Methods and systems for drilling boreholes
First Claim
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.

Abstract
A computer-readable medium including program instructions for drilling a borehole. When the program instructions are executed by one or more processors of a computer system operatively associated with a drill rig, the program instructions cause the processor to carry out the steps of initiating a drilling phase and monitoring a drill parameter during the drilling phase. The drill parameter includes at least one of drill rotational speed, drill torque or number of drill retractions. The program instructions further cause the processor to carry out the step of determining whether the monitored drill parameter is within a predetermined specification for the monitored drill parameter in order to choose a drilling phase defect mitigation routine. After implementing the drilling phase defect mitigation routine, the processors carry out the step of resuming the drilling phase.

34. A non-transitory computer readable medium storing program instructions for drilling a borehole that, when executed by a computer associated with a drill rig, cause the computer to carry out the steps of:
-
after initiating a drilling phase, performing a collaring routine to form a collar in the borehole, said collaring routine comprising a first phase collaring routine and a second phase collaring routine, said second phase collaring routine beginning after contacting competent ground in the borehole; monitoring drill parameters associated with the drill rig comprising drill rotational speed, drill torque, drill depth, hoist speed and number of drill retractions; determining whether at least one drill parameter is within a predetermined specification for at least one monitored drill parameter during the drilling phase and the retraction phase, the retraction phase following completion of the drilling phase; and implementing a drilling phase defect mitigation routine when the at least one drill parameter is outside the predetermined specification for the drilling phase; and implementing a retraction phase defect mitigation routine when the at least one drill parameter is outside the predetermined specification for the retraction phase.
