Abstract:
In order to solve the problem of selecting the parameters of medium and deep hole blasting in Pingchuan Iron Mine, the theoretical calculation combined with software numerical simulation is used in this study. First of all, the theoretical formula in accordance with the explosive unit consumption and the amount of ore per metre as the optimal conditions to calculate the conditions of the mine in line with the medium and deep hole blasting parameters, and then through the ANSYS/LS-DYNAD numerical simulation calculations on the calculation of the various sets of parameters, according to the simulation of the analysis of the effect of the blasting, to obtain the optimal deep hole blasting parameters suitable for the mine under different conditions.
