br /> Coal mine waste is to be placed in the piles in approximately horizontal lifts no more than 24- <br /> inches thick. The coal mine waste is dried and then spread and compacted by self propelled <br /> heepfoot compactors. There were sixteen compaction tests were taken at gob pile#3 <br /> during the quarter. There were no compaction tests taken at gob pile#2 during the quarter. <br /> The westernmost and easternmost sections of gob pile #3 serve as drying areas for end <br /> dumped material. The purpose of the gob drying area is to provide an area for temporary <br /> storage of gob for drying purposes. End-dumped gob in the gob drying areas is worked with <br /> dozers and track hoes to assist in the drying process. There was no work at gob pile #3 <br /> during the inspection although placement and compaction efforts have occurred during the <br /> second quarter. <br /> During active mining conditions, it is necessary to stockpile gob material at gob pile <br /> during the winter months, then place and compact the stockpiled gob when weather allows. <br /> Stockpiling of gob can commence November 5 and end April 15. Winter stockpiled <br /> material will be re-handled and compacted by September 30. Beginning on October 1, the <br /> Operator should be compacting all material concurrently, until conditions again require <br /> stockpiling. The stockpiling piling dates listed above should be considered flexible and may <br /> charge slightly from year to year based on weather conditions. The gob material will be <br /> stockpiled in rows generally running from northwest to southeast. The rows of gob will be <br /> placed in a controlled manner and overlap will be minimized so there is space between rows <br /> to allow for drainage to the southeast. Windrows were located or top of the pile and <br /> contained gob that had been Mauled out of the west drying area. <br /> The available volume of coverfill material is sufficient to meet the requirements of Mule <br /> 4.10.4(5). No coverfill was used for blending or other uses during the quarter. <br /> Maintenance work performed during the quarter include cleaning of Pond F, and cleaning of <br /> Ditch F . The culvert at curve #11 was installed, and riprap was placed in the section of ditch <br /> F4 that was dowrutting. <br /> failure of the gob pile no. 1 would probably not be a hazard to human life. The pile i <br /> located above a large flat berth. The bench is approximately 80 to 1 o-feet wide directly <br /> below the pile. Additionally, the gob pile sediment pond is located below the pile. If the coal <br /> nine waste bank failed} the material would very likely be contained on the bench below the <br /> pile and or within the gob pile sediment pond. <br /> failure of gob pile no. 2 would probably not be a hazard to human life. A residential <br /> dwelling is located over Soo-feet below pile no. 2. The piles are located above Bowie Toad. <br /> A faiIure of the piles might damage Bowie Road and the Fire Mountain Canal but would not <br /> likely impact the residential dwelling. <br /> A failure of gob pile no. 3 would not be a hazard to human life. A failure of the pile might <br /> damage the rail track below the pile, A small slip/slide occurred in February on the southern <br /> edge of the pile, no offsite damage occurred. The road at the toe of the pile was covered <br /> with gob raking it inaccessible to vehicles. <br /> -2- <br />
