Abstract
A single-boom roof bolting machine was outfitted with measurement and recording systems to detect changes in machine parameters while drilling. The purpose of the instrumented bolter was to detect changes in roof conditions from the machine parameters of penetration rate, thrust, rotation rate, torque, reflected light from rock cuttings, and vibration of the roof during drilling. The system was demonstrated underground in coal mine conditions and showed correlation between rock type and drilling parameters.
