寺家庄煤业15116工作面开采地表沉陷规律研究

Study on mining surface subsidence law of 15116 working face of Sijiazhuang Coal Industry

为保护阳煤集团寺家庄煤业15116工作面矿区及周围的建筑物、农田及人员的安全,对该工作面回采期间地表位移和沉降的规律进行研究。通过理论分析及数值计算确定具体的测站布置参数,对观测及对统计结果的整理,获取15号煤层开采上覆岩层的岩移规律和相关参数,为15号煤层采动地面保护提供依据。

In order to protect the safety of buildings, farmland and personnel in the mining area of 15116 working face of Sijiazhuang Coal Industry of Yangquan Mining Group, the law of surface displacement and settlement during the mining of the working face was studied. Through theoretical analysis and numerical calculation, the specific station layout parameters were settled, the observation and the statistical results were sorted out, and the rock movement law and related parameters of the overlying strata in No. 15 coal seam mining were obtained, which provided a basis for the ground protection of No. 15 coal seam mining.
