A place where coal or other minerals are mined, or the entire operation including buildings and equipment used in mining.
From Anglo-Norman 'colerie,' derived from 'cole' (coal) with the '-ery' suffix meaning 'place of.' First documented in English around the 14th century as coal mining became industrialized.
The word 'colliery' reveals how English borrowed French administrative terms for industrial operations—we didn't create new words from scratch, but adapted existing trade vocabulary when new industries emerged.
