Study on propagation laws of blasting vibration in deep roadway

摘要

According to field condition, blasting vibration of medium deep-hole blasting in deep rock entry were tested for study the influence of entry by blasting vibration in coalmine, attenuation coefficient α of earthquake wave and equation coefficient k are acquire by regression and analysis on point vibration peak velocity and acceleration of tested results, then summarizes propagation laws of blasting vibration in deep rock roadway: radial component(included velocity and acceleration directions) of blasting vibration play a leading role in blasting seismic effect.
