AN IMPROVEMENT TO THE EQUATION FOR THE ATTENUATION OF THE PEAK PARTICLE VELOCITY

LU Wen bo 1,Hustrulid W 2 (1 Wuhan University,Wuhan 430072,China; 2 University of Utah,UT84112,U S A.)  
On the basis of the analysis of the theory of the cylindrically elastic wave,the theory of the seed wave induced by a long cylindrical charge and the Heelan Solution for stress wave field induced by a short cylindrical charge,a new equation for the attenuation of the Peak Particle Velocity (PPV) during rock blasting is derived The equation is verified by both experiment data and the result of simulation with FLAC Compared with the traditional equation,the proposed equation is on a more reasonably theoretical basis,and such factors as the types of the explosive used,the characteristics for explosive and rock,the diameter of blasting hole and coupling or decoupling condition of the charge,etc,could all be included in the new equation
