  • Control system for overburden discharge
    Patent number: 6336684
    Abstract: An overburden removal system is provided which includes a bucketwheel (3) which cuts overburden from a wall (5) of the mine and discharges the overburden via a discharge boom (7) onto a hopper car (11) which travels on rails (9). The hopper car (11) delivers the overburden onto a conveyor belt (13). The system is characterized by a sensor (17) mounted on the hopper car (11) to detect the lateral position of the conveyor belt (13) relative to the hopper car (11) and a control device responsive to the extent of lateral drift for controlling the position of delivery of overburden into the hopper car.
