保德煤矿底板隔水性分析和防治水措施
|
摘要
面临底板突水危险的矿井,在正常掘进和回采过程中,要充分利用煤层底板到奥灰水承压含水层之间的隔水层的隔水性能,保德煤矿在开采8#、11#煤层时,同样面临底板奥灰水威胁,因此应针对底板隔水层的隔水性进行分析,提出"带压开采"的防治水路线,制定底板奥灰水防治水措施。
Mines facing the danger of floor water inrush, during normal excavation and mining, it is necessary to make full use of the water isolating of the aquifer between the coal floor and the ordovician limestone aquifer. When Baode coal mine is mining 8 # and 11# coal seams, facing the threat of ordovician limestone water on the floor, put forward the water control route of " mining under pressure",establishment of water control measures for ordovician limestone water on floor
