The paper concerns itself largely with the operational benefits which fall conveniently into two parts: productivity benefits and ergonomic benefits. To put these into perspective, however, a brief look is first taken at the evolution of rock drilling. Benefits from a productivity point of view and their causes are then discussed, with a detailed examination of increased penetration rates, improved drill steel life, similar maintenance costs, lower energy consumption, efficient energy transmission and reduced overall costs. Next to be looked at are ergonomics or the science of having both machine and environment at optimum levels for the worker's health, comfort and safety. Benefits discussed here are lower noise levels, oil-mist-free conditions, automation of controls and reduction of vibration, etc. This higher technology, however, cannot be utilized properly without a deeper level of training, particularly of maintenance staff. Notwithstanding all the foregoing, pneumatic drilling technology is here to stay and the paper concludes with a brief comparison of the two technologies as a reminder of this. /Author/TRRL/
