摘要:
摘要:在厚泥岩顶板条件下,大跨距高帮硐室存在围岩稳定性差,支护难度大、换装设施的可靠性低等难题。在分析围岩地质条件的基础上,根据相关设计规范,确定合理的支护参数,设计施工方法及工艺。现场施工应用结果表明,换装硐室围岩收敛较小,支护效果良好。

Abstract:
Abstract: Under thick mudstone roof circumstance,large span and high rib heading stability of enclosing rock was more inferior,and support was more difficult. Based on analyzing geological conditions of enclosing rock, in accordance with relevant design criterion,reasonable support parameter was determined,then construction methods and technology was designed. The in-situ experiment result showed that enclosing rock of reloading heading appeared less deformation, the support was effective.
