摘　　要：针对常村煤矿2101工作面巷道底板变形量大的问题,通过FLAC^3D数值模拟分析,得出巷道的底板移近量数值和现场监测底板移近量几乎保持一致,且由巷道塑性区分布,可知底板破碎程度较大。基于此,提出在现有支护体系下,补充"反底拱+注浆+锚杆"的底板支护体,对巷道底板进行加固。In view of the problem of large deformation of the roadway floor in 2101 working face of Changcun coal mine,through FLAC^3D numerical simulation analysis,it is concluded that the value of the roadway floor movement is almost the same as that of the field monitoring,and the distribution of the roadway plastic area shows that the floor is broken to a large extent.Based on this,it is proposed that under the existing support system,the floor support body of"invert arch+grouting+anchor bolt"should be added to reinforce the roadway floor.
