24/08/2014· Coal mining seriously jeopardizes the ecological environment of the mining area, with the potential to cause a variety of impacts including surface subsidence, land desertification, soil degradation, surface and groundwater pollution, vegetation destruction, ecosystem degradation, undermined biodiversity, landscape damage and crop failures (Fan et al. 2003).

Effects of Coal Mining on Environment - Term Paper

What are the effects of coal mining on the environment? The coal industry has given rise to many environmental issues such as adverse effects on the air, land and water quality of the surrounding areas of the mines and continues to affect global environment as a whole.

01/01/2017· A modelling experiment examines changes in rupture potential in stiff roof units for each stratigraphic type as discrete unit thickness and location are manipulated through a range of values. Results suggest that the stiff-to-compliant ratio of the host rock has an impact on the relative stress-inducing effects of discrete stiff members. In other words, it is necessary to consider both the ...

How Coal Affects Water Quality: State of the Science ...

20/03/2013· Despite the fact that the global coal trade moves somewhere in the range of a billion tons of coal on the oceans each year, there has been very little research into the effects of coal and coal dust on waterways and the ecosystems they support. As the Northwest considers adding as much as 140 million tons of coal export capacity on rivers and coasts that are home to sensitive and endangered ...

The Effect of Ventilation on Spontaneous Heating of Coal

Spontaneous heating has long been a problem in the mining, storage, and transport of coal. Spontaneous heating is a low temperature coal oxidation reaction which takes place when coal is exposed to air. If the heat produced by the coal oxidation is not adequately dissipated by conduction or convection, it results in a net temperature increase in the coal mass. Because coal oxidation is an ...
