摘要
介绍了矿井直流电法超前探测技术的原理与方法,并以晋城凤凰山矿北翼探巷矿井直流电法探测为例,分析了矿井直流电法在探测巷道前方岩层富水区中的应用。通过井下探放水钻孔及实际揭露资料验证,该方法探测采掘工作面前方富水位置和范围是非常有效的物探方法之一,能为井下水害预报和防治提供可靠依据。
In this paper,the principle of mine DC electrical method is introduced. And through the application examples of the Mine DC Electrical Method detection of the survey tunnel in Feng huangshan Mine, the author analysed the application in detecting full of water area both ahead of the tunneling and the roof. Practices demonstrate that the method is an effective means to detect he position and extent of mine water ahead of the tunneling and the roof. It also provides reliable basis for prediction and prevention of mine water disasters.
