摘要
Abstract
The vibration produced in the blasting process will affect the stability of the mine slope.It is very necessary to research the blasting vibration regularity and its influence on slope stability during mine blasting.The relation data between the particle vibration velocity and the distance from explosive source in the process of mine blasting vibration are collected by the monitoring instruments,and the Sadowski's empirical formula suitable for the lithology of this area is modified by linear regression analysis,and the stability of mine slope is analyzed by numerical simulation software,and set the particle vibration velocity,displacement and maximum shear stress of the process points and monitoring points.The process point data can be mutually verified with the conclusions of blasting vibration attenuation law and damage mechanism of blasting vibration.The effectiveness and feasibility of this method are verified by a mine in Shiyan,Hubei province.The research shows that the fitting precision of the modified Sadolski empirical formula obtained by this method is high.This study provides a quick and simple analysis method for the hazard effect of blasting vibration on the mine slope.关键词
