ABSTRACT:
A pneumatic stowing apparatus for use in underground mine galleries for pneumatically transporting mine waste resulting from blasting operations, mainly comprises a housing in which an element forming at least one chamber is movable between a material receiving position in which such mine waste is filled through an inlet opening in the housing into the chamber and a material-discharging position in which opposite open ends of the chamber are respectively aligned with openings in opposite end walls of the housing, through one of which compressed air is blown over a valve into the chamber so that the mine waste in the latter is transported to a point of use through a discharge conduit connected to the opening in the opposite end wall of the housing, a motor to move the chamber forming element between the positions thereof, and a member for opening and closing the valve in timed sequence with the movement of the chamber forming element.
