摘要
通过采用数值模拟方法,模拟分析了潞安屯留煤矿副井井筒及井底车场附近巷道和硐室在开挖前后围岩应力场的变化规律,为井筒及硐室加固提供了理论依据,为今后类似条件下井底车场设计及施工提供参考。
Stress distribution rules of surrounding rock of shaft station and neighboring caverns before and after mining in Tunliu Colliery of Lu＇an Group were analyzed by numerical simulation, which provided theoretic foundation for supporting shaft and caverns and provided reference for shaft station design and construction with similar conditions.
