The following report is the product of our Cooperative State partner and is presented here in its original unedited form from the state. The findings and conclusions in this report are those of the individual Cooperative State partner and do not necessarily reflect the views or policy of the National Institute for Occupational Safety and Health.
A 58-year-old man with many years of mining experience had been driving a haul truck for only a couple of weeks before he was crushed under it in the autumn of 2004. The loaded haul truck he was driving had a gross vehicle weight rating of approximately 63 ton (57 tonne), including its maximum payload of 35 ton (31.8 tonne). The truck went off the left (pit) side of the haul road and continued downhill across a slope covered with loose rocks. The driver was ejected or jumped and was pinned under the front left corner of the haul truck cab as the truck came to rest on its left side. The truck’s braking systems were not well maintained and lack of seat belt use contributed to this miner’s death.
