采空区勘查中物探技术应用研究

Application of geophysical prospecting technology in goaf exploration

在进行矿产资源开采后,采空区没的地质会引起地表沉降、塌陷、开裂等地质灾害,因此采空区的勘查工作至关重要。为此,提出一种综合物探技术。该综合物探技术为地震勘探法、瞬变电磁法、高密度电法、地质雷达法等方法中2种或2种以上的组合。最后通过钻孔验证,证明了综合物探技术的勘查准确性。

After the mining of mineral resources,the existence of goaf will cause surface subsidence,collapse,cracking and other geological disasters,so the exploration of goaf is very important.Therefore,a comprehensive geophysical prospecting technique is proposed.The integrated geophysical exploration technology is a combination of two or more methods,such as seismic exploration method,transient electromagnetic method,high-density electrical method,geological radar method,etc.Finally,through drilling verification,the accuracy of comprehensive geophysical exploration technology is proved.
