Forecasting of the blasting vibration is always the premise and basis of the controlling of the blasting vibration damage, and is an important subject of it. Based on the numerical simulation method of finite element, the calculation method of particle vibration velocity, an important index reflecting the blasting vibration intensity, is discussed; and an comparison analysis of the calculation results between two different kinds of charge structures decked with air and water is made. Numerical simulation results indicate that the calculation results are correspondent with the actual results if the distance from the blasting center is not far; it has certain significance to the design and construction of blasting.
