ABSTRACT:
A hauling system for underground operations for use in an excavation between a longwall having a mining face and a drift comprises a longwall conveyor which is adapted to be positioned along the longwall and a drift conveyor adapted to be positioned along the drift. A cycloid is positioned between the drift and the longwall conveyors and provides a connection transfer therebetween. A plurality of plane guiding profiles are disposed along the long wall and they provide means for the passage of chains of a chain drive which includes a drive motor and transmission and sprocket located on the side of the drift conveyor. A winning machine, such as a coal plane, is mounted for guiding movement over the profiles and, in order to facilitate its movement up to the location of the juncture of the longwall with the drift, there is provided a deflection device in the form of deflection sprockets for the upper and lower reaches of the endless chain conveyor which is adjustably mounted on a flange plate which is carried on the periphery of the cycloid conveyor between the drift and the longwall.
