Strip mining Britannica

The common strip-mining 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 overburden (if needed), stripping, removal of the coal or other mineral commodity, and reclamation.

Strip Mining, Open-pit Mining, Surface Mining, Mining

Strip mining, like other types of surface mining, finishes in hurting the area around the mine. The rock, gravel, trees, plants, and filth are dumped in regions round the mine. When it rains, this runs over the land and into watercourse and rivers. The rain pushes the mine

Strip Mining an overview ScienceDirect Topics

In contour or area stripping, the overburden is hauled with different equipment than what digs or removes the overburden. In strip mining, the overburden is mined and moved by the same equipment: draglines or continuous excavators. The movement of overburden in strip mining is called the casting process.

Surface Mining Techniques used in the Oil Sands Oil

The strip ratio (SR) is the simplest measure of mining efficiency. Strip ratio is the fraction of overburden (or waste ore) versus the weight of bitumen-rich oil sands. A strip ratio of 2 is considered high but feasible if the ore grade is high enough. A better measure of mining economics is the TV:BIP ratio. TV:BIP is defined as the total mining volume (TV) divided by the volume of bitumen contained

Andrew P. Schissler, in Encyclopedia of Energy, 2004. 2.3 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.

10 Different Types of Mining Operations and Mines

There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.

What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
