Analysis and numerical simulation on parameter optimization of low hardness coal pre-splitting blasting
In view of the characteristics of low coal hardness and permeability of a certain area, in order to confirm suitable cartridge radius and non-coupling charging coefficient, and improve coal blasting efficiency in the area, software of ANSYS/LS_DYNA was used for simulation analysis of blast cracking,...
