Relating to ventilation of underground mines

Summary

The bill rewrites West Virginia’s mine‑ventilation law, requiring specific amounts of fresh air at key points in underground coal mines and setting limits on oxygen, carbon dioxide and other gases. It applies to mine operators and foremen, who must install and maintain flame‑resistant brattice, keep crosscuts spaced no more than 105 feet apart, and provide safety‑committee access to airflow‑measuring tools. The goal is to improve miner safety by ensuring harmful gases and smoke are diluted and removed.
