Coal mining equipments

The goal of coal mining is to remove coal from the ground. Coal is valued for its energy content, and since the 1880s is widely used to generate electricity. Most coal seams are too deep underground for opencast mining and require underground mining, which method currently accounts for about 60% of world coal production. Coal is mined commercially in over 50 countries. Over 7,036 Mt/yr of hard coal is currently produced, a substantial increase over the past 25 years.

Floation have used in coal recovery for many years. Before the usage of fully mechanized coal mining, the larger coal used to be taken but the coal finer were left as tailings. However, today, factors like need of energy, high cost of coal prices caused new methods to be applied to gain finer coal. Another reason of coal flotation is the environmental aspect. Today, because of the environmental laws, the coal can't be driven out before a washer unit. So, for about twenty years new methods and technologies are being developed in the coal-cleaning unit.
