摘　　要：巷道稳定性是保证矿山安全生产的基础。基于此以某金属矿山为研究对象,首先分析了该矿山的开采现状;其次,对运输巷道应力集中机理进行了分析研究,并进行了工程验证;最后,对巷道的变化结果及开挖后岩体位移场对巷道影响进行了分析。希望可以为后续矿山巷道的稳定下分析提供技术支持。Roadway stability is the basis to ensure the safety of mine production.Based on this,a metal mine is taken as the research object.Firstly,the mining status of the mine is analyzed.Secondly,the stress concentration mechanism of transportation roadway is analyzed and studied,and the engineering verification is carried out.Finally,the change results of the roadway and the influence of the displacement field of the rock mass on the roadway after excavation are analyzed.It is hoped that it can provide technical support for the stable analysis of subsequent mine roadways.
