Fast and Efficient Opening Construction Method for Comprehensive Excavation of Rock Roadway
As the mining intensity of the mine gradually increases,it is imperative to achieve mechanical and rapid excavation in excavation engineering to ensure dynamic balance of the three quantities.In response to the problem of traditional tunnel opening construction using blasting,which has complex construction technology,multiple procedures,low construction efficiency,and cannot meet the needs of safe and efficient production in mines,two construction methods are proposed based on the belt descending from the 18th mining area of Chensilou Coal Mine,Yongmei Group.They are comprehensive excavation machine rock breaking +bridge type transfer machine transfer +belt machine discharge,and comprehensive excavation machine rock breaking+rake loading machine discharge+belt machine discharge.A systematic analysis of the key factors in the construction of tunnel openings was conducted.Through the rapid and efficient construction method of rock tunnel comprehensive excavation,multiple equipment were coordinated and linked,and mining areas and horizontal gangue bins were set up to solve the problem of gangue transfer and transportation,achieving rapid and efficient excavation of engineering comprehensive excavation.
