Abstract:
The present disclosure provides an apparatus for treatment of mined material. The apparatus comprises a source for generating electromagnetic radiation and a microwave inlet region for exposing fragments of the mined material to the electromagnetic radiation. Further, the apparatus comprises a reflective structure adjacent the microwave inlet region and providing, or surrounding, a passage for guiding the fragments of the mined material to the microwave inlet region. The reflective structure is arranged to attenuate penetration of the electromagnetic radiation from the microwave inlet region into the passage during throughput of the fragments of the mined material.
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 an 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:
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:
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.
Abstract:
A continuous process provides direct reduction of iron ore in a solid state. Briquettes of iron ore fragments and biomass are transported through a preheating chamber and preheated to a temperature of at least 400° C. The preheated briquettes are transported through a heating/reduction chamber that has an anoxic environment, and iron ore and biomass in the briquettes are exposed to electromagnetic energy in the form of microwave energy under anoxic conditions. Microwave energy generates heat within iron ore, and biomass acts as a reductant and reduces iron ore in a solid state, as the briquettes move through the heating/reduction chamber.
Abstract:
A mining system for directing mine operations including a flow planner and a dispatcher. The flow planner receives operating parameters and global mine data and calculates a flow plan based on the operating parameters and the global parameters. The dispatcher then determines dispatch assignments based on the flow plan from the flow planner, and effects a dispatch of mining equipment based on the dispatch assignments.
