RICHMOND, VA (WWBT) - It's been nearly two months since the mine explosion killed 29 men - now inspectors want to know what caused the blast.
No one has been able to re-enter the mine since rescuers removed the final victims bodies in April. Toxic and explosive gases have kept inspectors out.
A team of 16, made up of federal and state regulators along with representatives from the Richmond-based company that owns the mine, will try to enter Wednesday and determine what went wrong.
Government investigators suspect methane gas and coal dust caused the massive explosion.
This mine has a spotty safety record. According to federal records, there were three other deaths in the past 12 years.
The blast sparked new inspections into West Virginia's mines.
More than 100 citations were handed out during an inspection blitz ordered by Governor Joe Manchin days after the explosion.
