ST. CLAIRSVILLE, OH (WOWK) — Ohio Valley coal giant Robert E. Murray died Sunday morning, according to a high-level source in the West Virginia coal industry. He was 80 years old.

The former coal miner, mining engineer, company founder, and philanthropist was surrounded by his family when he passed early Sunday morning.

The news of his death comes just days after the coal giant announced his retirement as chairman of the board of directors of American Consolidated Natural Resource Holdings Inc. Murray Energy Holdings emerged last month from federal bankruptcy under a new name. The new company is now the largest privately-owned U-S coal operator.

The former CEO recently filed for black lung benefits, saying he was heavily dependent on oxygen and “near death.”

Shortly after the announcement of Murray’s death, many took to social media to share their condolences, including a tweet from West Virginia Senator Shelley Moore Capito (R) and West Virginia Attorney General Patrick Morrisey.

Early Monday morning following Murray’s death, Ohio Governor Mike DeWine issued the following statement on the death of Bob Murray:

Fran and I have lost a dear friend. Bob and Brenda have been our friends for three decades. We extend our sympathy to her and to their wonderful family. Bob fought through his medical challenges with the same energy, drive, guts, and faith in God as he approached everything in life. In any conversation I ever had with a Bob, he always talked about three things: his faith in God, his love of Brenda and their children and grandchildren, and his dedication to his employees. He has fought the good fight. We will deeply miss him.

Ohio Gov. Mike DeWine (R)
