CAUSE OF THE ACCIDENT
|
The direct cause of the accident was flyrock which was believed to come from angle holes that were drilled in face row holes. The primary crusher area was evacuated, but the road was blocked by the victims pick-up truck situated next to the primary crusher. The quarry superintendent told the blaster-in-charge that the primary crusher area had been evacuated and that the area was clear to blast. The blaster-in-charge could not see the primary crusher area and did not know that the superintendent and crusher operator had returned to the primary crusher area before the blast. A baseball size rock came through the victim’s windshield hitting the man in the side causing internal injuries to the kidneys, lungs and liver.

All personnel will be evacuated to the shop area and accounted for before future blasts.The blaster-in-charge’s license will be suspended for an undetermined time that has not yet been set by the Department. | |
