Types of Coal Mining

The underground method of coal mining currently utilizes two main techniques: room and pillar mining, and longwall mining 1. Room and pillar mining involves cutting a system of rooms within the coal seem. Pillars are left in order to support the roof of the cut into coal seem. In a secondary mining method, called retreat mining, coal is systematically collected from the pillars, allowing the mine to close in behind
