Comparison of Productivity When Running Filled, Near-Empty, or Flow-Through Orepass Using Discrete Event Simulation

Ore passes are often the main part of sublevel caving transportation systems, and they use gravity to move material lower levels in mine. During operations, ore pass structures exposed risk stoppage failure, leading a long-term reduction operational capacity affecting productivity. The failed can be restored or rehabilitated, but rehabilitation cost is normally high time restore usually long. To minimize disturbances pass, alternative strategies should considered. appropriate design operation an crucial. Therefore, this study compared running systems filled, near-empty, flow-through manner using discrete event simulation. aim was compare performance impact on reaching daily 90-day production targets 76.4 Ktonnes 6.9 Mtonnes, respectively. results showed that mode, filled manner, near-empty achieved 96%, 80%, 81% target, In mining operations where used transfer material, them mode ensure higher fewer hang-ups, as it lessens chance blocks arching over chute throat leads less blasting.
