摘　　要：为确保矿井的安全生产建设,需对永丰煤业井田巷道穿过村庄保护煤柱区域的围岩稳定性及变形情况进行分析研究。通过煤柱及巷道稳定性计算,评价矿井巷道为安全稳定;FLAC3D数值模拟结果表明,永丰煤业巷道现有支护方式可有效控制围岩变形,巷道支护后掘进通过村庄保护煤柱时,仅会引起其上覆顶板0~6m范围、两帮0~3m范围的围岩发生变形,不会对上部覆岩及地面造成影响,对村庄保护煤柱区域地表沉陷变形无影响。In order to ensure the safety production and construction of the mine,it is necessary to analyze and study the stability and deformation of the surrounding rock of the Yongfeng Coal Industry mine roadway passing through the village protection coal pillar area.The safety and stability of mine tunnels is evaluated by calculating the stability of coal pillars and tunnels.The numerical simulation results of FLAC3D show that the existing support methods of Yongfeng Coal Industry roadway can effectively control the deformation of surrounding rock.When the roadway is excavated through the village protection coal pillar after support,it will only cause deformation of the surrounding rock within the 0-6 m range of the overlying roof and the 0-3m range of the two sides,and will not affect the upper overlying rock and ground.It has no effect on the surface subsidence and deformation of the village protection coal pillar area.
