Study on Critical Vibration Velocity of Underground Chamber with Different Surrounding Rock Mass Under Acting of Blasting Vibration
The wave function expansion method is used to analyze the interaction of blasting seismic wave and the adjacent underground chambers, the stress expression and displacement expression of circular underground chambers under the blasting vibration are deduced, the stress and displacement distribution of surrounding rocks mass are presented under the condition of different surrounding rock mass. In terms of the stress and displacement distribution and the tension strength of the surrounding rock mass, the critical failure vibration velocity of surrounding rocks mass is obtained in different condition.
