| 摘 要： | 运用双频激电法在煤矿火区做了探索性的试验,并辅以活性炭测氡法,两种方法的结果吻合较好,得到了钻孔验证。结果表明:煤矿火区上方双频激电法异常反应非常明显,视幅频率数值是正常区背景值的2倍,呈高视幅频率特征;而视电阻值则是正常区背景值的50%~75%,呈低视电阻率异常特征;同时在火区上方出现高氡值异常,且氡值波动较大。试验证明,运用双频激电法可探测不同埋深的煤矿火区,是值得推广的。该方法还可用于对煤矿火区范围的动态监测。

| Abstract: | A tentative study was conducted in the coal mine fire zone by using the dual-frequency IP method with the assistance of radon measurement.The results of the two methods were well consistent with each other,which was substantiated by exploratory boring.It is shown that at the top of the coal mine fire zone there exists a very obvious abnormal reaction when the dual-frequency IP method is used.The apparent amplitude-frequency rate of the normal value is 2 times that of the background value zone,showing a high... |
