Abstract: A guidance system and method for guiding excavation at an excavation site utilizes an excavating machine and an in-pit crusher and conveyer (IPCC) having a first hopper and a second hopper for receiving material. The guidance system can receive first hopper data associated with the first hopper and second hopper data associated with the second hopper and can process the first hopper data and second hopper data to determine a selected hopper for dispensing material. In an aspect, the guidance system can generate a guidance indication to display to the operator of the excavating machine that indicates the selected hopper.

Abstract: A system for controlling operation of a first material engaging work implement includes a first machine, a second machine, and a controller. The controller is configured to store a kinematic model and characteristics of the implement system, determine a second machine operation zone, with the second machine operation zone being defined by a material movement plan of the second machine, and determine a current pose of the first machine. The controller is further configured to determine a first machine operation zone based upon the pose of the first machine, the kinematic model and characteristics of the implement system, and the second machine operation zone, with the first machine operation zone being spaced from the second machine operation zone, and generate a plurality of command signals to move the first material engaging work implement within the first machine operation zone between a first position and a second position.

Abstract: A computer-implemented method of responding to a missed cut during a pass made along a planned cut profile using an implement is provided. The computer-implemented method may include identifying the missed cut based at least partially on an implement position and a target cut point, predicting a performance value of the pass based at least partially on the missed cut and an implement load, and restarting the pass if the performance value is less than a minimum performance threshold and the implement load is less than a minimum load threshold.

Abstract: A material management system and method manages and tracks the progress of excavated material transferred through an excavation site by a conveyer system operating in cooperation with an in-pit crusher and conveyer (IPCC). The material management system distinguishes the material dispensed into the IPCC into identified material batches. To track the identified material batches, the material management system records data regarding the conveyer speed and the conveyer distance associated with the IPCC, as well as possible other data regarding the identified material batches. The material management system processes this to track the indentified material batches along the conveyer route.
