Abstract: A method for improving the efficiency of a mining operation includes obtaining measurements of at least two of: a volume of mined material removed from terrain by an excavator; a volume of the mined material carried in a bucket of the excavator after removal of the material from the terrain; and a volume of the mined material deposited by the bucket in a truck tray. The method includes alerting an operator of the excavator to a possible spillage or carry-back condition if a difference between the at least two volume measurements exceeds a threshold value. Another method includes determining an optimum dipper trajectory in response to measurements of a height and radial profile of a terrain bank, a position of the excavator relative to the bank and a target volume of material to be extracted into a bucket of the dipper during the dig cycle.
