2 Underground Mines: These are situated inside the earth's surface, and can be deep up to 100-150 ft. They require a continuous exhaust system to remove the harmful and poisonous gases, In Underground Mines, there is always a certainty of Mines collapse due to the presence of Flammable gases inside like CH4, it becomes very risky to work in such conditions.

So, Underground Coal Mining is More dangerous as compared to Opencast Mining.
