Mining Methods VS Underground Crusher Location

11-05-2017  Ore is typically passed from sublevels to haulage levels where it is trammed by rail to either the shaft, or to a large crusher from which it may be belted to the shaft. This latter arrangement would be more likely in a mine having more than one underground crusher, or a laterally extensive ore

Underground hard-rock mining - Wikipedia

In mines which use rubber tired equipment for coarse ore removal, the ore (or "muck") is removed from the stope (referred to as "mucked out" or "bogged") using center articulated vehicles (referred to as boggers or LHD (Load, Haul, Dump machine)). These pieces of equipment may operate using diesel engines or electric motors, and resemble a low-profile front end loader. LHD operated through electricity utilize trailing cables which are flexible and can be extended or retracted on a reel.

Crusher - an overview ScienceDirect Topics

Medium-sized jaw crusher in operation in underground mine for crushing run-of-mine (ROM) ore before transferring to the surface. The gyratory crusher consists of a long, conical, hard steel crushing element suspended from the top. It rotates and sweeps out in a conical path within the round, hard, fixed crushing chamber (Fig. 13.11).

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
