摘 要:宁武煤田北部平塑矿区煤矿开采受奥灰底板承压水威胁,由于奥陶系灰岩含水层富水性强、水压高、补给水源区域广、隔水层相对薄弱、区内断裂构造及陷落柱发育,致使该区煤层开采受奥灰水严重威胁。煤层开采时,对断层及陷落柱导通奥灰水的危险性分析与研究显得极为重要。文章结合担水沟煤矿9101工作面实际情况,做一些浅析。In coal mining of Pingshuo mine area in the northern of Ningwu Coalfield, Ordovician limestone floor with the confined groundwater have a serious threat. The Ordovician limestone aquifer which is rich in the water and have the high water pressure, the wide water supply , the weak impermeable layer with the fault structure and the subsided column are common , so the mine in this area is faced with a serious threat. The risk research on which the faults and subsided column conduct the Ordovician limestone wa ter are extremely urgent. This paper have a simple analysis in combined with the fact of the 9101 work face in Danshuigou Coal Mine.
