摘要
新景煤矿9114回风巷为大断面巷道,地质条件较为复杂,巷道围岩稳定性较差。采用现场监测、理论分析、数值模拟的手段对该巷围岩的破坏原因进行了研究,对原支护方案进行了优化。现场监测结果表明,9114回风巷的围岩稳定性得到了显著提高。
The 9114 return air roadway in Xinjing Coal Mine is a large cross section roadway with complex geological conditions and poor surrounding rock stability.The failure causes of the surrounding rock of the roadway are studied by means of on-site monitoring,theoretical analysis and numerical simulation,and the original support scheme is optimized.The field monitoring results show that the surrounding rock stability of the 9114 return air roadway has been significantly improved.
