Methods and Systems for Operating a Vehicle Subject to a Travel Restriction
23 Feb 23
Systems and methods of operating a vehicle subject to a travel restriction determine when the vehicle is traveling in an unloaded state; determine a speed of the vehicle when the vehicle is traveling in the unloaded state to produce an actual travel empty speed; compare the actual travel empty speed with an historical travel empty speed for the vehicle; and determine that the vehicle operation is subject to the travel restriction when the actual travel empty speed is less than a predetermined percentile of the historical travel empty speed.

Methods and Systems for Operating Vehicles to Reduce Bunching
23 Feb 23
Systems and methods of operating vehicles to reduce bunching of the vehicles when traveling on a roadway determine an intra arrival time for two consecutive vehicles traveling on the roadway; calculate a virtual spacing between the two consecutive vehicles based on the intra arrival time; determine a following distance threshold; compare the virtual spacing between the two consecutive vehicles with the following distance threshold; determine that the two consecutive vehicles are in a bunched condition when the virtual spacing between the two consecutive vehicles is less than the following distance threshold; and control at least one of the two consecutive vehicles until the vehicles are no longer in the bunched condition.

System and method for adjusting leaching operations based on leach analytic data
6 Dec 22
The method may comprise receiving historical data (e.g., mineralogy data, irrigation data, raffinate data, heat data, lift height data, geographic data on ore placement and/or blower data); training a predictive model using the historical data to create a trained predictive model; adding future assumption data to the trained predictive model; running the forecast engine for a plurality of parameters to obtain forecast data for a mining production target; comparing the forecast data for the mining production target to the actual data for the mining production target; determining deviations between the forecast data and the actual data, based on the comparing; and changing each of the plurality of parameters from the forecast data to the actual data to determine a contribution to the deviations for each of the plurality of parameters.
