Abstract:

In recent years, computer⁃controlled rock drilling rigs are introduced into tunnel engineering tocarry out blasting and excavation. In this paper, a blasting parameter optimization method based onMonte Carlo simulation is proposed, and the blasting construction design of Angsiduo Tunnel is applied toimprove the application efficiency of the computer⁃controlled vehicle. The method includes borehole dataanalysis, blasting scheme layout design, and Monte Carlo simulation to determine the optimal charge.The results show that the contour surface generated according to the drilling data can optimize thepositioning of the blast hole, the number of holes and the amount of charge, so as to improve theefficiency of blasting operation.
