• Description:
  Powered haulage has been, and continues to be, a major source of severe accidents, injuries, and fatalities at metal/nonmetal surface mines. Between 1986 and 1997, truck drivers accounted for 63% of the lost-time injuries in surface haulage. This project was undertaken to reduce the number and severity of lost-time injuries among operators of these trucks. Shock accelerations were measured on trucks at a western surface mine during representative work cycles to determine the shock environment of the operator. Acceleration data was collected from the floor and seat of two types of haulage trucks. Shock tests were also run at Caterpillar, Inc.'s, proving grounds in Green Valley, AZ, to determine the magnitude of shocks resulting from a rough road and from occasional loading events. A controlled rock drop onto the bed of a haulage truck and a side impact were measured. A system that ties acceleration data with Global Positioning System (GPS) data was developed to aid in identifying haul road problems. A biomechanical investigation revealed that a side impact will cause the erector spinae muscle groups on the side opposite to contract first. Then the near side muscles react approximately 20 ms later, which could increase the likelihood of injury from a side impact. [Description provided by NIOSH]
