直流电法仪探测煤矿井下水情中异常区的实践

The Practice of Determining the Abnormal Area in the Detection of Underground Hydrologic Information of Coal Mine with DC Electric Device

通过YDZ(A)直流电法仪在探测山西孝义金晖万峰煤矿井下水情中异常区的工作实践,找出了该矿物探结论准确定性的相关参数。并将低阻视电阻率作为主要的考虑因素,对该矿首采工作面按照不同低阻视电阻率区段对物探资料进行了分析总结,以期为其他矿运用YDZ(A)直流电法仪提供借鉴。

Through the practice of using DC electric device YDZ（A）to determine the abnormal area in the detection of underground hydrologic information of Jinhui Wanfeng Coal Mine in Xiaoyi City of Shanxi Province, this paper finds out some parameters related to the accurate characterization of geophysical conclusions of this coal mine, and taking the low resistance apparent resistivity as a major consideration, and analyzes and sums up the geophysical data based on different sections with low resistance apparent resistivity on the first mining face in Jinhui Wanfeng Coal Mine for providing some references for other coal mines in using DC electric device YDZ（A）.
