Abstract

In order to solve the problem that it is difficult to evaluate the derivative disaster of coal mining in loess gully region of northern Shaanxi, the method to determine the subsidence coefficient in the parameter of probability integral prediction was put forward; the evaluation index of coal mining derivative disaster was determined, including maximum surface subsidence, slope stability and fracture development; based on the probabilistic integral method to predict surface movement, an evaluation method of coal mining derived disaster in loess gully region of northern Shaanxi was presented. The results show that the evaluation method is reliable and the research results can provide scientific basis for the prevention and control of coal mining derived disasters in the loess gully region of northern Shaanxi.
