MINE HAUL TRUCK PERFORMANCE METRIC MANAGEMENT SYSTEM ANS METHOD

摘要

Disclosed are various techniques to optimize mining operations efficiency in which the mine utilizes mine trucks over a mine route. One such technique includes optimizing engine speed from a speed and torque management system. Such engine speed changes can be determined using information such as road grade data and mine stop locations, or whether the engine is in a retarder mode. Mine operation efficiency can be improved through use of adjustments made to a load acceptance curve. Changes to the load acceptance curve can be made through use of information such as road grade data and target truck speed. Improvements can be made through dynamically adjusted vehicle speed, such as through average route speed adjustments, or route segment adjustments in light of average route speed. A dynamic torque management system can provide efficiencies as limits are applied to torque using look ahead information.
