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 given rise to danger of dump failures. Further, steeper open-pit slopes are prone to failure. These failures lead
It was burning coal extracted in the Welsh valleys, including from the UK's largest opencast coal mine, Ffos-y-fran. Opencast coal mining totally destroys the ecosystems above the coal, as vast pits are dug by machines, releasing dust into the air. This settles on homes and farm land nearby.

While 93 coal mines produced all of South Africa's coal in 2016, that number increased 59%, to 148 mines, by 2016. Production, however, increased by only about 10%, indicative of a trend towards smaller mines. But with smaller mines and shorter lifespans, mining companies are targeting new areas for coal mining.

Responsible for opencast thermal coal mining, coal washing and sizing, and distribution of blended coals from a range of owned and third party coal mines to domestic and export customers. In particular, I ensured compliance with health and safety requirements and consent conditions, and developed and implemented medium to long term operational plans. I worked to extend the life of our opencast
The negative impact of mining upon agricultural lands is not limited to opencast mining operations. Underground coal mining's impact on agriculture and water is not negligible, with the potential for subsidence, cracks, or sinkholes forming above areas where underground mining has taken place. The risk is significantly heightened if high extraction methods of mining are employed, e.g., high
Contour mining is associated with coal. This bed of coal is located at an elevation in a mountain range or any other hilly area. It is a method of strip or surface mining. It is also referred to as Bench mining. The coal is extracted from a mountainous area where it is not possible to extract the entire seam using mountain top removal mining
At the Ffos-y-fran opencast reclamation site, researchers also discovered no changes in metals consequential upon the addition of their PAS100 biofertiliser. 48 However, others 24,27 caution about the metals that can be mobilised by dissolved organic carbons from composted green waste, including both those listed above and As, which tends to be common in coal mining spoils, if not at this site .
Coal mining deep underground involves a higher safety risk than coal mined in opencast pits. However, modern coal mines have rigorous safety procedures, health and safety standards and worker education andFroth flotation cells at training, which have led to significantGoedehoop Colliery are used improvements in safety levels in bothfor fine coal beneficiation.Photograph courtesy of underground

Coal mining impact the environment adversely by causing interference with groundwater quantity and change of surface and groundwater regimes and currents, and their pollution by opencast waste waters, noise and vibration extend, land pollution by the opencast waste waters, etc. Owing to its low quality and sizable spread, significant overburden is excavated for efficient production. This

Coal mining has razed forests, blackened rivers, contaminated the air with dust, and created waste mounds. Those who live there say the region has become a moonscape from which many are desperate to escape. Then there's the human cost. At the heart of this report are the testimonies of the indigenous Shors, a Turkic people whose survival and beliefs are intimately tied to the nature around
Richard Solly, coordinator of London Mining Network wrote: for nearly fourteen years, I have been working in support of communities affected by the Cerrejon coal mine, a vast opencast mine in the province of La Guajira, Colombia. I have just returned from a visit to the area, my first in ten years - and it was a massive, eye-opening shock.

2019-7-1 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.
Coal mining in the United Kingdom dates back to Roman times and occurred in many different parts of the country. Britain's coalfields are associated with Northumberland and Durham, North and South Wales, Yorkshire, the Scottish Central Belt, Lancashire, Cumbria, the East and West Midlands and Kent.After 1970, coal mining quickly collapsed and had practically disappeared by the 21st century.

The project is the biggest ever investment outside of its home country made by Brazilian mining group Vale, which, in 2008, started developing Mozambique's largest ever coal mine over the country's Moatize coalfield. At the completion ceremony, Brazil's Foreign Minister said Vale was in Mozambique to stay – and noted that was the meaning of the word 'Nacala' in the local Macula

Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common. For example, surface mining accounts for around 80% of production in Australia; while in the USA it is used for about 67% of production.
Surface mining – also known as opencast or opencut mining – is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited – 90% or more of the coal can be recovered.
ACT, a Decentralized Autonomous Organization for Citizen Action, is using the Ether Cryptocurrency to support a Community Fighting Opencast Coal Mining in Wales. A community in the Upper Rhymney Valley of Wales, United Kingdom that has had enough of dirty coal will fundraise on a new blockchain platform that accepts only the Ether cryptocurrency.
