Blasting accident at a surface mine Monday night at the Cam Mining, mine number one near Elkhorn Creek in Pike County.
Tuesday investigators shut the mine down while they investigate how this happened.
State mining officials say witnesses to the accident told them there were two blasts both happening at the same time and both shot less than one hundred feet apart from each other.
Investigators say a group of mechanics was working on equipment nearby.
Officials say the blasts sent rocks and other debris flying towards them with no notice.
The victim is identified as 40 year old Bobby Messer of David in Floyd County.
Officials say he worked there for ten years.
Authorities say he was hit in the head. No one else was injured.
The surface mine is closed and all blasting in the area is suspended until the investigation is complete.
Both state and federal investigators spent all day at the mine going over the blasting and accident sites and interviewing witnesses and other employees trying to figure out what went wrong when the shots were detonated.
WYMT’s Angela Sparkman also talked with Cam Mining officials, but they couldn't release any information.
They hope to have more information when the investigation is complete.
