Numerical simulation on the influence of boreholes arrangement and delay time on coal crushing effects

According to the effect of different charging and boreholes arrangements and delay time on coal crushing effect in coal blasting,this paper used ANSYS-LS/DYNA to carry out numerical simulation and analyzed the calculation results.The results show that the explosion stress wave has an supper position...
