Influence of Blasting Vibration on Roadway Loose Range

Abstract:

Roadway loose scope nearby the excavation section was tested by sound wave loosing zone testing instrument. According to the analysis: the shorter distance to the excavation section, the more influence by blasting vibration; the influence is decreased along with the distance increased, and finally to stabilize. Meanwhile, numerical simulation on effective stress of rock nearby blasting section was did with ANSYS/LS-DYNA, got the same conclusion as testing. The research result can provided a basis for reasonable selection of blasting parameters, reduce blasting vibration effect.
