    What is Longwall Mining? (with pictures) - wiseGEEK

    Jan 30, 2021  In mining regions deeper than 1,000 feet (300 meters), the room-and-pillar method becomes highly uneconomical because the size of pillars required to support the roof are much larger, meaning that valuable coal cannot be extracted from them. Longwall systems make deep mining feasible.
