Abstract
Certain exemplary embodiments can provide a system, which can comprise a bucket excavation controller. The bucket excavation controller can be adapted to control one or more digging functions of a mining excavator. For example, the bucket excavation controller can be adapted to automatically control a crowd motion of the mining excavator.
Claims18
An excavation system, comprising:
- a positionable haulage vehicle for hauling earthen material;
- an excavator having a positionable bucket coupled to a hoist motor for excavating earthen material, the excavator having coupled thereto:
- a bucket excavation controller adapted to adjust a digging position of a bucket of the mining excavator in an earthen material bank;
- a material weight processor adapted to determine a weight of earthen material in the bucket;
- and
- a mining haulage vehicle position processor coupled to the excavator, adapted to determine automatically a desired location of a mining haulage vehicle relative to said mining excavator.

An excavation system, comprising:
- a positionable haulage vehicle for hauling earthen material;
- an excavator having a positionable bucket coupled to a hoist motor for excavating earthen material;
- a bucket excavation controller, coupled to the excavator, adapted to:
- responsive to an automatically detected stall) condition at the hoist motor, automatically) control a crowd motor of the mining excavator,
- the crowd motor adapted to adjust a position of the bucket in an earthen material bank;
- and
- responsive to an automatic determination that a speed of the hoist motor exceeds a predetermined threshold, automatically control the crowd motor to adjust the bucket position in the earthen material bank;
- a material weight processor, coupled to the bucket excavation controller, adapted to determine a weight of earthen material in the bucket;
- a mining haulage vehicle position processor coupled to the excavator, adapted to determine automatically a desired location of a mining haulage vehicle relative to the mining excavator;
- and
- a mining haulage vehicle load processor adapted to, based upon a received scan of a bed of the mining haulage vehicle, determine automatically a desired location of the bucket relative to the bed of the mining haulage vehicle.

- a material weight processor, coupled to the bucket excavation controller, adapted to determine a weight of earthen material in the bucket and thereby enabling the bucket excavation controller to adjust bucket position on the basis of the determined weight;
- a mining haulage vehicle position processor coupled to the excavator and the haulage vehicle, adapted to determine automatically a desired location of a mining haulage vehicle relative to the mining excavator and thereby enabling the excavator and hauler to adjust their relative positions to the desired location;
- and
- a mining haulage vehicle load processor, coupled to the bucket excavation controller, the haulage vehicle load processor adapted to, based upon a received scan of a bed of the mining haulage vehicle, determine automatically a desired location of the bucket relative to the bed of the mining haulage vehicle, and thereby causing the bucket excavation controller to adjust bucket position to the desired location.
