Open Pit and Underground Mining of Coal - Tanzania Crusher
In coal mining, the coal mining method can be divided into two styles: open pit and underground mining of coal. As a principle, open-pit method is considered to be much more approvable and dominant than Underground, especially in recovery, production capacity, grade control and cut off grade, ore lose and dilution, flexibility, safety, and so on. Even though,open pit and underground mining of coal,Underground versus Open Pit Mining Firwin Corporation. There are open pit mines all over the world and they yield everything from clay and coal to uranium and gold.
