Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore.
acid mine drainage is environmental impacts. to keep from flooding water, it must continually be pumped out. the water has a very low pH, which lowers the pH of nearby soils and streams. it is also a dangerous job. accidental burial, explosions, and fires, inhalation of gases and particles that over a long amount of time can lead to occupational respiratory diseases, including black lung ...
Surface mining is often preferred to subsurface mining by companies in the industry because it is less expensive, there are fewer complications with electricity and water, and it is safer. However, surface mining can be more environmentallydamaging than subsurface mining. Types of Surface Mining OpenPit Mining
Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Oct 10, 2016· Strip mining is done on the surface; underground mining is done below the surface. In strip mining, the ore is extracted from the surface in layers resulting in a deepening artificial valley. This is done when the ore is relatively near the surface. In underground mining, mine shafts are bored or dug from the surface to the underground layers where the ore is located, and ore extraction takes ...
Jun 20, 2019· Subsurface mining is the extraction of minerals and ores from underground. Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and requi...
Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining that involves the topographical alteration and/or removal of a summit, hill, or ridge to access buried coal seams.. The MTR process involves the removal of coal seams by first fully removing the overburden lying atop them, exposing the seams from above.
Environmental Problems of Surface and Underground Mining: a review. ... Additional subsurface mining methods include hard ro ck mining, ... illegal mining, and environmental impact of sand mining ...
subsurface mining is used. Surface mining is done by removing (stripping) surface vegetation, dirt, and if necessary, layers of bedrock in order to reach buried ore deposits. Techniques of surface mining include: openpit mining, quarrying or gathering building materials from an openpit mine, strip mining .

Environmental Impacts Laws Details about how the topsoil will be affected and how it will be replaced must be stated before mining begins. All affected water must be processed and cleaned before leaving the mining site. Procedures for public notice, public participation and
Contour Strip Mining (what is it and environmental impact) Used to mine coal and hilly areas, buldozers cut terraces into the side of a hill and as you find each mineral, the overburden is placed on the terrace underneath it. ... Subsurface Mining Environmental impacts. Has much less of an impact than surface mining, but can cause cave ins ...
What are positive impacts of subsurface mining? Answer. ... Subsurface mining is less disruptive to the environment that strip mining, however the danger to the miners is greater ...
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.
Coal, Strip Mining, and its Environmental Effects Going to a school like Penn State entitles you to many advantages that smaller schools don''t have, such as diversity, world renowned professors, and several different majors to choose from.
