在对多种地球物理勘探方法介绍与对比的基础上,以赤峰市某煤矿采空区勘查为例,采用可控源音频大地电磁测深法、瞬变电磁法和三维地震物探方法,进行了应用研究,并通过钻探进行了验证.结果表明:以三维地震法为主、以可控源音频大地电磁测深法和瞬变电磁法为辅的综合物探方法在资源型城市采空区勘查中较为可靠和有效,可在其他资源型城市采空区识别与鉴定中予以推广应用.
This paper introduced and a majority of geophysical exploration methods, chose controlled source audio frequency magnetotelluric method, transient electromagnetic method and three dimensional seismic method was used to detect the coal mine goaf in Chifeng and then the results were confirmed through drilling verification then Results shows that it is reliable and efficient to integrate these methods and techniques on prospecting mine goaf.Thus,this scheme should be
