Research on Optimization of Technological Parameters for Comprehensive Excavation of Rock Strata Tunnels
A large coal mining company did not improve its excavation efficiency and mining progress after adopting comprehensive excavation equipment.The existing problems were analyzed from the current construction plan,drilling site construction technology,support plan,and gangue transportation plan,and effective optimization processes were proposed.According to the on-site improvement situation,it can be seen that after adopting the optimization plan,the excavation speed has been increased from 160 m/month to 240 m/month,a relative increase of 50%,and the cost of support equipment has been reduced by more than 1.4 million yuan,greatly improving the mining situation and economic benefits of the mining area.
