 · For those who are unfamiliar, strip mining is a form of surface mining that focuses on the collection of tar sand and coal, which both rest somewhat close to Earth''s surface. Those who support strip mining point to the increased ease of access and all of its attendant benefits.

Types of Surface Mining | American Mine Services

In particular, surface mining is used to retrieve sand, gravel, stones, coal, iron and other metals. There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted. These include strip mining, open-pit mining, mountaintop removal, dredging and highwall mining.

Strip Mining

Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

What Is Subsurface Mining?

 · 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.

Surface mining

SURFACE MINING. Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.

What is mined in subsurface mining?

 · Subsurface mining consists of digging tunnels or shafts into the earth to reach buried mineral deposits. This form of mining is most commonly used for zinc, lead, nickel, tin, gold, copper, diamonds, phosphate, salt, coal, and uranium.

Mining

 · Strip Mining. When resources are available close to the surface, a strip mine is the most efficient method of extraction. The layers of regolithcovering the resource are taken away, and the exposed ore is mined. This method is also called open-pit mining, or regolith harvesting, depending on the depth of the work.

The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. mining on the basis of the deposit geometry and type.

What are the advantages of strip mining?

 · 5/5 (478 Views . 21 Votes) List of Pros of Strip Mining. It is much more efficient compared to underground mining. Those who advocate for strip mining believe that the recovery rate of materials is higher using the method. It is lower in cost. It is safer than underground mining. It is hazardous to human health. It is harmful to the environment.

What is Strip Mining?

Strip mining is a mineral-extraction 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. As the process suggests, it is a form of surface mining, and it is primarily used to extract ...

 · What is Strip Mining? Surface mining, counting strip mining, mountaintop removal mining and open-pit mining, is a wide classification of mining where soil and rock covering the mineral source (the ''overburden'') are gotten rid of, unlike underground mining (or deep mining) where the overlying rock is kept in place, and the mineral is taken out through shafts or tunnels.
