In today's technologically-advanced society, mining techniques are always improving. For example, using surface mining techniques, many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers.

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.

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.

Mining Corp. is the world's largest producer of electric mining shovels and a leading producer of surface mining equipment including blasthole drills, walking draglines and wheel loaders. We offer solutions worldwide for use in the mining and processing of essential minerals.

Equipment Selection for Surface Mining: A Review. 2013-7-19 productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit.

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.

Whether you need to excavate, transport or process ore, rock or overburden more efficiently, our comprehensive range of cutting-edge surface and underground mining equipment is designed to increase your productivity and boost your bottom line.

SURFACE MINING METHODS AND EQUIPMENT

Jan 03, 2020· While the majority of this post will focus on surface mining equipment, it's essential to explain the differences between the two main mining types. Above ground, or surface mining, includes strip mining, open-pit mining, and mountaintop removal mining. Essentially, surface mining is the term used to describe any mining where the rock ...

Classifying the equipment selection process into three phase's: type of fleet, size of equipment and calculation of required numbers, the present article focuses on different application methods in each of these phases, their advantages and shortcomings.

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.

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.
