1. A system for controlling an electric mining shovel, comprising:

  • a processor adapted to;

    determine a profile of a digging surface responsive to a scan of the digging surface;

    identify a predetermined bank profile from a plurality of predetermined bank profiles, the identified predetermined bank profile a closest match of the plurality of predetermined bank profiles to the profile of the digging surface;

    determine a first electric mining shovel digging procedure based upon the identified predetermined bank profile;

    execute an optimization routine to determine a second electric mining shovel digging procedure;

    compare the first electric mining shovel digging procedure to the second electric mining shovel digging procedure to determine an preferred electric mining shovel digging procedure;

    provide the preferred electric mining shovel digging procedure to the electric mining shovel, the preferred electric mining shovel digging procedure adapted to, responsive to an automatic relocation of the electric mining shovel, automatically control a cable reel to change an extended length of an electrical cable utilized to provide power to the electric mining shovel; and

    execute a confusion routine responsive to a determination that a bank of said digging surface is unstable, said confusion routine adapted to request at least partial operator control of said electric mining shovel.
