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.

Open-pit Mining: A Definition and Guide

Open-pit mining is a non-tunnel mining process providing direct access to minerals and stones close to the Earth's surface. This method of mining involves the use of explosives to create large, canyon-like holes, which are then refined into workable pits using heavy machinery. The open-pit mining process is often done in a step-like fashion.
