Mar 25, 2012· Surface mining is safer and easier than subsurface mining. Surface mining does more damage to the environment than subsurface. Surface mining creates more of a mess then subsurface or open cut mining.
Strip mining is sensible when the ore body is near the surface. The practice includes some of the largest machines on earth, removing long strips of overlying soil and rock and then removing coal deposits. Openpit mining utilizes blasting and mineral removing, .
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...

Unformatted text preview: / Points What is a critical difference between surface and subsurface mining? mining is more expensive than subsurface mining mining is above ground; subsurface mining is below ground mining causes less environmental damage than subsurface mining mining creates acid mine drainage; surface mining does not .
Jun 14, 2013· Mining techniques can be divided into two broad categories: surface mining and subsurface mining (See Figure 1). Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities. Conversely, subsurface mining involves sinking a mineshaft and digging tunnels to reach a ...

What is a critical difference between surface and subsurface mining? A) Surface mining is more expensive than subsurface mining B) Surface mining is above ground; subsurface mining is below ground C) Surface mining causes less environmental damage than subsurface mining D) Subsurface mining creates acid mine drainage; surface mining does not
Apr 21, 2014· The Difference Between Underground Mining And Surface Mining 1. The Difference Between Underground Mining And Surface Mining The process of removal of essential mineral ores or geological substances from soil or sand is called mining. These minerals are of great value and are abundantly available in rocks and earth''s surface.
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 ...
Mining activities can be broadly divided in two types 1. Underground mining 2. Surface mining Now let''s talk about surface mining Depending on the topography, nature of the strata, working conditions, depth of the deposit and future use of the lan...
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 require the drilling of vertical or horizontal shafts for access.
Dec 03, 2009· "Strip mining" is the practice of mining a seam of mineral by first removing a long strip of overlying soil and rock (the overburden). It is most commonly used to mine coal or tar sand. Strip mining is only practical when the ore body to be excavated is relatively near the surface.
Nov 19, 2016· There is a lots of difference between surface mining and subsurface mining,here i am starting with the basic definition below: SURFACE MININGWhen the ore or mineral is present on near surface or shallow depth then excavation is carried out on th...
Strip mining: removal of "strips" of soil and rock to expose ore, used when desired ore is relatively close to Earth''s surface. Openpit mining: creation of a large pit or hole in the ground that is visible from Earth''s surface, used when resource is close to the surface but extends beneath the surface both horizontally and vertically.

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.
As the name indicates Mining engineering is related to mines. Blasting the mountains, carving and maintenance of mines and excavation of minerals are all part of mining engineering. Geological engineering is the application of Geological principle...
Surface mining When an ore bed has been located relatively close to Earth''s surface, it can be mined by surface techniques. Surface mining is generally a much preferred approach to mining because it is less expensive and safer than subsurface mining.
