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.

Glossary of Mining Terms

Highwall – The unexcavated face of exposed overburden and coal in a surface mine or in a face or bank on the uphill side of a contour mine excavation. Highwall miner – A highwall mining system consists of a remotely controlled continuous miner which extracts coal and conveys it via augers, belt or chain conveyors to the outside.

Geotechnical Aspects of Overburden Materials for Stowing

geology of the coal deposit. Opencast mining is a mining process that generates huge amount of rock waste. Waste rock material generated along with mining is called mine overburden (Prashant et al., 2010). During opencast mining, the overlying soil is removed and the fragmented rock is heaped in the form of overburden dumps (Ghosh, 2002).

Coal Mining, British Coal and The Environment Flashcards

Opencast coal mining takes place from quarries or open pits at the surface. All the overburden is removed and the depth of this overburden is critical to the economics of the mine. The overburden is waste rock and piled up as a spoil heap. Blasting is then used to break the coal up and large machines called drag line excavators are used to extract it.

Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation. The layer under the top soil is known as the "overburden".

Opencast mining for coal as we know it today started in 1942 as a wartime expedient. To boost vitally needed coal output, surface mining became the responsibility of the Mines Department of the Board of Trade and was carried on by the Ministry of Works until 1945, then by the Ministry of Fuel and Power.

IDENTIFICATION OF FAILURE SURFACES IN DRAGLINE DUMPS OF

Draglines are versatile excavating machines deployed to remove overburden in large opencast mines. In India, dragline mining is done to excavate overburden material in strips of 25m to 70m width depending upon the boom length i.e. reach of the machine. Limitation of dumping area within the pit leads to the formation of steep and high dragline dumps.

Opencast Mining (Quarrying): Methods, Advantages

Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.

3 The third stage in the mining cycle, development, is the opening of the ground to access the ore (Hartman and Mutmasky, 2002). Depending on the type of mining method used, the ore can be accessed through sinking a shaft or decline for underground mining, or removing overburden for surface mining.
