Coal Mining –The 2 Most Basic Techniques Of Extraction

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 extraction can excavate at depths of more than thousand feet. The coal itself is cut out from rocks using machinery. It is brought to the top using massive conveyor

Coal Mining Data Model Industry Models ADRM Software

Longwall mining involves the extraction of coal from a section of the seam or 'face' using mechanical shearers. The coal 'face' can typically vary in length from 300-1,000 feet. Self-advancing, hydraulically-powered supports temporarily hold up the roof while the coal is extracted.
