There are several types of problems in coal mining.These include safety, faults, the water table, washout, thin seams, and split seams. Significant mining engineering and other industrial engineering goes into helping coal mining operations to deal with these challenges.
In a particularly spectacular case in the German Saar region (another historical coal-mining area), a suspected mine collapse in 2008 created an earthquake measuring 4.0 on the Richter magnitude scale, causing some damage to houses. Previously, smaller earthquakes had become increasingly common and coal mining was temporarily suspended in the area.
The damage caused by mountaintop removal strip mining has had a calculable effect on the environment and communities in Appalachia. The resource rich region remains economically deprived and suffers from the externalities of coal mining, including the health problems caused by coal pollution. [12]
The collapse of an 11-story coal mining plant in Martin County left two workers trapped under the rubble as crews worked to free them Wednesday. One of the workers has since been confirmed dead.
For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. [1] The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverized coal is a significant dust explosion hazard, as large quantities are suspended in air ...
The mine produced 56,768 ounces of gold in the third-quarter of last year, and is SSR's second-largest producing gold mine, operating since 2010. SSR Mining says eight employees detained after ...
Black lung disease (BLD), also known as coal workers' pneumoconiosis, [1] or simply black lung, is an occupational type of pneumoconiosis caused by long-term inhalation and deposition of coal dust in the lungs and the consequent lung tissue's reaction to its presence. [2]
In northern Peru, the World Bank's business-lending arm is part owner of the Yanacocha gold mine, accused by impoverished farming communities of despoiling their land in pursuit of the precious ore. The bank and IFC have stepped up investments in projects deemed to have a high risk of serious and environment damage, including oil pipelines, mines and even coal-fired power plants, an ...
