Factors Affecting Rapid Excavation of Coal Roadways and Optimization of Excavation Technology
In order to further explore how to improve the quality of rapid excavation work in coal roadways,2104 working face of A Mine in Shanxi Province was taken as the research object.In response to the problem of high deformation of the tunnel during the rapid excavation process in coal roadways,the numerical simulation analysis method was applied to analyze the reasons for this problem,and optimization strategies for excavation process parameters were formulated.On this basis,targeted optimization design was carried out on the coal rock cutting and support schemes and their related parameters in the excavation process through existing experience and relevant theories.The results indicate that the optimized excavation process has achieved good results in reducing coal roadway deformation and has certain application value.
