Mining Mining Surface mining: It has been estimated that more than twothirds 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 openpit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.

Openpit Mining Operations. Openpit mines are dug on benches that are between four and sixtymeters in size, depending on the size of machinery used to excavate. The walls of most openpit mines are dug at an angle and include steps to prevent avalanches from occurring inside the build site.

The objectives of this handbook are: to protect workers in smallscale surface (openpit) mines from safety and health hazards and risks in their work; to prevent or reduce the incidence and severity of illness and injury in smallscale surface mines, and to promote training, knowledge sharing and social dialogue. The handbook is targeted at all involved in openpit smallscale mining and sets

As a rule of thumb, open pit mining can process ore for 10 per tonne and, where the ore grade is more than double that at 20 per tonne, results would be economic. Consider that 1% of a metric

Openpit 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 openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit

open pits continuously increase. Small changes in the overall pit slope angle have large consequences on the overall economy of the mining operation. A case in particular is the Aitik open pit mine in northern Sweden, which currently faces the design of the overall slope angles for continued mining toward a depth of around 500 meters.
