System for conveying bulk material and people in a mine

Abstract

A conveyor system has a track defining an endless path traversing a loading station and an unloading station and having a transport stretch therebetween, an annular succession of longitudinally spaced trucks riding on the track, and an endless conveyor belt extending along the track and having a pair of longitudinally extending edges one of which is suspended from every other truck and the other of which is suspended from the remaining trucks. A drive element extends along the track and engages the trucks to advance the belt in a longitudinal transport direction from the loading station through the transport stretch to the unloading station and then back to the loading station. At least one carrier is connected to the lower end of at least one hanger having an upper end releasably attachable to the belt so as to suspend the carrier from the belt in the transport stretch. The carrier can be a flat rigid pallet having corners each connected to the lower end of a respective such hanger. It can also be an upwardly open material-carrying vessel similarly having corners each connected to the lower end of a respective such hanger or a simple skilift-type chair suspended from a rigid hanger, a system which makes it very convenient for individuals to move along the often very long transport stretch in a mine.
