摘要
根据斜沟煤矿13号煤层赋存条件,运用FLAC3D数值模拟,主要研究了底层4.5m大采高综放全厚开采14.6m特厚煤层工作面煤壁前方支承压力作用及顶煤和顶板垮落特征等特征,对类似条件工作面的生产具有一定的指导意义。
On the existence conditions of No.13 seam of Xiegou mine and the application of FLAC3D numerical simulation, the study analyzed front support stress of working face during the full-seam mining with large mining and 4.5m bottom height for 14.6m very thick seam, top coal and caving characteristics, which is beneficial the similar working faces.
