Abstract
A continuous material extraction system for a mine. The mine includes a roadway entry and a draw-bell entry intersecting the roadway entry and affording access to a draw-bell. The system generally includes a conveyor extending along the roadway entry, roadway rails extending along the roadway entry, and a material collector moveable along the roadway rails. The material collector is operable to crush material and deposit crushed material onto the conveyor. The system also includes a loading machine that is moveable along the rails and from the roadway entry into the draw-bell entry for removing material from the draw-bell and transferring material removed from the draw bell to the material collector. A bridge conveyor extends between the loading machine and the material collector.
