| Abstract: | According to testing and analysis of mechanical properties of rock,double bench cutting was adopted with large-diameter hole,large-diameter cartridge,other holes with small diameter hole in order to improve blasting effect.By measuring the operations of the time,construction processes were optimized with rational allocation of drilling implements.Results indicate that this method increases excavation efficiency and implements rapid excavation. |
