Mining - Mining - Surface mining: It has been estimated that more than two-thirds of the world's yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.

Advantages of surface mining include economic and financial benefits for miners and communities and a safer alternative to pit mining, but its disadvantages include environmental impacts, such as erosion and contamination.

Apr 27, 2015· Underground mining is often utilized by mining firms to extract more ore and minerals. Higher production volume mitigates the costs spent on initiating the very expensive method of underground mining. This is how underground mining becomes a cost-efficient strategy.

Open pit mining -- or strip mining -- is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient.

What Are the Benefits of Mining? Despite the ecological harm that mining inflicts we continue to extract substances from the ground because we feel — as a society — that the benefits of mining outweigh the hurts, especially as we develop new ways to counteract the negative impact of mining on the environment. First of all, mining creates ...

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.

The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground ...
