6. Compare and contrast surface and subsurface mining in terms of environmental impact. Level Moderate Answer Surface mining removes large amounts of overburden in the form of soil and rock, along with any living organisms. This material, called tailings, is discarded and can cause significant damage. Depending on the type of resource being sought, a large amount of
Strip Mining. Strip mining gets its name from the fact that the process involves stripping the surface away from the mineral thats being excavated (usually coal). Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators. This type of mining makes sense when the mineral is near the surface.

THE. ENVIRONMENTAL. EFFECTS OF. STRIP MINING A ll mining operations have a disruptive effect on the environment, but the sheer volume of material involved in strip mining makes the impact on the environment especially acute. Surface mining (another name for strip mining) can severely erode the soil or reduce its fertility pollute waters or drain
Jul 06, 2021 Before understanding subsurface mining environmental impacts, you must have information about the subsurface mining definition. Surface mining is the process of extracting minerals from the surface of the earth and some of the most common types of surface mining are pit mining, quarrying, and strip mining. This is the subsurface mining definition.
Oct 23, 2013 Advantages and Disadvantages. Advantages Safer than surface mining, faster than 60% of other mining in the U.S, less disruptive to the environment, leads to more minerals. Disadvantages Costs more, harder to do than surface mining, takes a lot of time.
Feb 25, 2015 The Cons of Strip Mining. 1. Bad For The Environment Strip mining can have unwanted effects on the natural ecosystem of the area where the mining is taking place. Plant and animal life is often killed off, taking years to regenerate.
Mar 23, 2021 Strip mining Strip mining is mining a linear theme by first removing a long strip of overlying soil and rock. The overburden. It is famous for mining coal, lignite, and brown coal. Strip mining is only practical when the miners excavate the ore body relatively near the surface. There are two forms of strip mining, area stripping, and contour stripping.
The benefits and drawbacks of underground mining are Few environmental impacts Minimal surface disruption Mining unaffected by adverse weather Low productivity Higher cost and energy requirements Dangers of radiation and toxic gases Accidents like tunnel cave-ins Higher injury potential Underground tunnels cause surface subsidence
Overall, the process of ISL mining of uranium has considerably less environmental impact than other conventional mining techniques. Both sites, which are remote from urban areas and occur in semi-arid pastoral country, have relatively small surface footprints, are environmentally conscious and have initiated some worlds best practice techniques.
Apr 07, 2017 Strip mining and subsurface mining Strip mining (or surface mining) is performed when surface soil and rock are stripped off to reach the mineral of concern. When such operations are done, surface water bodies (lakes, streams, etc) gets acidity. Acid mine drainage occurs when water molecules infiltrates the spoil banks. The water reacts with sulfide minerals
III. Mining Methods and their Impacts A. Strip mining removes surface layers of soil and rock. 1. When a resource sits in shallow horizontal deposits near the surface, the most effective mining method is often strip mining, whereby layers of surface soil and rock are removed from large areas to expose the resource. 2.
The waste, filth, and rock that they take off of the top of the next strip is put on top of the last one. This is recurring until the last strip is done and the waste from the primary strip is brought back to fill it. Strip mining, like other types of surface mining, finishes in
Subsurface Mining Type Brief Description Environmental Impact Underground Coal Underground soft rock mining is a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary (soft) rocks.
May 27, 2020 Mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world.. However, many mining techniques still in use can have serious impacts on both the mining site itself and the
The major partial mining method are strip pillar mining, Wongawilli strip pillar mining, room and pillar mining, and thickness-limited extraction. 1. Strip pillar mining. Strip mining technology is an effective measure to reduce the overburden strata and surface movement and deformation, and it is also one of the important measures in the system of Green Mining.
2020-6-3 Underground mining Sub-surface mining (underground mining) is the way to go when the open pit mining operation becomes far too expensive. Mining companies decide whether or not to mine underground depending on the strip ratio of the land. If the ratio is too large, surface mining is too costly and sub-surface mining is the way to go.
Open Pit Mining. Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft).
Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to
The two ways we learned about in class were strip mining and underground mining (2/13/02). Strip mining is the coal mining procedure that I found most interesting. Strip mining, for example, has the highest productivity out of all the ways to mine coal it extracts thirty to forty tons of coal per worker per day (2/13/02). Also,...
How does strip mining impact the environment? Strip mining destroys landscapes, forests and wildlife habitats at the site of the mine when trees, plants, and topsoil are cleared from the mining area. This in turn leads to soil erosion and destruction of agricultural land.
