摘要
Abstract
To accurately invert the predicted parameters of surface subsidence near goaf, the normal subsidence law of surface after mining and the prediction method of residual subsidence near goaf are analyzed, and the near goaf is equivalent to a small working face with variable mining height to invert the parameters of probability integral method. A parameter inversion method based on probability integral method for surface subsidence is proposed. The surface subsidence curve predicted by the probability integral parameter obtained by this method is in good agreement with the measured curve, which provides a feasible method for the surface probability integral parameter inversion affected by adjacent goaf.关键词
