    Environmental Risks of Mining

    Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.

    Underground Mining for Meeting Environmental Concerns A

    Underground mining can be considered to be more acceptable than surface mining from environmental and social perspectives since, it often has a smaller footprint than an open-pit of comparable capacity. The main advantage of underground mining compared to surface mining is that in general only the ore is extracted and waste rock is left behind.

    Dangers in Underground Mining - How Underground Mining

    The environmental toll of underground mining is significant. It includes air pollution, changes in water-flow patterns, chemical and gas seepage into water supplies and soil, inaccessible fires in abandoned mines, and dramatic changes in land composition that can make the area unusable after the mining operation is done [source: Saxena]. Then there is the human toll.

    Large stripping machines with excavating wheels used in surface coal mining are employed in other types of open-pit mines. Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steam-driven pumps could be used to remove water from the deep mines of the day.

    Gold Mining and Processing -- The High Cost of Gold

    Gold mining today is different than that in a couple of ways. First, open-pit gold mines are common now, where the "overburden"—the grass and trees and every other living thing above the place to be mined—is removed and the ore is blasted and scooped out. Not only do open-pit mines scar the landscape, they produce 8 to 10 times more waste

    Coal Mining - The Environmental Literacy Council

    Surface mining—including open pit or strip mining—is less dangerous than underground mining, but has a greater impact on surface landscapes. Surface mining requires the removal of massive amounts of top soil (or overburden) in order to gain access to the coal seams, which can cause erosion, loss of habitat, and dust pollution.
