Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially ...

However, mine pits may become groundwater sinks, especially in areas such as the Pilbara, where the loss of water by evaporation is greater than the gain through rainfall. If recovery occurs, it may take several years until the groundwater reaches pre-mining groundwater levels, given the climatic conditions in …

Mining Methods • Coal is mined by two main methods - surface or 'opencast' mining and 'underground' mining. • The choice of method is largely determined by the depth, geology of the coal deposit and other factors. • The majority of the world's coal production is coming from Opencast mines. • This scenario is same in India also. 3.

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 ...

OPEN CAST MINING METHOD Open Cast Mining Method • Open cast mining is a surface exploitation method, used mainly for coal. It resembles open pit mining but differs in one unique respect: The overburden is not transported to waste dumps for disposal but cast or hauled directly into adjacent mined-out panels.

Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast mining practices. Phytomining for a range of metals is a real possibility, with the additional potential of the exploitation of ore bodies that it is uneconomic to mine by conventional methods.
