Abstract

Abstract

Blasting is an indispensable construction method to human beings. However, in the meanwhile, the rock vibration caused by blasting is one of blasting hazards. Due to the complicated geology, the peak particle velocity is a random variable approximately. It does not have a general function relationship with the maximum dose Q and the distance R from blasting center. Therefore, the vibration can only be described by the theory of probability. In order to control the vibration intensity and get high reliability, it is necessary to calculate the probability that the peak particle velocity is less than the safety vibration velocity of the target facility. Based on the probability, the distribution of peak particle velocity is approximately regarded as the normal distribution. Then safety analysis of target facilities and calculation of safe explosives are carried out. Finally, through the application of the case, it is reasonable to calculate the dose by probability formula.
- blasting,
- vibration,
- peak particle velocity,
- normal distribution,
- safety dose
