摘　　要：通过对杉树堡地面塌陷进行调查,掌握采空区塌陷的主要特征;采用概率积分法模型计算矿井矿层开采后产生的地表移动变形最大值,分析浅部开采和井巷道顶板塌落引发该矿地面塌陷的主要影响因素。Based on the investigation of the surface collapse of Shanshubao,the main characteristics of the collapse of the goaf are mastered;the maxi mu m value of the surface move ment and defor mation caused by the mining of the mine sea m is calculated by using the probability integral method model,and the main influencing factors of the surface collapse caused by the shallow mining and the roof collapse of the mine roadway are analyzed.
