Between 1992 and 1998, over 29
fatal accidents occurred during dumping operation of off-highway trucks on
the waste dumps in open pit and quarry mining operations. Of these fatal accidents,
four occurred in 1998. The fatalities during these accidents occurred when
a given truck got too close to the edge of the spoil dump and the ground underneath
truck gave away or the truck went over the edge (in some instances over the
berm). To improve the safety of dumping operation of off-highway trucks, a
research project involving use of on board GPS receivers to locate the relative
position of a given truck with respect to the edge of a dump was proposed
to NIOSH in early 1999. The first phase of this project was funded by the
1999-2000 budget, which started on September 1, 1999. Research results indicate
that these accidents can be prevented by knowing exact location of the truck
with respect to the edge of the spoil dump through a on board GPS system.
The display of a map showing exact travel path and the location of a given
truck with respect to the spoil edge or unsafe ground conditions will aid
the truck driver in judging imminent hazards.
Abstract
A dump edge and vehicle proximity warning system is being developed at the Colorado School of Mines using GPS and wireless local area networks to improve the safety of off-highway trucks in open pit mines. After two years of research, software development, and testing in the laboratory, field tests are currently being carried out at operating limestone quarries and open pit mining operations to evaluate the effectiveness of the system under rugged operating conditions.
