Abstract: The main purpose is to find out the seepage sedimentation mechanism of soil in mine, and analyzes the relation between soil sedimentation and shaft rupture. In this paper, the simulation experiment of ground water seepage and soil sedimentation is conducted. The seepage sedimentation mechanism of soil is analyzed. The relative non-compression zone in soil around shaft is revealed. The formation reason and variable laws of slide negative friction are studied. Based on the analysis of a lot of the fracture shafts in China, the relation between ground water seepage and shaft rupture is investigated. The results show that the time of shaft rupture can be predicted by analyzing the level of groundwater around shaft.
