For mining to be profitable, high quality ore needs to be found in a small area. Mining exploration is the term we use for finding out where the valuable minerals are. Today technology helps mining geologists and surveyors to find high quality ore without having to do any digging.
Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores.

Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.

The underground mining methods we use include room and pillar, narrow vein stoping and largescale 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.
