DRENNEN, W.Va. (WOWK) — Rescue efforts are underway after a miner got trapped following a sudden flooding about 3/4 of a mile under the mountain at the Rolling Thunder Mines in Drennen on Saturday.

Nicholas County Commissioner Garrett Cole said on Facebook that around 1:30 p.m., it was reported to Nicholas County Homeland Security and Emergency Management that miners struck an unknown pocket of water, which quickly rushed the section.

One miner is currently missing and believed to be trapped. Cole said crews began pumping water out around 9:30 p.m. Saturday night, trying to locate the miner, though the amount of water that needs to be pumped is not known.

All other miners are accounted for. Search and rescue efforts continued overnight.

Cole said Nicholas County Homeland Security is on standby with an underwater drone once enough water is pumped out to possibly locate the miner and establish communication.

Governor Patrick Morrisey said the West Virginia Office of Miners’ Health, Safety, and Training is coordinating with mine safety officials, the West Virginia Emergency Management Division, the West Virginia Department of Environmental Protection, the West Virginia State Police, the federal Mine Safety and Health Administration (MSHA) and local emergency responders. He also said the West Virginia Emergency Management Division is coordinating with the National Cave and Rescue Commission.

Access to the area is currently restricted.

“If specific needs arise, we will promptly share verified information regarding how and where help may be directed. Until then, we respectfully ask the public to keep the crews, the affected family, and all involved in your continued thoughts and prayers,” the Nicholas County Commission said in a statement.

This is a developing story.
