Abstract： In this paper, the No.2120(4) face of Fangezhuang Mine was taken as the research object, and the research was carried out from the mining preparation stage, tunneling stage, before mining and during mining of working face. Through the use of a series of advanced means, such as numerical simulation, transient electromagnetic, radio pit penetration, microseismic monitoring, the safe mining of working face was guaranteed from each stage of working face mining. The theoretical system of water prevention and control technology for safe mining in karst collapse column development area was formed, which provided theoretical and technical support for safe mining in collapse column development area.
