针对平顶山矿区吴寨矿-5煤层开采受底板灰岩水威胁的现状,分析了-5煤层底板灰岩含水层的基本特征,研究了岩溶裂隙的发育特征和分布规律,查明了富水分区.研究表明,灰岩含水层浅部岩溶裂隙较发育,随着深度增加,岩溶裂隙发育程度逐渐减弱.标高在-150m以上为灰岩地下水强富水区;-150~-350m为中等富水区;-350m以下为弱富水区。根据物探结果,在矿井西翼-250~-340m水平,煤层底板灰岩存在多个相互独立的异常区.

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.
