HORIZONTAL DIRECTIONAL DRILLING SYSTEM WITH DRILL STRING BREAKOUT MONITORING
A drilling machine and operating method wherein a control algorithm evaluates a drill string joint-break routine. The operating profile of torque applied to the up-hole drill rod is monitored during energization of the break-out drive mechanism in the joint-break routine. Rotation at the rotational driver is also monitored during the joint-break routine, which is then characterized as normal or abnormal on the basis of the monitored operating profile of torque and the monitored rotational position change at the rotational driver. A break-out process for removing the up-hole rod from the drill string is interrupted and/or a message is provided to a display notifying an operator of an abnormal break-out.
