    The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
