摘　　要：从可控源音频大地电磁法工作原理、采空区地球物理前提、探测设备及参数设置、探测现场布置、资料分析、探测结果及钻孔验证情况等方面,介绍采用可控源音频大地电磁法对某煤矿采空区的探测实例。经过钻孔验证,采空位置与检测结果相吻合,说明可控源音频大地电磁法探测煤矿采空区是可行的。This paper deals with an example of detecting coal mine goal by using controllable source audio magnetic technique （CSAMT）. The following aspects are discussed：the working principle of CSAMT,the geophysical premise of detecting coal mine goaf, the equipment and its parameter setting, the working field layout and the data analysis. The result of the study was verified by drilling. Drilling verification shows that the detecting result is coincident with the coal mine goaf. It is thus held that the CSAMT is effective in detecting coal mine goal.
