  • Open-Pit Mining Methods

    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. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit

It has been a part of life since antiquity and it is still the backbone of the world’s commerce and production. Well, if it isn’t broken!There are two basic classes of mining: mining at the Earth’s surface and mining underground. This article will concentrate on the former. Surface mining accounts for two thirds of the world’s solid minerals, and is predominantly used in obtaining sand, gravel, crushed.
