摘　　要：随着我国西部煤炭资源的勘探,煤炭资源的开发逐步向西部转移,西北降雨相对较多地区的矿井水害慢慢凸显出来,其具有隐蔽性、突发性。为查明研究区矿井的隐蔽致灾水害状况,应用地面瞬变电磁法进行矿井水害探测,结合已有的地质和水文地质资料,取得了较好的探测效果;探测结果与已知的采空区积水区对应较好,同时基本探明了B_9煤层顶板西山窑组孔隙裂隙含水层的富水区域,也证实了其与第四系含水层、烧变岩含水层的水力联系,为矿井生产及水害防治提供了有力依据。With the exploration of coal resources in the west of China,the exploitation of coal resources is gradually transferred to the west,and the mine water disaster in the areas with relatively more rainfal in the northwest gradually emerges,which is concealed and sudden.In order to find out the hidden disaster-causing water hazard of the mine in the study area,ground transient electromagnetic method is used to detect mine water hazard.Combining with the existing geological and hydrogeological data,good detection effect is achieved.The detection results correspond well with the known water logging area o mined-out area.Meanwhile,the water-rich area of the porefissure aquifer of Xishanyao formation in the roof of B_9coal seam has been basically explored,and the hydraulic connection between Xishanyao formation and the quaternary aquifer and the burned rock aquifer has been confirmed,which provides a strong basis for mine production and water hazard prevention and control.
