Abstract An improved visibility system was developed for use on the large (100 ton+) haulage trucks typically operated in open pit and surface mines. The improved visibility system provides the truck driver with a means of viewing hazardous situations that occur in the extensive blind areas adjacent to his truck. The cost effective, reliable, visibility system consists of a closed-circuit television, three unique fresnel viewers, and two improved mirrors. This report describes the visibility problems of large trucks in the surface mining environment, shows the performance of existing mirrors, substantiates concept selection, and describes the prototype improved visibility system.
