Surface mining is the predominant exploitation method worldwide. In the USA, surface mining contributes about 85% of all minerals exploitation (excluding petroleum and natural gas). Almost all metallic ore (98%) and non-metallic ore (97%), and 61% of the coal is mined using surface methods in the USA (Hartman and Mutmansky, 2002).
surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are too great to commence a surface operation. Once the economic feasibility has been verified, the most appropriate mining methods must be selected according to the
Mar 01, 2010· Zhengao et al. and Mishra et al. distinguished a narrower purpose of the lateral mining method, for low-dipping strata of high thickness. [13,14] In turn, for the surface mining .

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
Surface mining, method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying. See also mining and coal mining. Bisbee: Lavender Pit The Lavender Pit, a former .
mining equipments selection. This system is able to involve the expert knowledge in primary and secondary selection of equipment for surface coal mines [3]. In 1990, another expert system, in order to classify equipment, was planned in the open pit coal mine of .
The selection is based on technical and environmental aspects and surface mining is preferred to extract the minerals from the surface area. As compared to underground mining this method of mining removes soil and rock overlying the mineral deposit.
Placer mining. Placer mining is a way of obtaining mineral and metal resources from loose river sediments. The water helps sift the valuable resources (such as gemstones or gold) from the sand, mud, and gravel in the riverbed. Placer mining occurs on a much smaller scale than other methods of surface mining.

appropriate mining method is selected based on technical, economic, and environmentally accountable considerations. The first step in selecting the most appropriate mining method is to compare the economic efficiency of extraction of the deposit by surface and underground mining methods . This section reviews surface mining methods and ...
-responsible for more than 90% of surface mine production-open pit and open cast mining ranks as the most important surface methods -the term quarry is used in the mineral industry and general literature to mean a mine that produces stone or aggregate (this term does not describe a mining method.
Choosing a mining method. The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.
Nov 02, 2011· In-situ leaching (ISL)/ Solution Mining Solution mining includes both borehole mining, such as the methods used to extract sodium chloride or sulfur, and leaching, either through drillholes or in dumps or heaps on the surface. 2 February 2016 Prof. Dr. H.Z. Harraz Presentation Mining Methods, Surface mining 65 ISL salt mine ISL sulfur mine Hot ...
Conventional Methods of Surface Mining. Open-pit mining and strip mining are the two major categories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction.
the mining technologies currently in use on Federal leases and the potential for commer-cial mining technologies to extract Federal coal reserves from deep underground seams. The chapter discusses: three surface mining techniques that are used in the West: 1) area strip, 2) open pit, and 3) terrace pit; two methods of underground mining in
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...
Jul 31, 2020· Brenda Scott Last Modified Date: July 31, 2020 . Surface mining is a method of mining used to extract minerals and metals which are near the surface of the Earth. There are three basic types of surface mining: open pit mining, strip mining, and quarry mining.These methods are much more economical than underground mining, yet they can have a more significant impact on the surrounding ...
