These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method in North America.(PDF) SURFACE MINING METHODS AND EQUIPMENT ,Academia.edu is a platform for academics to share research papers.
Mar 13, 2011· The selection of mining equipment is a function of the mine plan. Some of the factors considered in the selection of mine equipment include the topography of the pit and surrounding area, the amount of ore to be mined, the speed and distance the ore must be transported for processing and the estimated mine life, among others.Selection Of Surface Mining Method bredepitt.it,A Brief Introduction to the Types of Surface Mining Dredging is a method of obtaining mineral deposits from the bottom of rivers, oceans, harbors, and stre Address: No. 169 Scientific Avenue, National High-Tech Industrial Development Zone, Zhengzhou

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.
Surface Mining Methods After a mineral deposit has been discovered, delineated, and evaluated, the most appropriate mining method is selected based on technical, economic, and environmentally accountable considerations.Methods for Equipments Selection in Surface Mining; review,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 Britain with the help of fuzzy logic.
The mining method selection problem is an approach to equipment selection that is based on the premise that the environmental conditions dictate the mining method used, and that the selection of truck and loader types follows intuitively from the adopted mining method.Selection Of Surface Mining Method bredepitt.it,A Brief Introduction to the Types of Surface Mining Dredging is a method of obtaining mineral deposits from the bottom of rivers, oceans, harbors, and stre Address: No. 169 Scientific Avenue, National High-Tech Industrial Development Zone, Zhengzhou

The strength of the ore and the surrounding rock is one of the most significant geotechnical factors in mining method selection. The strength and related stability of the rockmasses are important for all types of excavation, and are assessed using rockmass classification systems throughout a mine.Methods for Equipments Selection in Surface Mining; review,mining equipments selection.

Sep 20, 2014· The broad objective of this research was to improve current surface mining practices and reduce negative environmental impact of overburden removal in West Virginia (WV). The specific objectives were to (i) compare conventional surface mining method (drilling, blasting, digging, and loading) to a surface miner (SM) method, and (ii) apply the analytical hierarchy process (AHP) to Equipment Selection for Surface Mining: A Review,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, including strip mining, open-pit 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.. Surface mining began in the mid-16th century [dubiousWhat Is Surface Mining? Convergence Training,These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.
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.12.

The selection is based on technical and environmental aspects and surface mining is preferred to extract the minerals from the surface area.

Within the scope of both the ESP and related problems, we outline modeling and solution
-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 methodUnderground Mining Methods — New Pacific Metals,Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.

Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.
In all methods of surface mining, first, the overburden is stripped off using earthmovers.Then, bucket-wheel excavators remove the ore, which is loaded into haul trucks with shovel loaders. When the deposit is exhausted, the overburden is refilled in the crater, and the land is restored with the local vegetation.12.

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 ini) Mechanical excavation methods; such as Open-pit and,3 Surface mining: Is a type of mining in which soil and rock overlying the mineral deposit (the overburden) are removed. Surface mining is the predominant exploitation method worldwide. Surface mining requires large capital investment (primarily expensive transportation equipment), but generally results in: High productivity (i.e., high output rate of ore)
Under similar conditions, surface mining is generally regarded to be more advantageous than underground mining. In the selection between surface and underground exploitation methods, there are a number of most significant factors must be briefly,
