【摘要】 以晋煤集团晋圣亿欣煤业XV1310回采工作面地表岩移观测站的建立为例,通过对该工作面地表岩移观测站的观测,获取了观测各期的下沉、水平移动、倾斜、曲率、水平变形值等数据,通过数据分析获得XV1310工作面开采过程中的动态沉陷规律、详细的地表移动时间过程及15~#煤层岩层移动参数,可指导该矿区进行"三下"开采和保护煤柱的留设。更多还原

【Abstract】 Taking the example of the construction of the surface rock movement observation station of the XV1310 mining face of JinshengYixinMining Co.,Ltd.,Jincheng Coal Mine,the surface rock movement observation station is used to obtain various observation data,including sinking,horizontal movement,tilt,curvature,and horizontal deformation in each period.Then,based on the data analysis,the dynamic subsidence law in the mining process,the detailed surface movement time course,and the movement parameters of No.15 coal and rock stratawere obtained,which could guide thethree-under mining and retention of protective coal pillars.更多还原
