  • Systems and methods for drill head position determination
    Patent number: 11401754
    Abstract: Systems and methods for drill head position determination are disclosed. A method for determining a position of a drill head of a drilling machine may include: retrieving a stored rotational position of at least one sheave and a stored position of the drill head; measuring the rotational position of the at least one sheave using a sheave sensor; initially calibrating the rotational position of the at least one sheave before the drill head moves; dynamically determining the position of the drill head based on the rotational position of the at least one sheave while the drill head is moved; and storing the rotational position of the at least one sheave and the position of the drill head during a shutdown event of the drilling machine.
    Type: Grant

  • Underground mining machine
    Patent number: 10046944
    Abstract: A system for managing an underground mining machine is disclosed. The system may include a reel-in switch located in an operator station configured to generate plurality of reel-in signals, and a reel-out switch located in the operator station configured to generate a reel-out signal. The system may additionally include an electronic controller in electrical communication with the reel-in switch and the reel-out switch. The electronic controller may be configured to receive the plurality of reel-in signals from the reel-in switch and enter into two or more reeling-in modes in response to the plurality of reel-in signals.
