Coal Mining and Processing The National Academies Press. Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining.
Zith — reaction of coal mining
Coal fires are a natural phenomenon; however, coal mining by humans has assisted the propagation of these fires and thereby enhancing the environmental pollution (Pone et al., 2007). The ignition of coal mine fires is of global concern as it may be attributed to significant environmental problems (Stracher and Taylor, 2004, Avila et al., 2014).

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. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a pit, and ...
Coal Gasification - an overview | ScienceDirect Topics
In Environmental Impacts of Coal Mining & Utilization, 1987. 4.1 Basic Principles. Coal gasification means the complete conversion of coal into gas using heterogeneous gas solid reactions. The main process is the reaction of the carbon of coal with steam, at pressures below 10 MPa and temperatures above 750°C, to form a “synthesis gas” containing mainly CO and H 2 with smaller amounts of ...
Acid mine drainage - Wikipedia
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks ...
Coal mining - Coal preparation | Britannica
Coal mining - Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for ...
CO and CO2 emissions from spontaneous heating of coal ...
Coal mine fires caused by spontaneous heating generally occur by slow oxidation in the coal seams or gob areas and happen most frequently with low-rank coals. Spontaneous heating is a low-temperature coal oxidation reaction which takes place when coal is exposed to air. Coal oxidation is an irreversible exothermic reaction
Types of Coal Mining - FEECO International Inc.
When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the open-pit method, is the ideal technique when ...

Coal, Water and the Environment | WCA
Acid mine drainage (AMD) can be a challenge at coal mining operations. AMD is metal-rich water formed from the stone reaction between water and rocks containing sulphur-bearing minerals. The runoff formed is usually acidic and frequently comes from areas where ore – or coal mining activities - have exposed rocks containing pyrite, a sulphur-bearing mineral.
