ABSTRACT:
An extensible conveyor for following a continuous tunneling or mining machine. The conveyor frame is made up of identical modules which can be added end to end at the end of the frame, the modules including return reach rollers. A separate carriage frame is independently supported on a mobile support which advances with the advance of the mining machine. The carriage frame advances over the conveying belt frame and includes a conveying belt pulley over which the conveying belt extends. The carriage frame spaces the conveying reach of the belt from the return reach thereof as the carriage is being advanced in order to allow conveying reach rollers to be placed onto the frame as the carriage frame advances. An impact plate is provided at the discharge end of a transfer conveyor, wherein the impact plate extends below the conveying reach of the belt of a first conveyor.
