矿井充水因素分析及水害防治措施

The Mine Water Filling Factors Analysis and the Water Disasters Prevention and Control Measures

通过对庄旺煤矿矿井充水因素分析,得出结论:该矿充水水源包括地表水、2号煤层上覆砂岩裂隙含水层、采空区积水、奥灰水等4个方面;矿井充水通道包括导水断层、岩层裂隙、采空导水裂隙带、封闭不良的钻孔等4个方面;本井田主要水害是来自矿井采空区积水、古空区积水和周边矿井采空区积水。基于以上结论,采取了相应的矿井水害防治措施。

The analysis on Zhuangwang Coal Mine＇s water filling factors comes to the conclusions of that the mine＇s water filling sources include the surface water, No.2 coal seam＇s overlying sandstone fracture aquifer,goaf water and Ordovician limestone water, the mine＇s water filling channels include the water flowing fault, fracture in rock stratum,goaf＇s water flowing fractured zone and improperly closed drill-hole; and the main water disasters in this mine comes from the mine＇s goaf water,old mine goaf＇s accumulated water and surrounding mine＇s goaf water. And based on the abovementioned conclusions, the corresponding measures are adopted for the prevention and control of mine＇ s water disasters.
