Refined coal Wikipedia

Refined coal Wikipedia

Refined coal is the product of the coalupgrading technology that removes moisture and certain pollutants from lowerrank coals such as subbituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically precombustion treatments and processes that alter the characteristics of coal before it is burned.

Mine development. Coal can be extracted from the earth either by surface mining or underground mining. In openpit coal mining, a pit is dug in an area and this pit becomes the openpit mine, sometimes called a mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting becomes too great.

Coal slurry (also known as sludge) is the toxic solid/liquid byproduct of the mining and processing of coal. Strip mines (see: strip mining) and mountaintop removal (see: mountaintop removal) generate enormous quantities of "overburden" (rocks and soil), which is then used to create dams, usually in valleys or hollows between two mountains.

Coal Mining. Print. Coal is a solid that, if we are to use it, must be extracted from the earth. This is coal mining, going into the earth to remove coal for our consumption. The basic steps of mining and processing coal are described below. There are two general methods of coal mining: surface mining and underground mining.

Coal exploration activities to discover coal reserves include creating a geological map of the area, carrying out geochemical and geophysical surveys and exploration drilling. The mining operation only begins if the coal can be economically recovered. As per the BP statistical review, the world coal reserves are estimated to be 1035 × 10 9 t (1035 billion tonnes) [2].

Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

Coal in the seam is then excavated. Surveyors are present to ensure the coal is mined optimally. The coal is blasted into smaller layers, which are dug up and transported by trucks to a processing plant. Throughout the coal mining process, we minimise the impacts on the environment including the air and water quality, noise and heritage sites.
