Abstract
A drilling system includes a control system that monitors operating parameters so as to protect the drilling machine from damage and increases drilling operation efficiency. A method of using a hydraulic system of a percussive drill as a sensing system includes sensing a drill bit blow-out event by measuring changes in the operating hydraulic fluid pressure in the hydraulic system used to operate the percussive drill.
