Various mining activities, particularly open pit, affect the topsoil and subsoil to a great extent by changing the natural soil characteristics e.g. texture, grain size, moisture, pH, organic matter, nutrients etc. In an ideal open-pit situation it is desired that the soil horizons within the selected mining limits are clearly defined. Topsoil and subsoil are removed separately, preferably by ...
2 天前 A decision by planners to block a new opencast coal mine in north-east England should “bring down the curtain” on such sites, Friends of the Earth have said. After a three-hour hearing on ...
Opencast mining is one of the most intensive forms of landscape change mediated by humans. Mining significantly alters both natural and anthropogenic systems and returning this land to desirable or historical states is often prevented due to the irreversible nature of mining activities. Additionally, communities living near or over resources ...
24/07/2012 Particularly, opencast mining activities severely alter the topography and the physical conditions of the atmosphere, and inversely affect plant life, soil conditions, wildlife habitats, and water resources in the mining area and in its immediate surroundings. As a result of above mentioned factors, post-mining landscapes lose their previous aesthetic, ecological and socioeconomic values. If ...

01/06/2016 Opencast coal mining is an anthropogenic activity that changes the antecedent soil profile, and the physical, chemical and biological properties. The compaction activities of large machinery play a great effect on reconstructed soil pore structure in opencast coal-mine dump, so it is an important work to reconstruct a suitable soil pore structure for vegetation growth during the land ...
Open-pit coal mining in the United Kingdom is in decline. Output has fallen every year since 2010. In 2010, the United Kingdom was forecast to produce about ten million tonnes (9,800,000 long tons; 11,000,000 short tons) of coal a year from open-pit mines.Most came from Scotland, with the largest operator there being the Scottish Coal subsidiary of Scottish Resources Group.

Mining Production Activities. 3. The advantages of open pit mining. There are a number of advantages of open pit mining when compared to Underground Mining: Open pits can sometimes be brought into production quickly. Underground mining requires development (shaft sinking, adits, declines etc.) which might take years before production can start. However, design construction of
07/10/2020 Concor Opencast Mining, a well-known opencast mining business amongst South Africa’s surface mines, is strategically positioning itself to achieve significant growth in the short-term future. This in part can be attributed to the greater objectives of Level 1 BEE parent company Southern Palace Group, which is looking to maximise on the value its companies and business units have to
A generic methodology for cumulative impact assessment of opencast mining projects has been developed with special reference to air quality assessment. It involved questionnaire checklists and a geographical information system for scoping of the impact assessment study, and the ISCST3 air quality dispersion model for the analysis of impacts. Its use was illustrated by a case study at an ...
Danger now looms for school-going children and livestock in the form of huge pits from opencast mining activities at the defunct copper producing site. The pits are widening and deepening each ...

Mining Production Activities. 4. Disadvantages of open pit mining. However, disadvantages when compared to Underground Mining also exist: Very large amounts of waste rock are mined. This creates costs as well as environmental issues with waste rock disposal; Major disruption of surface: pit footprint, waste dumps. High visual impact, especially strip mining. After closure, rehabilitation may ...
“The Northern Cape is a water-scarce region and, with mining activities set to expand in the area, the impact of opencast mining on the water quality and quantity is of great environmental concern.

Opencast mining was never meant to be a substitute for deep coal mining. Unfortunately, it is now considered an asset, not in the sense that it is considered imperative that we get the coal, but in the sense that it is a cheap form of fuel that is quickly mined and, as we say, in the wagon, with the money in the bank in a few days or a few weeks. I am a former mining engineer and I know that ...

The Council has agreed a series of actions to address the issue of opencast mining restoration in East Ayrshire following the collapse of Scottish Coal and Aardvark earlier this year. These actions are in relation to a number of issues, including local employment and business impacts, environmental considerations, planning applications and compliance monitoring and restoration of existing ...

Sites date back to the 1940s. Outlines drawn on 1:25000 scale topographic bases. The majority of the collection was deposited with the National Geological Records Centre by the Coal Authority in ...
from Sunday Herald, 27 January 2013 Private companies are planning a massive expansion of opencast coal mining in Scotland, according to information released by the UK government’s Coal Authority. As many as 21 developments are being proposed across the central belt and in the south to dig out more than 37 tonnes of coal. Many are extensions of existing mines, but some are major new sites.
