    THE COAL RESOURCE World Coal Association

    Underground Mining There are two main methods of underground mining room-and-pillar and longwall mining. In room-and-pillar mining, coal deposits are mined by cutting a network of rooms into the coal seam and leaving behind pillars of coal to support the roof of the mine. These pillars can be up to 40 of the total coal in the seam.
