DRILL AUTOMATION CONTROL SYSTEM |
摘要 |
A rotary blasthole drilling apparatus comprises a rotary blasthole drill (2, 4, 6) and a drill automation control system. The apparatus includes a pull-down motor (42) and a drill motor (44). The pull-down motor (42) is driven by a pump (72) to provide a pull-down force to a drill string (2) and drill bit (4). The drill automation control system includes a user interface (62) through which an operator sets a rotary torque set point that determines an amount of torque applied to the drill bit (4) by the drill motor (44). The control system further includes a detector (70) for detecting pressure in the pump (72) during a drilling operation, and a processor (79) which is operative under the control of a program (80) stored therein and responsive to the rotary torque set point (68) and signals from the pull-down pressure sensor (70) for generating an error signal.
