Surface mining techniques don't work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground [.]
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.
Sep 19, 2015· Surface mining does more damage to the environment than subsurface. Surface mining creates more of a mess then subsurface or open cut mining. ... The difference between surface run-off and ...
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

Surface mining, including strip mining, open-pit 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.. Surface mining began in the mid-sixteenth century [dubious ...

Strip Mining. Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining.
Strip mining: removal of "strips" of soil and rock to expose ore, used when desired ore is relatively close to Earth's surface. Open-pit 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.

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...
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...
a) The difference between surface and subsurface mining is that surface mining is on the Earth's surface and moves the un-needed materials out of the way in order to obtain the desired minerals and energy. Subsurface mining doesn't remove the un-needed soils or rock out of the way instead it uses big machines to dig deep underground into ...
Sep 19, 2010· 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.

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.
Distinguish between surface and subsurface mining, between open-pit and strip mines, between shaft and slope mines. Surface mining is the extraction of mineral and energy resources near Earth's surface by first removing the soil, subsoil, and over-lying rock strata. Subsurface mining is the extraction of mineral and energy resources from deep ...
Sep 30, 2011· Surface mining does more damage to the environment than subsurface. Surface mining creates more of a mess then subsurface or open cut mining. ... The difference between surface run-off and ...
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.
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 ...
Feb 23, 2018· As mining progressed, the ore deposits began running out, making it necessary to seek them deeper inside the ground. This historical event highlights the difference between two techniques of mining which are used even today - surface and subsurface mining. Let us .
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...
