Ore sorting and pre-concentration - Resourceful Paths
Modern ore sorting relies on sensors to detect properties of particles, and based on readings, respond with a control action. There are two methods: Bulk sorting, where loads of material (e.g. in a shovel, in a truck or a length of material on a conveyor) are directed to a destination based on measured properties

What Is An Ore Pass In Mining? - Flyability
Ore passes take advantage of gravity to move materials from one level of a mine to another. There are two methods for developing an ore pass: the drill and blast method and the mechanical method. The drill and blast method requires miners to drill a hole in the location of the ore pass to then place explosives, blasting a hole for the ore pass.

This is a very labor-intensive method. As an overhand stoping method, holes are drilled, loaded, and shot. A portion of the broken ore is drawn off to create sufficient space to allow the drilling and blasting operations in the stope. Once the newly drilled holes are drilled and loaded, the miners and equipment will be withdrawn.

Underground Mining Methods - Mining Matters
Sublevel stoping is a mining method in which ore is blasted from different levels of elevation but is removed from one level at the bottom of the mine. Before mining begins, an ore pass is usually drilled from a lower to a higher elevation. Jumbos selectively drill holes into the roof of the drift and fill them with explosives.
