深部软岩大断面硐室围岩稳定性控制技术研究

Research on Stability Control Technology for Surrounding Rock of Large Cross Section Caves in Deep Soft Rock

深部煤炭资源是现代煤矿资源开采的一项重点研究对象。从开采角度入手开展相应分析作业,岩石特性与应力情况十分复杂;与此同时,为实现智能化和节约化生产,很多超大断面硐室群都要在井下布置,且分布比较密集,在复杂的环境影响下,极易产生围岩变形失稳问题,威胁到的硐室安全。现针对深部软岩大断面硐室围岩稳定性控制相关内容,展开具体的论述,提出稳定性控制的策略。

Deep coal resources are a key research object in modern coal mining.Starting from the perspective of mining,corresponding analysis operations are carried out,and the rock characteristics and stress situation are very complex.At the same time,in order to achieve intelligent and economical production,many super large cross-section chambers need to be arranged underground and are densely distributed.Under the influence of complex environments,it is easy to cause deformation and instability of surrounding rocks,which poses a threat to the safety of the chambers.This article provides a specific discussion on the stability control of the surrounding rock of large cross-section tunnels in deep soft rock,and proposes strategies for stability control.
