Abstract

Through analyzing the factors of blasting effects on quality of surrounding rock mass, the modifying coefficient expression of blasting effect on basic quality index of rock mass is obtained on the basis of the formula used to calculate BQ index of basic quality of rock mass. Based on the experiments in laboratory and in site, the regularity and degree of blasting effect on basic quality of rock mass is analyzed.
