California enforces its own mining and tunneling regulations through Cal/OSHA’s Mining and Tunneling (M&T) Unit. The main function of this specialized unit is to investigate complaints and accidents in mines and tunnels and to issue citations to employers that violate regulations. The M&T Unit also conducts pre-job safety conferences and issues permits prior to the commencement of underground mining or tunneling. The M&T department also conducts random/periodic inspections of tunnels, underground mines, and surface mines and quarries.

The M&T Unit has a specialized mine safety training offered free for mine operators and employees. The safety training is geared to provide education to new miners and refreshers to experience miners.

The M&T Unit offers free classes in Sacramento and San Bernardino. The classes include training in educating miners in 30 CFR parts 46 and 48 New Miner Training; 30 CFR parts 46 and 48 Newly Hired Experienced Miner Training; and 30 CFR parts 46 and 48 Annual Refresher Training for surface mining.
