应用直流电法仪在井下进行了工作面巷道底板电测深和掘进头超前探测，查清了工作面底板含水层的富水性和掘进头前方的地质构造及含水情况。目前，大部分探测结果已得到生产实践的证实。
The method of direct current method was used to carry out electrical sounding of underground roadway and advanced detection of driving head in underground working face. The water-bearing property of aquifers in working face and the geological structure and water content in front of driving head were ascertained. At present, most of the exploration results have been confirmed by the production practice.
