Mining oil shale impacts the environment it can damage the biological land and ecosystems. The thermal heating and combustion generate a lot of material and waste that includes carbon dioxide and greenhouse gas. Many environmentalists are against the production and usage of oil shale because it creates large amounts of greenhouse gasses.
In addition, there have been many coal mining disasters, although work related coal deaths has declined substantially as safety measures have been enacted and underground mining has given up market share to surface mining. [citation needed] Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions.
A German methane detector used for coal mining in the 1960s. Coalbed methane (CBM or coal-bed methane), [1] coalbed gas, or coal seam gas (CSG [1]) is a form of natural gas extracted from coal beds. [2] In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.
Ventilation Air Methane Thermal Oxidizers are used to destroy methane in the exhaust air of underground coal mine shafts. Methane is a greenhouse gas that burns to form carbon dioxide (CO 2) and water vapour. Carbon dioxide is 25 times less potent than methane when emitted into the atmosphere with regards to global warming.
Oil shale mining reduces the original ecosystem diversity with habitats supporting a variety of plants and animals. After mining the land has to be reclaimed, process takes time and cannot necessarily re-establish the original biodiversity. [3] [4] The impact of sub-surface mining on the surroundings will be less than for open pit mines ...
It helps to slow the atmospheric and marine accumulation of greenhouse gases, which is mainly carbon dioxide released by burning fossil fuels. [ 11 ] Carbon sequestration, when applied for climate change mitigation, can either build on enhancing naturally occurring carbon sequestration or use technology for carbon sequestration processes.
The largest and most long-term effect of coal use is the release of carbon dioxide, a greenhouse gas that causes climate change. Coal-fired power plants were the single largest contributor to the growth in global CO 2 emissions in 2018, [ 155 ] 40% of the total fossil fuel emissions, [ 9 ] and more than a quarter of total emissions.
Fugitive gas emissions are emissions of gas (typically natural gas, which contains methane) to atmosphere or groundwater [1] which result from oil and gas or coal mining activity. [2] In 2016, these emissions, when converted to their equivalent impact of carbon dioxide , accounted for 5.8% of all global greenhouse gas emissions .
