  • First haul truck - a 29-year old contract miner with 3 years of total mining experience and 4 weeks of experience at the mine was fatally injured in a powered haulage accident. The accident occurred as the victim was dumping spoil material on the H Pit Level, of the Joe Day Branch area of the mine site. The victim was operating a Caterpillar 777B rock truck when he backed over the dump point and continued down the slope for approximately 140 feet. The truck broke into two pieces, and came to rest with the cab of the truck facing up the slope and the bed upside down facing down the slope. The victim was ejected from the truck and sustained fatal injuries. 2 nd haul truck – driver had 8 weeks of experience, but he was wearing his seatbelt. He was operating a 240 ton Leibehr coal truck. When extricated from the cab, he was still strapped into the seat. It is estimated that the haul truck was airborne for at least 50 feet before it struck the slope, broke in two, then traveled another 150 feet on it’s top. The seatbelt kept the operator in the cab and prevented him from being ejected, which saved his life. He had very minimal injuries and basically walked away from the accident scene.
  • Truck was heading to the dump, fully loaded and operator fell asleep. Truck climbed an 8 foot berm and then rolled once down a 130 foot drop.
  • When rescuers reached the truck, the operator was still belted into seat. The operator received no injuries and walked away from the wreck. Notice the cab is still intact with no damage. The windshield was busted out after the incident by the rescuers so that the driver could be extracted safely.
  • March 22, 2010. Haul truck hauling bentonite to the plant got off the road and rolled on it’s side. Truck was traveling less than 30 mph. There was a driver who was a trainee and a passenger who was the trainer. Who was wearing their seatbelt and who survived this roll over?
  • When asked why he wasn’t wearing a seatbelt, the driver stated, “well, the trainer wasn’t wearing his, so I thought it was ok not to wear mine….normally I always wear my seatbelt…..” The driver did not sustain any injuries and was found standing in the middle of the road by the EMS personnel who responded to the 911 call.
  • Yes, he did. How ever he made it under the bumper of the 793 haul truck, it was his seatbelt that kept him in place so that when the rest of the truck was destroyed, the driver’s seat was left virtually untouched. If he hadn’t been wearing the seatbelt, he would have been thrown into the path of either the steering arms, front tire or engine oil pan.
