Study on Technology of Exploration of Mine Goaf Water Accmulated Area

针对煤矿采空区透水事故频发的问题,采用瞬变电磁法对采空区分布及其积水情况进行物探。确定瞬变电磁法在正常煤层、采空区和积水区的视电阻值范围,圈定采空区边界及范围效果好,分辨率高,提高了采空区及其积水情况的探测效果。

According to problem of the mine water inrush frequently occurred in mining goaf, the transient electromagnetic method is apply to study the exploration on the mining goaf attribution scope and the accumulation conditions. make sure the transient electromagnetic method in the normal seam, goaf water accumulated area is determined and be applied to guide the explanation, and an effect of the set goaf boundary and scope would be good and the resolution would be high.The survey effect of the goaf and water accumulation condition could be improved.
