摘　　要：以河北省中关铁矿采空区的探测为例,利用高密度电阻率法和电阻率测深法组成的综合方法开展了探测地下采空区有效性的试验研究。充分利用高密度电阻率法信息量大、水平分辨率较高、可二维反演成像优点和电阻率测深法探测深度大、垂向分辨率高、一维反演方法成熟的优点,建立了二者取长补短,优势互补的综合探测组合模式,查明了该矿区采空区的位置及分布情况,后期钻探验证表明所采用的综合探测组合模式是行之有效的。Taking the exhausted area of Zhongguan iron mine in Hebei province for an example,this paper uses the high density resistivity and the electric sounding methods to do an effective experiment of detecting the exhausted area.It makes full use of high density resistivity method with a large amount of information,high horizontal resolution and two-dimensional inversion imaging.The electric sounding method has the advantages of exploring great depth,high vertical resolution and one-dimensional inversion method.It has established a very good combined model and detects the position and distribution of the exhausted areas in the iron mine.Finally,it achieves a good result.
