Parts of one Letcher County mine are shut down as officials try to correct several violations.
MSHA first inspected Sapphire Coal's Advantage Number One mine more than one week ago, citing safety hazards on 33 conveyor belts.
Inspectors visited again and found seven belts that were still not corrected.
The company was cited for eight violations, one for each belt and another for failing to comply.
United coal, who owns Sapphire, would not confirm or deny the violations, but say officials say they always work to correct any issues.
This year, MSHA has issued Sapphire Coal more than $120,000 in proposed penalties for more than two hundred code violations.
