Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Coal has remained the main source of energy in the UK from 1700 to the end of 1970s, and it still plays an important role in the power generation. The paper discusses the current coal consumption in the UK together with environmental impacts of coal mining, coal processing and coal .
Thirty years ago, the introduction of the electronic carbon monoxide alarm became a much more humane early warning system for deadly gasses in coal mines, and the job of the longserving yellow feathered friend of the coal miner became redundant. But the saying, "Like a Canary in a Coal Mine" continues to live on as a conventional metaphor.

Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.
Furthermore, mining and air pollution kill thousands each timely addition to the series, this book critically reviews the role of coal in the 21st century, examining energy needs, usage and health implications.
Surface Mining, Department of the Interior, located in Denver, Colorado. The module is an example of the technical assistance the Federal government furnishes States to assist them in meeting the requirements of the Surface Mining Control and Reclamation Act of 1977, upon which their State surface coalmine regulating programs are based.
The coal industry serves a vital role in the nation''s economy by producing fuel for more than half of its electricity. Despite the industry''s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling 20 billion to 25 billion and net income between 1 billion and 2 ...

Acid Mine Drainage: Chemistry Acid mine drainage impacts stream and river ecosystems through acidity, ferric ion (Fe 3+) precipitation, oxygen depletion, and release of heavy metals associated with coal and metal mining, such as aluminum (Al 3+), zinc (Zn 2+), and manganese (Mn 2+).. When mineral deposits that contain sulfides are mined, they have the potential to produce acid mine drainage.
Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

A thorough understanding of subsistence patterns in a particular region allows the effects of underground mining on the surface to be quantified. The coal mining industry uses a range of engineering techniques to design the layout and dimensions of its underground mine workings so that surface subsidence can be anticipated and controlled.
