Coal Types, Formation and Methods of Mining

Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. In continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and blasting. Another type of continuous underground mining is called longwall mining.
