This paper Utilized the controlled source audio magnetotelluric method(CSAMT)to research the karst collapse distribution of JiLi village of GuangXi province LaiBin city.The study made a result that the karst collapse of JiLi village distributed along with the fault zone,and predicted sevrel hidden Fault-piping karst collapse hazards.CSATM can be broadly delineated strong Karstifica-tion region caused by fault and in order to provide a reliable basis for finding this type of collapse. However,it should be combined with other geophysical methods to detected the location,depth,size,nature of filling of the underground buried karst collapse.
