Abstract

Abstract: In order to determine the maximum chassis resistance line in the step blasting of the Barun mine, ANSYS/DYNA numerical simulation was used to simulate four sets of models with different chassis resistance lines of 1200cm, 1150cm, 1100cm and 1050cm, and the bottom line of the slope was analyzed according to whether the rock was broken. Whether the stress value of the continuous unit reaches the yield strength of the rock, the maximum chassis resistance line value is 1150 cm, and it has been verified by field industrial tests. The actual working conditions show that the simulation results show that the chassis resistance line is 1150cm, and the bottom plate is flat after blasting. There is no obvious foundation, which meets the mining requirements of the mining equipment, and it is feasible in the Barrun mine.
