摘要
为了研究煤矿不同条带充填工作面开采顺序引起的上覆岩层移动变形的影响,以刘东煤矿西510采区为工程背景,采用FLAC3D数值模拟,模拟了2种充填工艺下的上覆岩层应力分布、塑性区范围以及位移变化。采用相似材料模拟试验的方法,分别对2种充填工艺下上覆岩层的应力与位移数据进行监测。
In order to study the influence of different coal strip filling working face mining sequence on the overlying strata movement and deformation, taking Liudong coal mine, west 510 mining area as an engineering background. The stress distribution, plastic zone and displacement of the overlying strata in two kinds of filling process are simulated by FLAC^3D. Similar material simulation monitor the stress and displacement data of the overlying strata.
