Abstract: Disclosed herein are a method and system for controlling a drill rig by utilising a drill control module. A drill control module for controlling functionality of a drill rig comprises: a processor; a storage medium for storing a computer program having instructions that when executed on the processor perform the method steps of: drilling a hole by repeatedly: activating a hammer drilling mode for a predefined interval parameter, said activated hammer drilling mode causing a drill bit of said drill rig to impact a surface using a hammer drilling technique; and activating a pause interval for a predefined interval time, during which said drill bit reduces engagement with said surface.

Abstract: Disclosed herein are a control method and system. The system includes: a deactivation control; a control centre controller for storing an association between the deactivation control and a selected set of mine sites; a plurality of autonomous drill rigs, each drill rig having a drill shutdown module to disable a function of the respective drill rig upon receipt of a deactivation command; and a mine site controller associated with each mine site, each mine site controller being coupled to all autonomous drill rigs located at the respective mine site with which the mine site controller is associated. Activating the deactivation control transmits a deactivation command from the deactivation control to the control centre controller. The control centre controller forwards the deactivation command to a mine site controller associated with each mine site in the set of mine sites for distribution to all autonomous drill rigs at that mine site.

Abstract: Disclosed herein are an anti-stall control method and system for a tracked vehicle. The system includes a control module that includes a processor and a storage medium for storing computer programming code. The computer programming code defines a set of behaviour states including: a start state, a tramming state, and at least one corrective state. Each behaviour state has an associated set of behaviour controls for governing control of tracks of the vehicle. The computer programming code, executed on the processor, performs the method steps of: assigning an initial start state, wherein the tracks of the tracked vehicle are stationary; changing to the tramming state, on receipt of instructions to move the tracked vehicle, wherein tramming behaviour controls control the tracks of the tracked vehicle to operate in the same direction; and changing to a corrective states when corrective state conditions associated with that corrective state are satisfied.

Abstract: Methods and systems are described for tracking material through a production chain or operational process chain in which the material is transferred via a plurality of spatially distinct lumped masses of material (12, 14, 16, 18). A dynamic state space (430) is maintained descriptive of the plurality of spatially distinct lumped masses of material, wherein a quantity of entries in the dynamic state space is augmented or diminished dependent on a quantity of spatially distinct lumped masses being tracked. Measurements relating to an observed lumped mass of material are fused into the dynamic state space and a dynamic covariance matrix to provide an updated estimate of material in the plurality of spatially distinct lumped masses of material.
