Abstract

The invention provides a blasting method and system for reducing blasting vibration, relates to the field of blasting, and selects blasting design parameters through the maximum dominant frequency and peak particle velocity of vibration signals. Firstly, a vibration signal of tunnel blasting is obtained; denoising the vibration signal based on discrete wavelet transform to obtain a low-frequency vibration signal; extracting the maximum dominant frequency of the low-frequency vibration signal; calculating a peak particle velocity corresponding to the maximum dominant frequency; judging whether the peak particle velocity is smaller than a threshold range or not; if yes, the ratio of the blasting explosive quantity to the blasting delay is increased, blasting continues, and then the obtained vibration signal of tunnel blasting is returned; and otherwise, blasting is stopped. The method is not influenced by areas or noise related problems in the existing method, and the influence generated by vibration caused by blasting can be reduced to the maximum extent.

Description

technical field [0001] This paper relates to the field of blasting, in particular to a blasting method, system, medium and equipment for reducing blasting vibration. Background technique [0002] Tunnels are the key and key projects in the construction of highways and railways. With the development of railway construction and the advancement of science and technology, tunnel excavation methods have been developed rapidly. Due to its strong adaptability to geological conditions and low excavation cost, the drill-and-blast method is especially suitable for the construction of hard rock tunnels, broken rock tunnels and a large number of short tunnels. Therefore, the drill-and-blast method is still the commonly used tunnel excavation method at home and abroad. [0003] Tunnel blasting will generate huge energy, which is closely related to blasting charge and blasting delay. If the blasting charge is too large or the blasting delay is reduced, the energy caused by blasting will...
