| 摘 要： | 利用双频激电法在山西沁源嘉元煤业有限公司已知采空区进行实地探测试验,通过对探测数据的整理与分析得知:在未充水的采空区探测得到较高的视电阻率和较低的视幅频率,能够精确的反映地下采空区的位置.结果证明了利用双频激电法探测煤矿地下采空区是可行的.

| Abstract: | We have implemented experiments on the known gobs in the Jiayuan Coal Corporation in Qinyuan of Shanxi using the method of dual frequency induced polarization.Through reorganising and analysising the data,we got that higher apparent resistivity rate and lower apparent ampli- tude-frequency rate exist in the gob without water by detection and the position of the gob underground was precisely given.The result turned out that the double frequency induced polarization method to detect the coal gob underground is feasible. |
