摘　　要：本文在分析求取概率积分法预计参数的方法基础上,基于潞安矿区王庄煤矿地表移动观测站实测资料,利用Matlab软件中非线性最小二乘拟合函数,绘制了各类地表移动变形拟合曲线,得到了概率积分法预计参数。同时,进行了地表移动变形的实测最大值与拟合值的分析比较,评定了其拟合精度。结果表明,用该方法求取概率积分法预计参数方便可行、参数求取准确、拟合精度高,具有较强实用性和可操作性。In the paper, based on the methods and procedures of obtaining prediction parameters of probability integral method, according to the observation data from observation station, least-square fit- ting function in Matlab software was used, relevant fitting program was written, various fitting curves of the surface movement and deformation were drawn, then the prediction parameters of probability integra- tion method ere obtained. At the same time, the observation values and fitting values of the surface move- ment and deformation were analyzed and compared, the fitting precision was evaluated. The results showed that the method was convenient and feasible, its fitting precision was high, the obtaining parame ters was correct, which proved its vadality.
