Surface mining Opencast mining, otherwise known as surface mining consist of three different techniques: strip mining, open-pit mining, and mountain top blasting. In general, the three processes include breaking up soil and rocks via explosives and then removing debris until coal seams are exposed.

What Is Subsurface Mining? | Reference.com

Subsurface mining: Commonly used for zinc, lead, nickel, tin, gold, copper, diamonds, phosphate, salt, coal and uranium. Is used when the resources occurs in concentrated pockets deep underground. The most dangerous form of mining, consists on deep excavation. Networks of tunnels are dug or blasted out to follow deposits of the mineral, removed by the miners. Subsurface mining can be mind ...

mining process of copper surface or subsurface

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.

Mining | About Environment

Mining techniques can be divided into two broad categories: surface mining and subsurface mining (See Figure 1). Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities.

subsurface mining by jose saade on Prezi

In surface mining, the ore is accessed directly from the Earth's surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface.

Many surface and subsurface exploratory projects are undertaken with the aim of locating: a) oil and gas accumulations and coal beds b) concentrations of commercially important metallic minerals (ores of iron, copper, and uranium)

Modern Mining - How Eagle Mine produces nickel and copper

Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and require the drilling of vertical or horizontal shafts for access.

Sub-Surface Mining on emaze

Surface mining When an ore bed has been located relatively close to Earth's surface, it can be mined by surface techniques. Surface mining is generally a much preferred approach to mining because it is less expensive and safer than subsurface mining.

Ecological effects of subsurface mining Surface mining techniques don't work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines produce

Surface and Subsurface Methods of Mineral Exploration

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.

Mining Facts for Kids - Kiddle

Subsurface mining removes coal and various metal ores that are too deep to be extracted by surface mining. It does not disturb the land as much as surface mining, produces less waste material, but leaves much of the resource in the ground and is more dangerous and expensive.
