Kentucky recorded its first coal mining death of the year when a 29-year-old miner was killed in a conveyor belt accident in an underground Harlan County mine. Hubert Grubbs was working in the D11 Panther Mine in Cumberland. He was splicing a conveyor belt early Wednesday morning when it started unexpectedly, causing fatal injuries. The mine was shut down after the death and inspectors have issued 15 state citations for non-compliance. The coal mine death was the country’s fourth this year.
