Function Of Coal Mine

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.

8 Methods For Protecting Coal Miners

Coal Mine Dust. The miners should be informed annually about the hazard of dust exposure, and they should be trained in the use and care of the respirators. In addition, the program should be periodically reviewed, and if necessary, corrective action should be taken to maintain program effectiveness.

Coal - Wikipedia

Coal is a fossil fuel that forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite. This involves biological and geological processes. The geological processes take place over millions of years.

13 Pros and Cons of Coal Energy –

1. The mining of coal destroys natural habitats. To remove coal from the ground, various mining processes are used that destroy the natural habitat in that region. Part of that destruction involves the potential pollution of groundwater tables and the removal of trees. There is also the added danger of having a fire begin in a coal mine.


FUNDAMENTALS OF COAL MINE ROOF SUPPORT By Christopher Mark, Ph.D.,1 and Thomas M. Barczak2 ABSTRACT Roof supports can only be understood in conjunction with the rock structure that they support. The strength of the rock depends on geology, and the loads are applied primarily by the in situ and mining-induced stresses.

History of coal mining - Wikipedia

The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today. Compared to stone fuels, coal yields a higher amount of energy per mass and can often be obtained …

Handbook for Methane Control in Mining

Other coal mine chapters deal with methane emission forecasting and predicting the excess gas from troublesome geologic features like faults. Additional coal chapters contain methane controls for shaft sinking and shaft filling, for surface highwall mines, and for coal storage silos. Major coal mine explosion disasters have always involved the combustion of coal dust,

Coalworkers pneumoconiosis - Wikipedia

Coal workers pneumoconiosis, also known as black lung disease or black lung, is caused by long-term exposure to coal dust. It is common in coal miners and others who work with coal. It is similar to both silicosis from inhaling silica dust and asbestos dust. Inhaled coal dust progressively builds up in the lungs and leads to inflammation, fibrosis, and in worse cases, necrosis. Coal workers pneumoconiosis, …

Sentinel species - Wikipedia

Well into the 20th century, coal miners brought canaries into coal mines as an early-warning signal for toxic gases, primarily carbon monoxide. The birds, being more sensitive, would become sick before the miners, who would then have a chance to escape or put on protective respirators .

Coal and Water Pollution | Union of Concerned Scientists

Dec 06, 2017 · All coal plants rely on water. They function by heating water to create steam, which then turns turbines, generating electricity. But the water must come from somewhere—typically a nearby river or lake. “ Once-through ” coal plants pump the water directly from a water source, heat it up, then discharge it back.

Coal mining and chronic obstructive pulmonary disease: a ...

May 01, 1998 · The potential of coal mine dust to cause disabling pneumoconiosis has long been recognised, but research now suggests that pneumoconiosis is not the only respiratory hazard of coal mining. Over the last 30 years evidence has accumulated that miners also experience an excess of chronic obstructive pulmonary disease (COPD), and this has led the British Government to classify …
