Primary Crushing Station

The primary crusher is mainly divided into gyratory crusher, jaw crusher, hammer crusher, etc. In addition to its own buildings and equipment, the primary crushing station also needs supporting facilities, such as upper ore bin, lower ore bin, conveyor gallery, oversize component gallery air raise, dedusting chamber, measurement chamber, etc.

Underground Mine Hoisting Sketches

In this case, ore is tipped into a hopper and loaded into a dump truck for transit to the crusher, where it will be reduced to -150 mm for subsequent conveyor transport. It is unlikely the crusher will be built into the headframe. For smaller mines the primary crusher may well be a mobile, quarry type and may even be leased rather than purchased.

What is Underground Mining?

The main method of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated from the surface downward to a depth somewhat below the deepest planned mining limit. At frequent intervals along the shaft, horizontal openings called drifts are driven towards the ore body.

First-of-its-kind ore handling solution puts safety first

Transporting ore underground presents significant challenges, depending on the excavation method used. In block caving, a large section of rock is undercut. The ore then collapses – or "caves" – gradually under its own weight. The resulting rubble funnels through a series of vertical ore passes at various levels in the mine.

Mining Methods VS Underground Crusher Location

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 body with workings far from the shaft.
