Coal remains a dominant source of electricity generation, a fuel for iron and steel production, an important entity among road construction materials and a commodity for foreign exchange earnings for many nations.
The exploitation of minerals from the earth, represents one of man’s early areas of civilization.
No nation experiences significant advances in technology and diversification of economy with the associated increases in foreign exchange and creation of jobs for her populace without mining. It is on this premise, that researchers, investors and the government view mining and processing of local coal deposits as a great potential.
The modern Coal Mine
A modern coal mine is a highly mechanized industrial plant that has to meet strict standards of engineering design and operation. The size, power, strength, monitoring and control features, and automation of mining equipment.
The Mining Process
The coal mining process consists of several sequential stages:
(1) Exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks;
(2) Analysis and selection of a mining plan
(3) Securing the markets
(4) Developing the mine
(5) Extracting the coal
(6) Processing the coal if necessary
(7) Decommissioning the mine and releasing the property for post-mining use.
The two essential requirements that must be fulfilled before a prospective coal mine can enter the development stage are confirmation that there are sufficient minable reserves of adequate quality with no unacceptable environmental or permitting risks, and confirmation of an assured or contracted market for a substantial fraction of the coal that will be mined.
Coal seams can be mined by surface or underground methods, with the choice of mining method dictated by both technical and economic factors.
The important technical factors are the thickness of the coal seam, the depth of the coal seam, the inclination of the seam, and the surface topography.
The important economic parameters are the relative costs of mining coal by surface and underground methods including costs associated with any site-specific land use constraints, the cost of removing the material above the coal seam in the surface method, and the price of coal.
The price for any particular coal is related directly to coal quality due to the higher percentage of coal mined in Nigeria. The price for steam coal is dependent primarily on its heating value and sulfur content.
