Broken Hill Ore Chute Design - AusIMM

In the matter of chute construction for the handling of the ore broken in the stopes, each mine belonging to the above companies has adopted a style particularly its own, though it may be said that one or two of the types approximate very closely to each other, slight minor differences only being noticed in the design.

Designing reliable transfer chutes with bulk material simulation: a

When the final design 3D model is adequate, we will run a DEM simulation of the chute which we then use to optimize the final chute design. Here is a real-case example of a project we worked on for a client. A vertical Ore Pass section of approximately 105 meters is filled with Kimberlite. The material can drop 105 meters and impact onto a ...

Ore Pass - Mining Fundamentals

May 24, 2014  The intervals between ore passes should not exceed 500ft, or 150m. Ore pass inclination should be maintained between 45° and 90°, while ore pass length should be in the range of 10m to 300m. References.

BULKtalk: Best practice in chute design – Part one – Australian Bulk Handling Review

Apr 02, 2019  Chute systems are easier to design if the geometry of the plant provides in-line or right-angled transfers. Other alignments are feasible but may require more space or height for an effective design. Chute systems are always a compromise if there is insufficient space and height in the layout for all required functions at the detail design stage.
