    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 them 2.

    What Are the Different Types of Mining Machines

    Conveyors are widely used mining machines used to transport materials within a mining area. Underground mines use belt conveyors to move ores from the drilling area to processing above ground. Large boring machines use conveyors that are attached to the drilling head moving along as the hole progresses and taking waste rock and ore away.

    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. In longwall mining the continuous miner cuts away long panels of coal and the ground is allowed to subside as the machine advances. This is known as controlled subsidence.
