| Abstract: |
| Based on the kinematics theory to derive the collision position and collision energy of the ore when it moves in the ore pass, taking the collision frequency and cumulative damage energy of collision as the factors to represent the deformation and destruction state of ore pass wall. The collision damage model of moving particle is set by Python. The collision frequency is positively related to the cumulative damage energy of collision, both of which can represent the deformation and destruction state of ore pass wall. The calculated distribution of damage status of ore pass wall is basically consistent with the actual collapse pattern of ore pass, which validates the rationality of the derivation process and the applicability of the model. |
