Coal
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Hydrocyclone Working Principle
The apex is the discharge point of the cyclone, this discharge is referred to as the UNDERFLOW. The material that exits at this point will be the material that requires further grinding. The last part of the cyclone is the cyclone SKIRT. It is there only to limit spillage and splashing it isn't important to the operation of the cyclone.
