The Chinese word 矿工 (kuànggōng), meaning "miner", is formed through a straightforward semantic compound method common in Mandarin. It combines the character 矿 (kuàng), which means "mine" or "ore", with the character 工 (gōng), which means "worker" or "laborer". The first character 矿 specifies the domain or material, while the second character 工 denotes the person's profession, creating a precise and easily understood term for a person who works in a mine.
