Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
The interior of SubTropolis. SubTropolis is a business complex located inside of a 55,000,000-square-foot (5,100,000 m 2), 1,260-acre (5.1 km 2) mine in the bluffs north of the Missouri River in Kansas City, Missouri, United States.
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.
The Cannington Silver and Lead Mine is an Australian underground mine located in north-west Queensland, in the Shire of McKinlay, about 200 kilometres (124 mi) southeast of Mount Isa. The deposit was discovered by BHP in 1990. [1] The mine was the supplier of silver for the Sydney 2000 Summer Olympics and the Beijing 2008 Summer Olympics. [2]
Geological sequestration refers to the storage of CO 2 underground in depleted oil and gas reservoirs, saline formations, or deep, coal beds unsuitable for mining. [106] Once CO 2 is captured from a point source, such as a cement factory, [107] it can be compressed to ≈100 bar into a supercritical fluid.
This is an accepted version of this page This is the latest accepted revision, reviewed on 24 January 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Underground product gas is an alternative to natural gas and potentially offers cost savings by eliminating mining, transport, and solid waste. The expected cost savings could increase given higher coal prices driven by emissions trading , taxes, and other emissions reduction policies, e.g. the Australian Government's proposed Carbon Pollution ...
