摘　　要：本文以河南超越煤业公司伦掌煤矿新建1．20Mt／a煤炭开采（井工开采）项目土地复垦为例，根据本项目的特点和开采时序，划分了预测评价单元和时序。采用概率积分法，确定了地表移动变形预测参数，测算出各时段的地表移动与变形最大值预测结果。根据塌陷预计变形情况，建立对应的地表塌陷损毁程度评价指标体系，最后得到各地类的塌陷损毁程度。Taking 1.20 Mt/a New Coal Mining Land Reclamation Project in Lunzhang Coal Mine as an Example, this paper divides the prediction evaluation into units and sequences according to the project characteristic and mining sequences, and it decides the surface movement deformation prediction parameters by probability integral method. It also measures maximum prediction of surface movements and deformations in different periods. Based on subsidence deformation prediction, this paper establishes the corresponding evaluation index system of surface subsidence damage degree, and finally gets subsidence damage degrees of different grounds.
