Opencast Mining an overview ScienceDirect Topics

S.K. Chaulya, G.M. Prasad, in Sensing and Monitoring Technologies for Mines and Hazardous Areas, 2016 Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also

The Environmental Impact of Opencast Coal Mining

opencast mining far outweighs the short term economic benefits.1 The NCBOE argues that the restored land is almost invariably improved in quality after mining and that derelict land is a significant component of opencast mining land requirements.2 Both of these perspectives are,

Open-pit mining Wikipedia

Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal 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 useful ore or rocks

Negative impacts of open-cast mining on the environment

Jul 07, 2015· A major part of iron ore, non-ferrous metals, brown coal, building materials and minerals for industry is being excavated in open-cast mines. This type of mining has a deep impact on the natural strata. Open-cast mining changes geological, hydrological and geotechnical conditions. It influences the existing ecological system and landscape.

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.

Environmental impact of mining Wikipedia

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have
