摘要
在煤矿水害问题中,利用瞬变电磁法研究煤矿的底板水、顶板水、断层或陷落柱特征,已经有很多成功的案例;但是在金矿水害中的应用,尚未发现成功的案例.目前,在生产实践中,瞬变电磁法在煤矿水害资料解释还停留在利用晚期视电阻率近似处理、解释的水平.金矿水害数据采集位于深部采场,需要全空间瞬变电磁资料解释技术.基于以上背景,介绍利用反函数原理计算的全空间全域视电阻率成像,对金矿水害探测的瞬变电磁资料进行处理解释.研究发现:该解释方法不仅计算速度快,且精度满足要求,方便实测数据的快速处理.同时能够去除晚期视电阻率成像在早期、过渡期出现的假异常;通过钻孔验证和开挖,证明该成像解释方法对金矿水害防治,效果非常明显.
In the coal mine water problems, there have been many successful cases of using transient electromagnetic method to study the characteristics of coal mine floor water, roof water, fault or collapse column. However, in the application of gold mine water damage, we have not been found successful cases yet. At present, in production practice, transient electromagnetic method in the coal mine water damage data interpretation still remain in the use of late-time apparent resistivity approximation to the level of interpretation gold mine water damage data acquisition is located in deep stope. it need full space transient electromagnetic data interpretation technology. Based on the above background, the full-space apparent resistivity imaging calculated by using the principle of inverse function is introduced to deal with the transient electromagnetic data of gold mine water damage detection. The study found that this method of interpretation, not only calculating speed, accuracy and meet the requirements to facilitate the rapid processing of measured data. At the same time, it can eliminate false anomalies appearing in the early stage and the transitional stage of apparent resistivity imaging. Through borehole verification and excavation, it proves that the imaging interpretation method is very effective for the prevention and control of gold mine water damage.
