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 issues In general, subsurface mining is less environmentally hazardous than surface mining. One problem with subsurface mining is that underground mines sometimes collapse, resulting in the massive sinking of land above the land never quite assumes the appearance it had before mining began. Strip mining also increases land
Auger mining is a surface mining technique used to recover additional coal from a seam loed behind a highwall produced either by stripping or openpit mining.Auger mining is especially employed when contour strip mining has been exhausted and the removal of overburden to access additional coal no longer becomes economically feasible. Live Chat
Open pit mining is also called strip mining because the extraction process destroys vegetation, reduces habitats and pollutes the environment. Mining proponents argue that the process is more efficient, cost effective and safer than shaft mining. Environmental regulations help mitigate damage.

High wall mining accompanied by water pumping and proper mapping can produce large quantities of coal, however the cost of production is also higher compared to other forms of mining.The environmental impact of surface mining is quite extensive that could damage vegetation and water resources leading to controversial projects being stalled.
Feb 27, 2016 · Do a search in Socratic for this question "Is strip mining necessary?" and see if this answer helps with your question. But briefly, strip mining is economically "necessary" to extract some mineral resources, such as coal, when the overburden is not too thick. How does strip mining differ from subsurface mining? Environmental Science Land
The environmental damage caused by surface mining is related to the large amount of surface material that humans remove during mining operations. The environmental effects of surface mining include Habitat destruction Soil erosion Air pollution from dust particulates Pollution (especially from sediments) All surface mining techniques negatively affect the environment, though some methods are
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.

Mar 12, 2017 · Strip Mining: A Destructive Way of Coal Extraction. March 12, Negative effects of surface mining on the environment. A less commonly cited impact of strip mining is that it also causes noise pollution and dust as heavy machinery disrupts topsoil and mining
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 to produce sulfuric acid.
Although both methods have their benefits and drawbacks, underground drilling may just be the cost worthy selection for you Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam (profitable bed of coal) is loed, extracting this black gold can require a
Room and Pillar Mining is Safe, Efficient & Environmentally Friendly. Room and pillar mining is a nonsubsidence plan for a mine, preserving the precious farmland above.It is among the safest and one of the most ecologicallyfriendly approaches to mining coal today, creating a nonsubsidence environment (no movement of land) and maintaining clean water standards.
Jul 01, 2016 · Strip mining impacts. Strip mining is highly destructive. Yet the industry often prefers to strip mine because it takes less labour and yields more coal than underground mining.
