The air in mines can be contaminated by the presence of other gases such as carbon monoxide, hydrogen sulfide, methane, and excess of carbon dioxide. Due to being in a confined space these gases are not always able to disperse and can therefore build up in the mine, and due to their combustible, explosive, or toxic qualities this is a serious issue.
#0183;#32;Methane is a simple gas, a single carbon atom with four arms of hydrogen atoms. Its time in the atmosphere is relatively fleeting compared to other greenhouse gases like CO 2 any given methane
#0183;#32;Owing to the facts that: (1) indigenous microbes have been shown to convert coal to methane, (2) indigenous microbes in coal mines with no gas production history can be energized to produce methane from coal upon nutrient addition, and (3) microbes in mine water generated more methane than those from other microbial sources, such as cow dung, paddy field soil, termites,
Coal Mine Methane (CMM) is a blend of air and Methane released from rock strata as a direct result of mining activities. Methane trapped within a coal seam emerges in a mine after layers of a coal face are removed. Additionally, Methane can seep out of vents from abandoned mines, or appear after a rock collapse from a postmining area.#179;
The methane gas produced by the coal can spontaneously combust which would cause mine fires and possible endanger the lives of the mine workers. The leakage of methane, carbon dioxide, and other types of greenhouse gases from these coal mines is affecting the worlds atmosphere with global warming (Coal, 2010).
Coalbed methane (CBM or coalbed methane), coalbed gas, coal seam gas (CSG), or coalmine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries. The term refers to methane adsorbed into the solid matrix of the coal. It is called ''sweet gas'' because of its lack of
Working Mine Methane emissions from working underground mines make up the majority of emissions from coal mining related is widely found to make the greatest contribution to these emissions, with US EPA figures suggesting that over 50% of all global methane emissions from coal mining arise in this form.
Methane gas that occurs in coal deposits can explode if it concentrates in underground mines. This coalbed methane must be vented out of mines to make mines safer places to work. In 2017, methane emissions from coal mining and abandoned coal mines accounted for about 9% of total methane emissions and nearly 1% of total greenhouse gas emissions (based on global warming potential).
#0183;#32;Owing to the facts that: (1) indigenous microbes have been shown to convert coal to methane, (2) indigenous microbes in coal mines with no gas production history can be energized to produce methane from coal upon nutrient addition, and (3) microbes in mine water generated more methane than those from other microbial sources, such as cow dung, paddy field soil, termites,
#0183;#32;Maximum accumulated methane was cc ( mole methane per gram of coal) on 63rd day and concentration was %. Other researchers reported methane production from coal in the range of about 100 mole methane/g coal ; mmole methane/g coal was produced in experiments of Green et al. .
Mine collapses (or mine subsidences) have the potential to produce major effects above ground, which are especially devastating in developed areas. German underground coalmining (especially in North RhineWestphalia ) has damaged thousands of houses, and the coalmining industries have set aside large sums in funding for future subsidence damages as part of their insurance and statesubsidy
The effects of mining coal on the environment. There are 2 ways to mine coal Strip Mining and Underground Mining both ways have their own impact to the environment and health. We know it but coal is such a cheap energy source that we dont want to let go of it. The negative effects of coal mining cannot be disputed:
