摘要
以内蒙古孙家壕矿为依托,通过理论分析、FLAC3D数值模拟,针对9#煤层节理化破碎围岩巷道支护开展了研究,通过比较3种支护方案,得出了锚喷能够对破碎围岩巷道进行有效支护,对于强风化岩层下的软岩支护以及类似地质情况矿井支护具有一定的参考价值。
Inner Mongolia Sunjiahao mine is studied by theoretical analysis and FLAC 3D simulation. In order to compare three kinds of supporting schemes,the easily broken No.9 coal roadway is supported. Finally anchor-plate retaining is proved to be effective to soft rock roadway support .It has certain reference value for soft rock support under strong weathering rock layer and mine support in similar geological conditions.
