Muerte de Ledgeman/Hand en Kensington (Coeur Alaska Inc), AK, 7 de septiembre de 2011

The investigation is not complete, but as of now it appears a miner was fatally injured when material that traveled through a borehole struck him after a blast was initiated. The victim was on the 1290 level ramp waiting for a blast to be initiated. The concussion from the explosion traveled through a 3-inch borehole, blowing small rock and debris onto the victim.

Texto original en inglés de la MSHA

On September 7, 2011, Joseph L. Tagaban, blaster's helper, age 30, was killed when he was struck by rock and debris after a production blast was initiated. The rock and debris passed through a 3-inch diameter diamond drill hole that intersected the blast site. Tagaban was standing next to a tractor positioned on the uphill side of a haulage ramp near the 1290 crosscut. He was approximately 200 feet from the blast site and in line with the drill hole when the blast was initiated. The accident occurred because management policies, procedures, and controls were inadequate and did not protect persons from flying materials near the blast area. An old diamond drill hole, that intersected the blast pattern, had not been identified prior to initiating the blast. An adequate examination to check the area for hazards or to identify the diamond drill hole was not conducted prior to initiating the blast. Persons were not trained to be out of the blast area or in a location that would protect them from concussion, flying material, or gases. The blaster and blaster's helper were not provided with a blasting shelter or removed from the blast area to protect them from concussion and flying material.
