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 […]

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.
Mining is merely defined as digging in the ground to find something of use. The process has been a part of life since antiquity, and is still the backbone of the world's commerce and production. Mining could be classified in two forms: mining at the earth's surface (surface mining) and mining underground (subsurface mining).
Mar 08, 2018· These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is …
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 ...
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.
What is the difference between surface and subsurface mining . Subsurface mining is used where the material is in veins deep beneath the surface, or obstructed (by rock layers, water tables, or other strata) in a way that make surface access impractical. Read More >>
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.
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 …

The Actual Difference Between Surface and Underground Mining. This historical event highlights the difference between two techniques of mining which are used even today surface and subsurface mining. Types of Methods. Surface mining can be accomplished by the following main methods: Openpit Mining: Removing ore to leave a crater.

Nov 20, 2016· There is a lots of difference between surface mining and subsurface mining,here i am starting with the basic definition below:- SURFACE MINING-When the ore or mineral is present on near surface or shallow depth then excavation is carried out on th...
In surface mining, the ore is accessed directly from the Earth's surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface.

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.
Dec 03, 2009· Best Answer: "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.
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.
