Measurement and Analysis on Deep Borehole Blasting Vibration in Base Rock Section of Mine Shaft
Abstract：Inorder to reduce the vibration function of the blasting construction to the surrounding rock of the mine shaft,according to the mine shaft cross section,rock property,drilling and blasting equipment and material and other factors,an optimization design was conducted on the blasting parameters.Based on the seismic transmission features and the blasting vibration measuring principle,a site monitoring and measuring method of the deep borehole blasting vibration in the mine shaft was provided and the seismic transmission law of the blasting in the base rock was studied.With the regression analysis on the blasting vibration signals,an experiences formula suitable to the blasting vibration attenuation law of the project was obtained and could provide the basis to predict the blasting seismic strength and to conduct the vibration control measures.
