- "On March 18, 2023, a miner died when the mine roof collapsed during the installation of standing roof support (crib) as part of the longwall recovery cycle. The accident occurred in an area adjacent to a longwall shield.
Best Practices:
Follow the approved Roof Control Plan.
Design, install, and maintain roof support where miners work or travel.
Never travel or work under unsupported roof.
Conduct a visual examination of the roof, face, and ribs immediately before starting work in an area.
Be alert to changing roof conditions, especially during longwall recovery."
