The enrichment rules of limestone groundwater under coal bed in Wuzhai coal mine
Abstract：Focusing on the threaten by groundwater of limestone aquifer under the 15 coal floor in Wuzhai coal mine, the paper analyzed the characteristics of the limestone aquifers, studied the development characteristics and the distribution rules of karst and fractures, and pointed out the enrichment zones of groundwater. It shows that karst and fractures is strongly developed at the shallow districts and gradually weakened with the level becoming deep. The zones above the level of - 150 m is the enrichment zone of limestone groundwater, the level from -150 to -350 m is moderate, and level deep than -350 m is rather poor of limestone groundwater. According to the prospecting results, it exists several independent abnormal zone in limestone under coal floor at the level from -250 to -340 m in the western district of Wuzhai coal mine.
