Abstract: In the mining process,the majority of underground metal mines adopted explosive blasting.Seismic waves produced by blasting spread to the ground surface,which have an impact on the safety of the buildings and facilities on the ground.For this problem,the on-site monitoring of the impact of the stope blasting vibration on the ground environment is carried out,thus obtaining blasting vibration monitoring data.Peak particle velocity evaluation method is selected to analyze the impact of blasting vibration.By linear regression of the data using the least squares method,Sadov's Vibration Formula about underground stope is gained.Through the formula,blasting vibration velocity with different doses and different distances are predicted,and three parameters of vibration velocity and frequency,duration were compared with the corresponding data generated by train traffic vibration.Then,the dose control standards for stope blasting vibration are proposed.

Key words: Blasting vibration, Underground mine, Safety impact, Monitor
