Commonly used mining techniques to extract coal
Underground mining is more widely used to extract coal compared to opencast mining, as many coal seams are said to be found deep below the earth surface. The underground mining includes six type of mining methods that include longwall mining, continuous mining, room and pillar mining, blast mining, shortwall mining and retreat mining.

Coal Mining and Production
Strip mining is one of the most economical surface processes. Here removal of overburden and coal extraction proceed in parallel strips along the face of the coal deposit, with the spoil being deposited behind the operation in the previously mined areas. In open pit mining, thick seams (tens of meters) are mined by traditional quarrying techniques.

The Mining Process | Introduction | underground COAL
The Mining Process. Once a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc – see Access to Seam from

What is the process of coal mining? – MVOrganizing
What happens to coal after it is mined? Processing coal After removing the coal from the ground, the miners may send it to a preparation plant near the mining site. The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials. This process increases the heating value of the coal.

The coal mining life cycle
Mine development. Coal can be extracted from the earth either by surface mining or underground mining. In open-pit coal mining, a pit is dug in an area and this pit becomes the open-pit mine, sometimes called a quarry. Open-pit mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting becomes too great.
