This paper discusses the correctness and feasibility of establishing nonlinear subsidence theory based on the properties of rock mass and the nature of mining subsidence. The author summarizes the large amount of experiments, field surveys, studies and achievements made by the author in recent years on nonlinear subsidence : Non-linear failure characteristics of mining rock mass, Dam age effect of mining subsidence, fractal fracture network and evolution law of mining rock mass, synergistic effect and self-organization process of mining subsidence, catastrophic mechanism of mining strata splitting, mining Fractal interface effect of dynamic fault activation and “S” fractal growth law of surface subsidence; and put forward the academic thought of establishing a prediction model and prevention and control measures based on the law and rule of non-linear subsidence of mining, and nonlinear subsidence
