摘要
针对地下煤层开采导致工作面所在地表区域出现变形甚至塌陷的问题,为了进一步减少煤层开采造成的上述问题,以某矿21132综采工作面为例,在对其顶底板地质条件分析的基础上,通过构建走向和倾向两个观测线对其地表变形进行实测的基础上,综合采用数值模拟计算模型对该工作面的垂直位移和垂直应力进行模拟分析,为地表变形的控制提供理论指导。
In response to the problem of deformation or even collapse of the surface area where the working face is located due to underground coal seam mining,in order to further reduce the above-mentioned problems caused by coal seam mining,taking the 21132 fully mechanized working face as an example,based on the analysis of the geological conditions of its roof and floor,two observation lines of strike and dip were constructed to measure the surface deformation,a comprehensive numerical simulation calculation model is used to simulate and analyze the vertical displacement and vertical stress of the working face,providing theoretical guidance for controlling surface deformation.
