摘要
为了研究综合勘探技术在矿井采空区积水探测中的应用,分析了瞬变电磁法探测采空区积水的原理,对布置4条探测线对A区域内部采空区含水性进行探测的瞬变电磁法探测方案及其探测结果进行了探讨,并对钻探技术的验证进行了分析。根据探测结果可知,采空区内部电阻率高,采空区外部电阻率低,由此可推出,A区域内部采空区没有出现积水现象。由采用钻探技术对探测结果进行验证的结果可知,瞬变电磁法探测结果准确。
In order to study the application of integrated exploration technology in the accumulated water detection of mine goaf,this paper analyzed the principle of detecting the accumulated water in the goaf by the transient electromagnetic method, and discussed the transient electromagnetic detection scheme and its detection results of detecting the water content of the goaf in the A area by arranging four detection lines, and analyzed the verification of drilling technology. According to the detection results,the internal resistivity of the goaf is high, and the external resistivity of the goaf is low, which can derived that there was no water accumulation in the goaf in the A area. The results of verification of the detection results by drilling technology show that the transient electromagnetic method has accurate detection results.
