| Abstract: | The failure height of overburden rock is of great significance to the prevention and control of gas and water disasters in coal mines. This paper discusses and analyzes the space form of rock failure, the failure mechanism of overburden rock and the research method of overburden failure in detail. At the same time, it puts forward the technical problems existing in the testing method of overburden failure height at present, and aims at the existing problems at present. The development trend of similar simulation method, field test method, empirical formula method and numerical simulation method are put forward. |
