West Virginia officials have issued 253 violations in the Upper Big Branch mine disaster.
They're targeting two foremen, whose failures may have contributed to the conditions that killed 29 men in 2010.
The violations are included in a report released today.
Officials with the West Virginia Office of Miners Health Safety and Training presented the report to the victims' families at the Beckley-Raleigh County Convention Center this morning.
The findings were reported privately, before they will be released publicly this afternoon during a state Board of Coal Mine Health and Safety meeting.
It's the fourth and final report on the tragedy at the former Massey Energy mine.
All officials conclude Virginia-based Massey let methane and coal dust build up in the mine.
Worn and broken cutting equipment created the spark it needed to explode.
This comes a day after federal prosecutors charged the former superintendent with fraud.
And signaled they are going after other managers.
