1. A computer-readable medium, the computer-readable medium being non-transitory and including program instructions for drilling a borehole that, when executed by one or more processors of a computer system operatively associated with a drill rig, cause the one or more processors to carry out the steps of:

  • initiating a drilling phase;

    monitoring a drill parameter during the drilling phase, the monitored drill parameter comprising at least number of drill retractions;

    determining whether the monitored drill parameter is within a predetermined specification for the monitored drill parameter;

    choosing a drilling phase defect mitigation routine based on the monitored drill parameter when the monitored drill parameter is outside the predetermined specification;

    implementing the drilling phase defect mitigation routine; and

    resuming the drilling phase.
