摘要
卧龙湖煤矿8102回采工作面为软厚煤层大采高工作面,采用数值模拟、相似模拟与现场监测相结合的方法对其上覆岩层运移规律进行了分析研究,得出了裂隙带、垮落带高度、裂隙演化及亚关键层破断规律。
Coal face 8102 in Wolonghu mine is characterized by soft thick coal mass and great mining height, Using numerical simulation, physical simulation, and field monitoring, analyzed the movement characteristics of the overlying strata, acquiring the height of the fractured zone and caved zone and understanding the characteristics of fracture evolution and the inferior key strata failure.
