深部软岩巷道全锚索注浆加固治理技术

摘要

该文分析了影响巷道支护效果的主要因素，针对影响因素采取“锚、注、喷”为主要支护方式，对深部软岩巷道扩修采取了“扩修一次支护”、“顶板注浆加固”、“全锚索二次加强支护”、“顶帮底全断面二次注浆加固”、“底板水治理”的治理措施，获得了良好的效果。%This paper analyzed the main factors influencing the effect of roadway support, aiming at the influence factor, took the "anchor, spray, grouting" as the main supporting way, of deep soft rock roadway expansion and repair has taken‘extended repair', first support, roof grouting reinforcement, two times support using anchor cable ,and the roof, floor and two ribs of whole section grouting reinforcement, "floor water governance" measures, obtained a good results.
