矿井综合物探技术在隐伏含水构造超前探测中的应用

摘要

In order to accurately detect the concealed water-bearing structure in front of a heading face in a coal mine, a comprehensive geophysical prospecting technology including the mine long-range acoustic detection method and the mine D. C. electrical method was used for the advance detection of the concealed water-bearing structure in front of the heading face in Zhaogu No. 2 Mine of Jiaozuo Coal Industry ( Group) Co. , Ltd. The results showed that using the long-range acoustic detection method can better detect the position and scale of the concealed geological anomaly in front of the heading face and using the mine D. C. electrical method can identify the water abundance of the structural anomaly. The comprehensive application of two geophysical prospecting methods can make up each other’s deficiencies and verify each other by comparison, in addition, it not only improved the prediction accuracy, but also realized the detection of the structural anomaly and the detection of its water abundance.%为了准确探测煤矿掘进工作面前方隐伏含水构造，采用矿井远距离声波超前探测法和直流电法的综合物探技术，对焦作煤业集团赵固二矿掘进巷道隐伏含水构造进行了超前探测，结果表明：远距离声波超前探测法可以较好地探测掘进工作面前方隐伏地质构造异常体的位置和规模，井下直流电法可以查明构造异常体的富水性，综合利用这两种物探技术能够做到取长补短、对比验证，可在提高预报准确率的同时兼顾构造探测和富水性探测。
