| 摘 要： | 地下煤层采出后采空区顶板在重力场及其上覆岩、土体的作用下会沿着层理面法线方向移动。随着工作面推进,顶板岩层端部开裂,在岩层中部开裂还很少的情况下顶板岩层整体切断垮落。文章根据不同时间所测得的各类地表变形的现状特征,分别做出每个观测对象对应观测时间井下开采与地表变形现状的二维坐标关系图。

| Abstract: | The underground coal produced in the gravitational field and its roof after overlying rock and soil under the action of along the bedding face normal direction.Along with the working face advances,roof strata termination craze,in central craze is little rock under the condition of the whole roof strata baggy fell off.According to different time measured surface deformation of the status quo,characteristics,respectively,make each observation object corresponding observation time underground mining and ground... |
