ARMORED FACE CONVEYOR

摘要

An armored face conveyor includes a plurality of line pans positioned adjacent to one another, a plurality of flight bars, and a connecting member. Each line pan includes a race having an outer race face and an inner race face. The plurality of flight bars extend laterally across the line pans and are received by the race. Each flight bar includes an end having an upper guide surface and a lower guide surface. The connecting member extends through the plurality of flight-bars and couples the flight-bars to one another. Lateral movement of any one of the flight-bars that causes the upper guide surface to contact the outer race face substantially simultaneously causes the lower guide surface to contact the inner race face.

1. A material extraction system for an underground mine, the system comprising:
a material-cutting machine; and a face conveyor for transporting material cut by the material-cutting machine, the face conveyor including: a plurality of line pans positioned adjacent to one another, each line pan including a race defining an extended portion having a substantially vertical outer race face and a substantially vertical inner race face positioned below the extended portion, the extended portion being substantially perpendicular to the vertical inner race face, a plurality of flight-bars extending laterally across the line pans and received by the race, each flight bar including an end having an upper guide surface facing the outer race face and a lower guide surface facing the inner race face, and a connecting member extending through the plurality of flight-bars and coupling the flight-bars to one another, wherein lateral movement of any one of the flight-bars causing the upper guide surface to contact the outer race face substantially simultaneously causes the lower guide surface to contact the inner race face.
