摘 要:西翼胶带大巷受高应力地质条件等综合因素影响,巷道整体出现持续性变形现象,通过分析该地质条件下巷道围岩特点及变形破坏机理,从改善围岩结构整体性、强化支护体系作用入手,确定采用扩修后对巷道进行高强高预紧力锚网索+新型无机材料注浆加固的方法。现场矿压观测验证,该方法能够减少巷道变形量及返修量,达到较好的支护效果。The belt roadway in the west wing is affected by comprehensive factors such as high stress geological conditions, and the whole roadway appears the phenomenon of continuous deformation. Through the analysis of the characteristics of roadway surrounding rock and its deformation and failure mechanism under this geological condition, starting with improving the integrity of surrounding rock structure and strengthening the function of support system, the method of high strength and high preload anchor net cable + new inorganic material grouting reinforcement for roadway after expansion and repair is determined. The field mine pressure observation shows that this method can reduce the roadway deformation and repair amount, and achieve a better support effect.
