AN APPLICATION STUDY OF NUMERICAL SIMULATION IN PRESPLITTING BLASTING

摘要

Numerical calculations of the blasting process under the uncoupling loading in presplitting blasting are made in this paper. The checking and verification of numerical simulation results are conducted with the help of experimental curves, indicated that the results obtained conform to the theoretical analysis. A new means for deep understanding of rock blasting damage process and presplitting blasting mechanism is provided, and an effective method for theoretical study of blasting and blasting engineering design presented, which is of great significance to the actual presplitting blasting engineering.
