Combining contract and in-house research, the Bureau of Mines has developed and in-mine tested a novel device to improve the field-of-view of operators of off-highway mining equipment. This device utilizes a downward-looking, flat fresnel lens. The lens, plus louvers to reduce glare, is housed in a protective steel structure. The complete unit is called a blind area viewer. The viewer, when mounted on the right-front corner of the deck of most large haulage trucks, will increase a driver's direct field-of-view from about 35 pct (of where he/she has to drive) to about 80 pct. The improved visibility allows the driver to see possible collision hazards and roadway obstacles better, thus improving mine safety and increasing productivity.
