Coal Mining –The 2 Most Basic Techniques Of

2018-3-25  Because most of the coal is found just under the surface, reclaiming the land after the closure of mine is far simpler. The different types of surface mining that can be used are: 1. Strip mining 2. Auger Mining 3. Open-pit mining 4. Mountain removal mining The second fundamental method of extracting coal is underground mining. This technique is used when the coal is buried deep inside the earth. The machines used for this type of coal
