Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure Openpit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the ...

Openpit mining WikipediaOpenpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or of types of machine in open pit mining
The two main types of mining are surface mining and underground mining. Mining is further divided into several other egories including room and pillar mining, slope mining, block caving, quarrying, openpit mining and in situ mining.

The three main types of surface coal mining are strip mining, openpit mining, and mountaintop removal (MTR) mining. Surface Mining: Strip Mining Strip mining is used where coal seams are loed very near the surface and can be removed in massive layers, or strips. Overburden is usually removed with explosives and towed away with some of the largest vehicles ever made. Dump trucks .
· The open pit method is sometimes used in coal mining where numerous seams lie parallel to each other and outcrop on relatively flat terrain. Mountaintop Removal Mining Mountaintop removal mining (MTR), often referred to as mountaintop mining/valley fills, is a form of surface mining that involves extreme topographic change to the summit or summit ridge of a mountain.
Surface mining methods can be broadly classified as openpit mining, which includes quarrying, strip mining, contour mining, dredging, and hydraulic mining. Topography and the physical characteristics of the deposit strongly influence the choice of method. In openpit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. This method ...
Openpit mining is a technique commonly used to mine copper. Sand, gravel, clay, granite, and other materials used in building are mined in quarries. This type of mining begins by blasting into rock in a manner to create the greatest fracturing. Rocks are further reduced by crushing machines and separated according to size.

· Openpit mining refers to mining in the open space with mining, loading and transportation equipment according to the occurrence conditions of ore deposits. Some deposits are large in scale, shallowly buried, and even exposed on the surface. For this type of deposit, as long as the overlying rock layer and part of the surrounding rock are stripped off, useful minerals can be directly .
The higher productivity for open pit mining equipment also lowers costs. The necessary underground equipment for maintaining productivity is more expensive on a unit basis capacity than corresponding open pit equipment. Furthermore, the large production scale and share number of open pit mines have provided the opportunity for manufacturing
Mines in Ontario are either open pit or underground, depending on the type of ore and its loion. Open pit mining is generally used for large, lowgrade mineral deposits that are close to the surface while underground mining is generally used for deeper, concentrated deposits5. Open pit mining is used to extract ore deposits that are loed close to the surface, since, on average, the cost ...
The ambient noise level of the underground mining area is affected by the operation of the cutting machines, tub/conveyor movement and blasting of the coal. The movement of coaling machines and transport unitsconveyor, tubs and transfer points caused audible noise which becomes disturbing underground because of the poor absorption by the walls. Noise Pollution due to Mining Activities ...
