With the ever rising demand for the minerals and metals, the need for surface mining is increasing and has lead to a direct positive effect on the surface mining market. According to EIA the world coal consumption is increasing at the rate of 1.3% per year, which is extracted mostly from the surface and the underground activities. As per the report of Hartman and Mutmansky (2002), in USA the surface mining contributes about 85% of all mineral exploitation (metallic ore 98%, non metallic ore 97% and coal 61%). Beside coal, the demand for other minerals and metals such as gold, chromium, nickel and iron ore is also rising, hence we can think of the overall positive impact on the surface mining market.
The surface mining market can be segmented on the basis of methodology, minerals extracted, and the geographical locations of the surface mining regions and companies. According to the technology involved, the surface mining can be classified as strip mining, mountain removal mining and open pit mining. Strip mining is applied when the mineral deposits and the surface of the ground are near to each other.
Mountain removal mining is a kind of surface mining that involves the mining of the summit ridge of a mountain. Open cast or the open pit mining is the method of removal of ores and minerals from a pit. Open cast mines that produce dimension stones and the building materials are called quarries. According to the mineral extracted mining can be divided as the metallic ore mining, non metallic ore mining and the coal mining. Metallic ore mining involves extraction of zinc, gold, silver, copper, lead and others. Non metallic ore mining involves extraction of lime, salt, phosphates and others.
