    The Social and Environmental Consequences of Coal Mining

    Mining produces large mountains of solid waste. Coal heaps are prone to spontaneous combustion. Leachate from waste heaps are often acidic, adding to the general and large scale acid mine drainage impact and interferes with underground and surface water. Mining also has serious social consequences: on the movement of people, on people’s health and the environments they live in. Page 4 of 24

Previous research has shown that is it possible to use some wastes to produce concrete blocks (Leenders, 1984; Hood, 2006; Pagnussat, 2004; Vargas, 2002). Thus, the aim of this work was to study the use of coal waste to produce concrete blocks for

    Environment Impact Assessment of Coal Mining

    Coal mining has significant impact on land and land use, some of the land related impact are: Loss of biodiversity, Economic loss or loss of livelihood due to displacement and encroachment of agricultural land and Impact on water resource (in term of water availability and quality). Open cast mine has significant impact on land as compared to underground mine. 1) Land Around 4 ha of land is

    How Anthracite Coal Production Affected the Great

    Waste coal consists of low-energy discards from the coal mining industry (Ewall, 2007). It is referred to as “culm” in the Eastern Pennsylvania anthracite region and “gob” or “boney” in the bituminous coal mining regions, like Western Pennsylvania and West Virginia (Ewall, 2007). Waste coal is usually accumulated to appear as hills

    THE DIRTY FACTS ABOUT COAL

    MINING Large tracts of forest and other productive lands are often cleared and communities are displaced for coal lead and mercury. Coal combustion waste may be stored in waste ponds or landfills, which are often unlined. Contaminants may leach into ground and surface water that people depend on for drinking. This can increase rates of cancer, birth defects, reproductive problems and

    THE IMPACT OF DISPOSAL AND TREATMENT OF COAL MINING WASTES

    Coal mining wastes is traditionally dumped as a cone-shaped tip in China, which will pollute air, soil and water environment and landscape by dust, leachate, self-ignition and no vegetable cover. Since 1980s, the technique for coal mining wastes disposal has been changing into transporting them directly to fill subsided land for reuse of subsidence land. And now coal mining wastes dump and
