软围岩交岔点锚网喷支护的应用及研究

Application and Research on Support of Bolt,Net and Spraying in Intersection of Soft Surround Rock

通过对锚网喷支护的力学分析,结合松散破碎围岩的破坏特征,设计并确定支护工艺参数,进行锚网喷联合支护对松散破碎围岩交岔点的试验研究,以探索西曲矿在软围岩条件下的支护改革。

Through analysing the mechanics condition of support of bolt, net and spraying, combines the destroyed characteristic of loose and brokes surround rock, designs and determines technique parameter of support, experiments and researches the support of bolt , net and spraying to intersection of loose and brokes surround rock, so as to explore reformation of support in Xiqu coal mine under condition of soft surround rock.
