论文基于深部高应力软岩硐室围岩稳定性的几种影响因素,提出软岩加固理念。通过高预应力高位恒阻让压技术、分步注浆技术在该矿硐室的组合应用,解决软岩硐室加固问题。实测结果表明:硐室围岩两帮、顶板、底板变形量分别减少了82.5%、25%和88.9%。 Based on several factors that affect the stability of surrounding rock in deep, high stress soft rock chambers, the paper proposes the concept of soft rock reinforcement. Through the high prestressed high constant pressure to allow pressure technology, step grouting technology in the mine chamber combination of applications to solve the problem of soft rock chamber reinforcement. The measured results show that the deformations of the two gangs, roof and floor in the surrounding rock of the chamber have been reduced by 82.5%, 25% and 88.9% respectively.
