Numerical Simulation on Selection of Optimal Delay Time for Precise Delay Blasting
In the traditional presplitting blasting, the presplit holes are generally uniformly initiated, which causes local damage to the retained rock mass while forming the damping ditch. In order to determine the optimal delay time of the precise delay initiation hole by hole, the finite element software...
