The Method of Optimizing Blasting Parameters for Driving Tunnel Based on the Outcome Analyses

摘要

To get optimum blasting parameter bringing out the best blasting outcome is very helpful to increase the speed and efficiency in tunnel-building. For this reason, the effect of blasting parameters on blasting outcome is analyzed based on that the rocks are complex and changeful through which the tunnel is driven and that there is a gap between blasting theory and blasting practice. The method helpful to get the optimum blasting parameters is present in which the blasting outcome is measured, recorded and analyzed, and the blasting parameters are adjusted aiming at the specific tunnel according to the blasting theory and the blasting technician's experience. The presented method is important and significant for improving the tunnel-building technique by blasting, realizing the high speed and efficiency of tunnel-building by blasting.
