摘　　要：本文以某煤矿开采形成的采空区范围为研究区,在搜集煤层赋存情况、现有采空区分布情况的基础上,选取岩层合理的物理力学指标,利用比较常用的概率积分法、数值模拟法对采空区的下沉值、水平变形、最大地表竖向变形等进行预测模拟,从而预测研究区地表变形情况。煤矿采空区地表变形的预测,是工程建设场地适宜性预测评估结论的重要依据。In this paper,the author takes the goaf area formed by a certain coal mine as the research area,on the basis of collecting coal seam occurrence and existing goafs distribution,selects the reasonable physical and mechanical indexes of rock layers,using the common probability integration method and numerical simulation method to predict the subsidence value,horizontal deformation and maximum surface vertical deformation,so as to predict the surface deformation in the study area.The prediction of surface deformation in coal mine goaf is an important basis for the prediction and evaluation of the suitability of engineering construction site.
