<p>A material extraction system for an underground mine includes an elevated haulage conveyor extending between first and second ends of a roadway entry. The haulage conveyor is cantilevered from a mine wall and conveys material toward either end of the roadway entry. The system also includes a crusher including a drive operable to move the crusher along the roadway entry. The system further includes a bridge conveyor including a first end adjacent the crusher and receiving material from the crusher, and a second end adjacent the elevated haulage conveyor and positioned for depositing material onto the elevated haulage conveyor. The bridge conveyor is moveable with the crusher along the roadway entry. The system also includes a loader moveable along the roadway entry and into and out of material collection entries to collect material therefrom and transport the material to the crusher.</p> |
