| 摘 要： | 根据煤层开采后影响上覆岩层及地表而产生移动和变形的时间的变化关系定性分析采空区稳定性,而且采用FLAC3D模拟了在施加地面建筑载荷后地表变形情况,确定了采空区需要处理的范围;依据建筑物荷载集度及其重要程度,采用了不同注浆处治对策.通过对采空区上覆岩体的沉降和建筑物沉降监测数据的统计分析,评估了处治效果.

| Abstract: | In this paper, the analysis of waste cave stability accord to Changing in the relationship between overlying rock ＆ surface movement deformation and time, when the coal seam was mined, And simulation ground deformation using of FLAC3D after ground building load on, Determine the scope needed to deal with ; On the basis of building load size and important degree, Using different grouting treatment countermeasures. Through monitoring data analysis about the goal of overlying rock subsidence and building subsidence , Evaluation of the treatment effect |
