摘　　要：在采空区残余沉降的预测中,概率积分法参数的选取至关重要。但它并没有规律可循,只能根据经验。为较好地解决这一问题,提出了一种求取概率积分法参数的简便预计模型,归纳了参数的选取规律,建立了预计模型,导出了预计公式。同时结合某矿区的实测资料,按上述方法求得了预计参数,进而对另一矿区的残余下沉进行了预计与比较,取得了良好的预测效果,证明了该研究方法具有一定的普遍适用性和正确性。In predicting the residual residence of mine goal, the selection of probability integral parameters is of great importance. There is no rule to follow and all will be made according to your experience. To solve this issue, the paper proposes a simple prediction model for selecting the parameters of probability integration, summarizing the parameter selection law and giving a prediction formula. Based on the practically measured data of a mining area, prediction parameters were selected according to the said method. Prediction was then made for the residence subsidence of another mining area. The comparison of the predicted result with the practically measured data shows a good conformity, illustrating that this method is u- niversally applicable and valid in certain scope.
