Numerical Analysis of Effect of Blasting Vibration on Adjacent Roadway in 858 Mines

Abstract:

In order to avoid the effect of driving blasting on the adjacent roadway in 858 mines, numerical analysis of seismic intention was carried out. Based on monitoring data, the parameters suitable for local were obtained by Sadov's formula, by which the relationship between the maximum single-stage charge and the width of protect rock pillar were offered. According to design requirements, and considering the effect of driving blasting on the adjacent roadway, the maximum single-stage charge of driving blasting is 43.99kg.
