摘要
为了准确反演受到邻近采空区影响的地表沉陷预计参数,通过分析工作面开采后地表正常下沉规律与邻近采空区残余沉降量的预测方法,将邻近采空区等价成变采高的小工作面开采来进行概率积分法参数反演,提出了邻近采空区影响的地表沉陷概率积分法参数反演方法。利用该方法求取的概率积分参数预计得到的地表下沉曲线与实测曲线比较吻合,为邻近采空区影响的地表概率积分参数反演提供了可行方法。
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.
