Which code does this activity belong in?
Establishments in this industry extract bituminous coal using underground mining methods, develop underground bituminous coal mine sites, and perform beneficiation activities such as cleaning and washing. The distinction from Bituminous Coal and Lignite Surface Mining lies in the extraction method; surface mining operations belong in the latter code regardless of whether they also perform beneficiation. Anthracite Mining is a separate classification for underground and surface mining of anthracite coal rather than bituminous coal.
