Most mining activities in Nigeria are open cast mining which has a highly damaging effect on the environment. Some of these environmental effects include loss of prime agricultural land, forest cover, water regime, air quality and biodiversity. Mining of solid minerals like coal has the potential of causing environmental degradation.
Coal mine gas (firedamp) is a problematic phenomenon associated with coal mining, as the gas can form explosive mixtures together with air. The main component of the primary coal seam gas is methane in a concentration of 90-95 the gas develops during the geochemical conversion of organic substances to coal (carbonisation).
Apr 01, 2018 The estimated reserves of these coal mines are 2.1Gt, i.e. about 84 of the total estimated reserves of the 2.5 Gt of coal. The coal mines are open cast (surface mining) and underground . An overview of the mines is presented in Table 1.

Open pit mining - also called open cut mining or open cast mining - is a surface mining technique used to extract rocks and minerals. It requires large-scale equipment, including shovels and drills. Motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines.

Jan 15, 2004 In the present work, the background gamma terrestrial radiation levels 1 m above the ground on the surfaces of Okpara underground and Okaba open cast mines and in the mine tunnel at the Okpara mine are measured. Okpara is sited at Enugu, Enugu State, Nigeria, while Okaba is located at Okaba, Benue State, Nigeria.
Jan 01, 2004 Thus, the outdoor gamma dose rates appear to be generally lower at the Okaba open cast mine than at Okpara. The indoor dose rate values range from 11.0 to 17.0 nGy h(-1) in both environments. These indoor measurements have nearly the same mean values 14.4 and 14.5 nGy h(-1) for Okpara and Okaba environments, respectively.
Coal is mined using two techniques surface mining which is sometimes referred to as open cast mining, and underground or deep mining. The most appropriate mining technique is largely determined by the geology of the coal deposit. Once raw coal is mined, it is often crushed, sized and washed in processing plants where the product consistency.
