- Abstract
- Early in 1975 a policy decision was made to improve the fire patrol system as a means of fire detection on Hartebeestfontein Gold Mine. The ionization detector head system known as the 'BECON' type with a telemetering system had at the time been developed to such a degree of reliability by the Anglo American Electronics Laboratory, and the decision was made to install this system on Hartebeestfontein Gold Mine. The two main advantages of the 'BECON' system were that it ensured the early detection and quick pin-pointing of a fire. There was little doubt, and was subsequently proved on numerous occasions, that these two factors invariably resulted in early extinguishing of underground fires.
