In Nigerian coal is mainly used for the generation of electricity that the country needs. The coal mines are predominantly safe with minimal pollution concerns. As a way to discourage community agitation, environmental impact assessment is usually carried out before coal extraction is done. 2.0 NIGERIAN COAL MINE INDUSTRY

coal mining has been successfully carried out using conventional underground mining methods as well as long or all mining methods. Although, coal mining activity ceased in the Enugu for some times now,the current policy of the government to commercialize the coal mining industry is expected to bring a boom in the sector.

Coal mining is the process of extracting coal minerals from under the ground. In this process, the overlying soil layer with existing vegetation is removed and deposited in another fresh area. Thus, the deposition of million tons of overburden in the form of rocks, shale and coarse tailing results in barren, biologically inert overburden dumps

Nigeria's former Ministry of Mines and Steel Development has identified three potential methods of bitumen extraction in Nigeria: (1) small-scale surface mining (2) large-scale surface mining and (3) in-situ extraction (see Figure 2). The depth of bitumen below the surface determines which extraction type is possible. Both in-situ and large-
