Abstract: A method is provided to coordinate loading of a material in an operational area by machine actors including haul trucks and loading vehicles. The method implements quick and efficient loading of trucks with the material in order to ensure that they are highly utilized. A vehicle coordination assembly is provided to establish data communications with vehicle sensing systems of the haul trucks and of the loading vehicles and determine load-ready haul trucks. For each load-ready haul truck, a loading task is assigned to two or more of the loading vehicles for loading of the load-ready haul truck. Each task specifies a respective safe operating space in which a loading vehicle is restricted to operating. The assigned loading vehicle with a safe operating space extending over a side of the haul truck can only perform a dumping operation to the haul truck at any one time.

Abstract: A system for mining material in a seam under an overburden layer using a geological model map of a geological formation, including a desired drilling end point at a predefined position relative to a geological boundary between the overburden layer and seam. A drill controller controls operation of a drill drilling a blast hole. A sensor pack senses, while drilling the blast hole, blast hole drilling operation parameters; and feeds the sensed parameters in real time to the drill controller. A data storage module stores a geological model of the geological formation and sensed parameters data. A processor module generates a geological model map including the desired drilling end point and locates the drill bit position relative to the geological boundary and such end point. The drill controller drills to the desired drilling end point and causes the drill to stop drilling upon reaching such end point.

Abstract: A process for direct reduction of iron ore in a solid state includes exposing briquettes of iron ore fragments and biomass to electromagnetic energy under anoxic conditions and generating heat within iron ore in the briquettes. The iron ore is reduced in a solid state within the briquettes, and the biomass provides a source of reductant.

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: A method 10 of refurbishing a bucket wheel reclaimer (BWR) 41 having structural frame 68, a chute 66 supported by the structural frame 68, a yard conveyor 42 for receiving material from the chute 66 and an impact table 64 supported by the structural frame 68 below a portion of an upper run 44 of the yard conveyor 42. The method includes a step 12 of decoupling a current impact table 64 from the BWR structural frame 68. The impact table 64 is lowered at step 26 from the structural frame 68. Thereafter at step 14 the current impact table is moved laterally away from and to one side of the yard conveyor. At steps 16 and 18 a fresh impact table is moved laterally to a location beneath the upper run 44 of the yard conveyor and coupled to the BWR 41.

Abstract: A method is provided for operating a railway network having a number of trains, the method comprises operating a scheduling machine that is in communication with the railway network over a data communication system, to receive time separated state data defining states of the railway network at respective times. The scheduling machine accesses a model of the railway network that is stored in an electronic data source. The model defines locations in the railway network that allows for passing of trains and paths for journeys of each of the trains. The method includes operating the scheduling machine to apply the state data to the model to determine, at each of the respective times, controls associated with each trains' path for each of the trains. The scheduling machine is operated to determine the controls by optimizing a objective function for the trains, such as minimizing total travel time of the trains, taking into account the locations in the network, positions of the trains and paths of each of the trains. The controls are transmitted, via the data communication system, to control movement of the trains, for example by operation of railway network switches (points) and signal lights, through the railway network based on the controls.

Abstract: Described herein is a method and system for classifying rock types in a rock body. The method comprises the steps of obtaining spectral data from a spectral measurement (202) of a surface region of the rock body and then determining a first spectral ratio between two wavelength bands of the spectral data. From the first spectral ratio it can be assessed (204) whether the measurement is a high-angle measurement, and if the measurement is not a high-angle measurement then a further spectral ratio between two further wavelength bands of the spectral data is determined (208). The further spectral ratio is then compared (210) with a corresponding diagnostic criterion to assess whether the surface region comprises a first rock type associated with the further spectral ratio and diagnostic criterion.
