摘　　要：金川矿区岩石力学与巷道支护的研究已有几十年的历史,但是随着矿山开采深度的增大和大面积开采的采动影响,深部巷道围岩表现出明显的碎胀蠕变特性,巷道支护问题已成为矿区可持续发展的关键。通过对喷锚网支护概况的介绍、作用机理的分析,以及队以喷锚网支护为主的支护方式的评价,并对今后的发展提出建议,旨在解决金川矿区巷道稳定问题。Research on the rock mechanics and roadway support for Jinchuan mine area has a history of decades.But with the increase of mining depth and large mining impact,deep rock tunnel showed a clear crack - expansion creep,so roadway supporting has become the key to keep the sustainable development.By introducing the spray anchor net supporting and its mechanism analysis,as well as evaluation on support method by the spray bolting,the future development proposals aiming at keeping roadway stability of Jinchuan mine are proposed.
