Blasting Excavation Vibration Testing and Analysis of Underground Chamber
During the excavation of underground chamber, the wall-rocks stability will be destroyed by the blasting seismic wave. Through monitoring the blasting vibration of Xinji Coal Mine, this paper adopts least-squares procedure and mathematical statistics to study the rule of attenuation and the upper limit and the lower limit of value K, define the blasting vibration value in this underground chamber, and use the regression formula to direct the designing of blasting. The results indicate that the regression formula can direct blasting excavation conveniently and supplies reliable proof for the stability of the chamber under the blasting vibration.
