What is underground mining. When the minerals are found in rich veins but in large volumes of sterile rocks, the only way to mine them is the underground mining method. These consist of opening galleries, tunnels, and other forms of mining art that allow us to take advantage in an orderly manner of the veins in their threedimensional development.
#0183;#32;Mining is conducted basically in two ways, either underground, or surface mining. Surface mines, or strip mines, are large pits where dirt and rock are removed to expose the minerals. 2. Underground mines are large tunnels that are dug deep into the ground to reach minerals that are too far underground to be reached from surface mines. Surface mining can be done on mountain tops or on
Under similar conditions, surface mining is generally regarded to be more advantageous than underground mining. In the selection between surface and underground exploitation methods, there are a number of most significant factors must be briefly
Surface mining, including strip mining, openpit 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.

#0183;#32;Both opencut and underground mining is used in modern mining. The approaches are different, and there are advantages to each. Opencut mining. Opencut mining gets its name because thats exactly what this type of mining looks like, a big open pit. This type of mining allows for the extraction of minerals that arent very far under the surface.
Mining Operations. Data obtained from the Mine Safety and Health Administration (MSHA) indicated a total of 925 underground (%) and 13,982 surface (%) mining operations. Employees. A total of 59,922 employees, or 62,565 fulltime equivalent (FTE) employees, were reported to MSHA as working at underground mining locations in 2008.
Surface mining, method of extracting minerals near the surface of the Earth. The three most common types of surface mining are openpit mining, strip mining, and quarrying. See also mining and coal

#0183;#32;Strip mining is done on the surface; underground mining is done below the surface. In strip mining, the ore is extracted from the surface in layers resulting in a deepening artificial valley. This is done when the ore is relatively near the surface. In underground mining, mine shafts are bored or dug from the surface to the underground layers where the ore is located, and ore extraction takes
#0183;#32;Surface mining, also called strip mining, delivers economically vital supplies of coal, which powers transportation and creates consumer products, boosting local economies. This type of mining occurs primarily on mountaintops, and dates back to the early 20th century when new machines made moving earth easier.
Surface mining is commonly used to extract coal and copper, and increasingly, precious metals like gold. Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart.
