The mining conveyor has drivers, which may be moved to- and fro, in a conveyor trough, in and against the direction of conveyance. The driver (11) have a steep front surface (13), and a shallow rising rear surface (14). Return flow restriction elements (17) are positioned between the driver. The restriction elements are stationary or may be movable in both directions opposite to the drivers. The elements have front and rear surfaces (18,19) similar to the drivers. Drivers and/or restriction elements may consist of triangular profiled sections. |
