Abstract: The research on mining failure depth of coal seam floor is of great significance to the prevention and control of floor water damage and gas drainage. It is one of the most important topics in research of coal mining. A number of scholars have carried out research on it and made remarkable achievements. Based on the work of predecessors, this paper summarizes the research progress of calculation methods of mining failure depth of coal seam floor, introduces four calculation methods of mining failure depth of coal seam floor, including theoretical calculation, on-site detection, numerical simulation and similar material simulation, systematically combs the principle, the calculation process of each research method and the work of predecessors, and the development prospect of the four methods is prospected, the purpose is to provide some reference for related research.
