Analysis of footwall transportation roadway in middle section mining of metal mine
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.
