矿井综合物探技术在南方煤矿探测岩溶突水通道中的应用

在我国南方多水患矿井治理中,一般采用矿井综合物探技术探查其岩溶突水通道,以便采取防、堵、疏、排、截等措施治理其水害。为了查明某矿井矿井井下＋352水平、＋270水平巷道内出水岩溶通道的具体走向、位置及大小,在其地表及巷道内共布置物探测线10条,其中4条地面测线,6井下测线。从高密度电法探测所得的电阻率断面图上看,其存在4个明显的低阻异常区。据此探测结果,结合地质资料进行分析,共找出5条岩溶导水通道。地质雷达探测结果对比,二者的探测结果较吻合。

Application of Mine Integrated Geophysical Prospecting Technology on Karstic Water Bursting Channel Detection in Southern Coalmines

In harness of mine water disaster frequent southern China coalmines, mine integrated geophysical prospecting technology is usually used to detect karstic water bursting channels, in order to harness water disaster with measures of prevention, stopping, dewatering, drainage and damming. To find out specific strike, position and scope of water conducting karstic channels in underground ＋352m, ＋270m levels horizontal roadways in a coalmine laid out 10 prospecting lines, of which 4 on surface, 6 underground. On the resistivity section from high density electric surveying, 4 low-resistivity anomalous areas are existed obviously. Based on the result, combined with geological data, 5 karstic water conducting channels have found, they are tally with geologic radar detected results.
