Noise is a generic hazard common to all commodities and, to a greater or lesser extend affecting, all operations within mining. More people are exposed to the risk of noise- induced hearing impairment than to any other occupational hazard. Pneumatic percussion drills are a major contributor to noise-induced hearing impairment in mines. The design and development of a quiet, self-thrusting blast hole drilling system will reduce this risk. During this project such a drilling system was developed, tested and demonstrated. The primary output of this project is a quiet, ergonomically, reliable blast hole drilling system, which is used to drill suitable blast holes by workers responsible for drilling these holes. The system has to be safe and reliable with reduced hearing loss and higher productivity
