摘　　要：根据云冈煤矿8615^-1大采高工作面煤层赋存情况和开采技术条件,构建FLAC^3D数值模型,通过设置边界条件,研究了厚煤层大采高工作面随着开采距离不断增加采场上覆岩层的应力场、位移场和围岩破坏规律。研究结果能够指导厚煤层大采高工作面开展采场围岩控制。According to the coal seam occurrence and mining technical conditions of 8615^-1 large mining height working face in Yungang Coal Mine,the FLAC^3D numerical model is constructed,the stress field,displacement field and surrounding rock failure law of overlying strata in large mining height working face with thick coal seam are studied.The results can be used to guide the control of surrounding rock in large mining height working face of thick coal seam.
