榆神矿区南部中小煤矿突水危险性研究

Study on Water Inrush Danger of the Small and Medium-sized Coal Mine in the South of Yushen Mining Area

论述了榆神矿区部分中小煤矿突水实例,分析了矿井突水的地质、水文地质条件,认为,榆神矿区萨拉乌苏组含水层厚度大,富水性强,煤层埋藏浅,煤层开采后产生的冒落带、裂隙带发育到萨拉乌苏组含水层底部,从而引起突水灾害。本文提出了矿井突水预测的思路和方法,认为应该加强矿井水文地质条件研究,开展水文地质补充勘探,查明水文地质条件,做好防治水工作,减少矿井涌水量,保护萨拉乌苏组含水层结构完整性。

It is based on some of the small and medium-sized coal mine water inrush in Yushen mine area,analyzes the geological of mine well water inrush,the hydro-geological conditions.We think the aquifer thickness of Salawusu group is large,rich water,coals buried in shallow,and after coal seam exploitation,the caving zone,the fracture zone development to the bottom of the aquifer of Salawusu group which cause to sudden water-related disasters.The article puts forward some ideas and methods for mine well water inrush prediction,meanwhile,strengthens to study the well hydro-geological conditions,promotes the hydro-geological recharged investigation and find out the hydro-geological condition in order to do well in controlling water inrush,reducing the mine discharge,at last protects the Salawusu aquifer structure integrity.
