Mining industry requires high amounts of energy to extract and process resources, including a variety of concentration and refining processes. Using energy consumption information, different sustainability issues can be addressed, such as the relationship with ore grade over the years, energy variations in electricity or fossil fuel use. A rigorous analysis and understanding of the energy.

Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.

Suppose that an ore body with electronic conductivity is surrounded by sedimentary rock whose conductivity is dominated by ions in its water-filled pores, and that part of the body extends above the water table. The surface of the ore body below the water table is a boundary between media with different mechanisms of conductivity electronic and ionic, and a natural electrochemical reaction.

Ore is removed from the crust by mining, either on the surface open pit mining or underground shaft mining or room and pillar mining. Some minerals can be used in their natural form, for example sand in the building industry, phosphate rock for fertilisers and diamonds in jewellery.
