摘要
介绍了矿井直流电法勘探的工作原理,研究了井下巷道有限施工条件下探测矿井水的方法,证明了矿井直流电法勘探技术在探测巷道掘进头前方、巷道顶底板及巷道侧帮等方向断裂水、老空水的有效性。在此基础上,总结了井下直流电法技术应用中需注意的若干关键问题。
The working principle of mine DC method is introduced, methods of detecting mine water are studied under the limited circumstances in the underground roadway, it is proved that detecting water of the fault zone and old kiln by the mine DC method is effective in the tunneling front, roof and floor of the roadway, two walls of the roadway. On this basis, several main key issues which should be taken care of are summed up in the mine DC method application.
