A base rock section of the new west ventilation shaft in Panji No.3 Mine was excavated with a drilling and blasting method.In order to analyze and study the blasting vibration affected to the mine shaft liner and the freezing pipe,in the blasting construction,three set blasting vibration measuring and test instruments were set around the mine shaft head.Each instrument individually would set three vibration meters in vertical,horizontal radial and horizontal tangential individually and would be applied to the measurement and analysis on the blasting vibration.The results showed that a max vibration speed from a measuring point was in vertical direction and was 2.359cm/s.Within an allowed scope,no failure influence would be occurred to the freezing pipe and the mine shaft liner.
