【摘要】 长期动水条件作用下巷道会发生局部渗水、漏水以及顶、底板发生破坏,严重影响巷道服务年限,并造成重大安全隐患,针对这种环境下巷道破坏的特点与机理,通过大量工程实例对比,提出了注浆结合锚杆支护对巷道进行综合治理,增强巷道整体稳定性与防渗性,从而延长巷道服务年限,对相关工程的维护具有指导意义。更多还原

【Abstract】 Under the long-term hydrodynamic condition,local permeation,leakage,and roof-floor destruction occurs,which seriously shortens the service life of roadways and causes serious hidden danger.By comparison with engineering cases,the paper proposes the comprehensive treatment with grouting and anchoring for the roadway the destruction features and mechanism mentioned above.The whole stability and permeation-preventing ability are strengthened,and the service life of roadways is prolonged,which has directive significance for the maintenance in the similar situations.更多还原
