Samples 16 are from surface water sources (river, stream and spring), while Samples 710 and 1113 are from water boreholes and shallow water well, respectively, both groundwater sources. Sample 1 was collected from the Nyaba river which is relatively far removed from the Okpara Coal Mine (see Fig. 4). Samples 2 and 3 were taken from a stream which flows across the Okpara Coal Mine; however, while

The high visibility of unsightly coalpreparation waste piles, especially in the highly populated East, and the fact that approximately 40 percent of the total land disturbed by past and present mining activities is the result of coal mining operations have caused coal mining companies to become leaders in practicing reclamation concurrently with extraction operations.
Its exports of the metal are valued at about 1 billion annually, and it has the fourthlargest reserves of manganese in the world. That said, the history of manganese in Australia is fairly short.
19/3/2019#0183;#32;Coal continues to be a major source of energy in the US, which is home to multiple mines dedicated to harvesting the mineral despite the rise of many alternative sources of energy. A landmark report recently highlighted that most of the coalfired plants across America are contaminating the surrounding water, adding further fuel to the argument against their use.
Hydrogeochemical assessments were carried out in the vicinity of Okpara coal and Obwetti fireclay mines, Enugu, Nigeria to investigate the hydrogeochemical characteristics and constituents of
This figure is estimated to be about 90 to 95 percent for eastern coal mines, and about 40 to 50 percent for all coal 21 mines. 4. Beneficiation wastes (tailings) associated with some metallic ore and eastern coal mining operations contain significant levels of hazardous materials that can

The sources and sinks of manganese in underground coal mine workings are poorly understood compared to those of iron. The geochemical system in the secondary egress drift of Caphouse Colliery near Horbury, UK, is an ideal system for studying these processes. Five locations along the drift and four secondary inflows to the drift were sampled 24 times through the year commencing May 2005.
