With strip mining, tunnels no longer need to be dug and supported. The lifting of minerals is not done on long routes just to get to the surface either. That said, retrieval and transport are more convenient using surface mining techniques. 2. It costs lower.
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;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
Mining techniques can be divided into two common excavation types: surface mining (above ground) and subsurface (underground) mining. sometimes subsurface mining is also called deep mining
#0183;#32;This technique is also referred to as open cast, open cut, or stripping. Strip mining is done layers where the mining operations go slighter deeper with each pass. In this technique, the first step is the removal of trees, shrubs, and structures on the area to be mined, a process which is usually accomplished with heavy duty bulldozers.
Quarrying is a type of mining and is also called as open pit mining or strip mining. When minerals are found profound beneath the surface, a deep mine has to be dug to dig out them. Quarries are normally dug deeper and bigger; awaiting the mineral resource is worn out.

#0183;#32;Other surface techniques include quarrying and strip mining. Subsurface mining can be done in many ways with a vast number of terms to describe each type. However all types involve digging tunnels or shafts to access a resource that is too far below the surface or too spread out to use a surface technique and remain economical.
#0183;#32;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. The shafts are reinforced with supports before workers access the tunnels.
Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are: Room and Pillar Mining: Removing ore, while leaving behind some for roof support.
#0183;#32;Mining is broadly categorized into two types: surface and subsurface. Surface Mining: Removes materials close to Earth''s surface. Leaves behind spoil banks Area can be reclaimed 5 types Open Pit: Removes materials from an open pit. Used when tunnels may not be stable or overburden is very thin. Strip Mining: Uses shallow pits for removing

Strip mining is a mineralextraction process in which a layer or seam of undesired material (called overburden) is removed from the surface of an area to allow efficient access to a desired material existing underneath the layer being stripped.
#0183;#32;Strip mining is a term used for shallow but extensive open pit mining. Things like coal, bauxite, and oil sands are mined this way. If you are in a strip mine you can see the sky. Underground mining is exactly that underground, using tunnels and/or shafts. High value minerals like gold, copper, uranium, and diamonds are mined in 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 openpit mining.
Strip mining Britannica. Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.. The common stripmining techniques are classified as area mining or contour mining on
#0183;#32;Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.. The common stripmining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of
