摘　　要：岩溶地区岩溶管道及断层破碎带的存在导致矿山开采过程中易发生涌水突泥现象,对人民群众的生命财产造成严重威胁。采用广域电磁法、可控源音频大地电磁法和瞬变电磁法开展矿区岩溶发育及深部构造分布特征的探测工作,圈定了岩溶发育区及断层破碎带的规模及分布情况。通过剖面解译成果对比及钻探验证,对比分析每种勘探方法在矿区隐伏探测中的应用效果,为岩溶塌陷灾害防治及矿山开采方案设计提供科学依据。The existence of karst pipelines and fault fracture zones in karst areas leads to the phenomenon of water and mud inrush during mining,posing serious threats to people s lives and property.In this paper,the wide field electromagnetic method(WFEM),controlled source audio-frequency magnetotelluric method(CSAMT)and transient electromagnetic method(TEM)were used to detect the karst development and distribution characteristics of faults in the mining area,and the scale and distribution of karst development areas and fault zones were delineated.By comparing the profile interpretation results and drilling verification,the application effect of each exploration method in the hidden detection of mining area were analyzed,which provided scientific basis for the prevention and control of karst collapse disaster and designing mining plans.
