Abstract
A material extraction system is provided for an underground 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 loader movable from the roadway entry into the draw-bell entry for removing material from the draw-bell, a sizer coupled to the loader for sizing the removed material, a material collector operable to collect the sized material, and a shuttle car operable to receive the collected material from the material collector. The material collector has a loading end and a discharge end, and material transport device extending therebetween. The shuttle car is movable along the roadway entry for transferring the collected material so as to facilitate a substantially continuous extraction of the material.
