摘要
为防止煤矿水害事故的发生,利用井下直流电法探测技术对水害严重的焦作矿区9个生产矿井的110多个采掘工作面进行了探测.探测结果可用于预报掘进工作面前方地质构造及其破碎带、划分采掘区岩层贫富水区域、论证工作面回采时的水害危险性并圈定易突水地段、确定放水孔位置等.探测研究成果绝大多数已得到采掘工程实践的验证,准确率达82%以上.
To prevent water-inrush, the author used the D. C. technology in more than 110 working faces in 9 mines of Jiaozuo to detect forward geological structure, plotted out water-bearing conditions in face, circled the easier water-inrush area, valuated the fatalness of water-inrush in working face and confirmed the position of water hole etc. Most of detecting results have been verified by mining practices. The veracity is over 82 %.
