摘 要:利用UDEC数值模拟软件对山西焦煤集团东曲矿浅埋煤层工作面开采导致的覆岩移动及裂隙发育过程进行数值模拟研究,真实反映了在工作面推进过程中覆岩移动及裂隙发育规律,得出浅埋煤层开采后直接顶和老顶的垮落步距以及上覆岩层移动规律.UDEC numerical simulation software was used to study the overlying strata movement and fracture development caused by the mining of the working face on shallow coal seam in Dongqu Mine,Shanxi Coking Coal Group.The study reflects the laws of the overlying strata movement and fracture development during the advancement of the working face and obtains the caving step distance of direct and old roof as well as the overlying strata movement after the mining of shallow coal seams.
