उत्तर
Rock salt is mined just like coal.
Explanation:
Rock salt is found in large underground deposits formed by the drying up of ancient seas. It is extracted using heavy machinery through traditional underground mining methods, such as room-and-pillar mining. This process of drilling and blasting solid blocks from the earth is identical to how coal is extracted.
