深部邻近巷道相互扰动作用下支护方法研究

摘要

结合朱集矿的现场情况，分析了巷道次生应力对邻近巷道支护结构变形和稳定性的影响，探讨了深井地压下新开巷道的次生应力及其对邻近既有巷道围岩稳定性的影响，研究了深井高地应力下巷道次生应力在相邻巷道间的显现效应，提出了一套锚架组合支护方法，大幅度减少了该情况下的巷道变形，对于合理设计地下邻近巷道间的相互位置，具有重要意义。%The influence of induced stress on supporting structure deformation and stability were analyzed by combining actual condi -tion of Zhuji Colliery.Induced stress of new-excavate roadway in deep shaft and its influence on adjacent roadway were discussed .A set of combining supporting method including anchorage and support was set up which reduced largely roadway deformation .This had im-portant significance for rationally designing mutual alignment of adjacent roadways .
