Abstract: This paper compartmentalized tectonic evolution as the main framework, combining with the sedimentary burial history and geometry morphology of collapse column, this paper expounds the formation process of karst collapse column in Fangezhuang coal mine. The results showed that the reason of the development of sinkhole is the superposition of three periods of tectonic movement in this areas: North-east directional failure in the Late Yanshanian-Early Himalayan that leads to the development of groundwater flow zones through Kaiping coalfield, were the decisive conditions of the development of karst sinkhole; At the same time, according to the distribution of collapse column in mining area, we have studied the influence factors for specific location of collapse column, The possibilities of southeast area is high for the development of un-mining area by studying Tectonic curvature theory and ancient runoff condition. It provides a new train of thought for the prevention and prediction of karst collapse.
