Variant Mining creates world's largest ore chute Sudbury
2019-8-7 An ore chute is a device that allows chunks of rock (muck) to be transported by force of gravity from one level of the mine to another level. The chute is used to control the flow of muck, or waste rock, so that haulage equipment such as scooptrams, ore trucks or even underground rail cars can be loaded quickly and safely.

Ore is extracted from LKAB's underground mines by means of sub-level caving. The method is based on creating cavities in the ore body through drilling and blasting. When the ore is removed, waste rock collapses down and automatically fills the cavity. Sub-level caving is based on creating cavities in the ore body and allowing the ore to fall
