摘要
深部回采中的冲击地压问题长期以来一直是威胁矿井生产安全的主要因素,实现对其的有效防治意义重大。结合具体工程实际,在分析巷道变形破坏特性与破坏机理的基础上,提出"全断面注浆+注浆锚索"联合支护方案,并对其支护效果做出监测分析。结果表明联合支护方案实现了对巷道围岩变形破坏的有效控制,实现了对冲击地压的防治,为矿井安全提供了有力保障。
The problem of rock burst in deep mining has long been the main factor threatening the safety of mine production, and it is of great significance to achieve the effective prevention and control. Based on the analysis of failure characteristics and failure mechanism of roadway deformation, this paper put forward the combined support scheme of "full section grouting + grouting anchor rope" and made monitoring analysis of its support effect. The results show that the combined support scheme can effectively control the deformation and failure of roadway surrounding rock, prevent and control rock burst and provide a strong guarantee for mine safety.
