Abstract
A method for reducing blasting vibration of tunneling includes the steps of: dividing the cutting holes into several groups according to different cutting methods; conducting layout and test blasting on one group of cutting holes; testing blasting parameters for the layout and test blasting; calculating an interval t; conducting layout and test blasting on at least two groups of cutting holes again; testing blasting parameters for the layout and test blasting of each group for the second time; taking the minimum interval t of each group as the interval for formal blasting of the remaining groups of cutting holes. The use of the characteristics of the wave in the invention can superpose the peaks and troughs of the vibration wave, and further cancel out mutually; reduce the peaks of the blasting vibration and fill the troughs of the blasting vibration.
