摘要
通过对采煤工作面水地质条件及物探资料分析排除了奥陶系奥灰承压含水层对工作面正常生产的威胁,工作面出水后对突水因素进行分析并及时取水样进行水质化验,认为底板局部砂岩含水层与L7灰岩含水层是造成工作面水灾危害的主要原因,同时提出了防治水对策。
Through analyzing the geological conditions and geophysical prospecting data of the coal face,the threat of Ordovician limestone confined aquifer to the normal production of the face is ruled out.The water inrush factors are analyzed after the face watered and water samples for water quality are tested timely.The result shows that the sandstone aquifer in part of floor and the L7 limestone aquifer are the main reasons for the face flood hazards,and the water control measures are put forward too.
