Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat. ...

Author: Jim Howorganized industries—mining has an ancient and venerable history (Gregory, 1980). To understand modern mining practices,it is useful to trace the evolution of mining technology,which(as pointed out earlier in this chapter) has paralleled human evolution and the advance of civilization.

Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts, to large open cut and long wall mines. Mining at this scale requires the use of heavy equipment in many different forms. History
Opencast workings or opencuts are surface excavations in which the overburden is stripped by hand or mechanical excavators, thereby laying bare the mineral, which is afterwards broken and loaded ...

Here we present two different accounts of the history of coal mining in County Durham. The first comes from The Victoria History of the Counties of England - Durham, published in three volumes in 1907. It ...
Before mining can commence the land needs to be cleared of timber and vegetation. 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.
[PDF]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.
The Friends of St Aidans care for 'Oddball', a Bucyrus Erie BE 1150 Walking Dragline Excavator, which was used in opencast/surface coal mining. This giant machine is preserved on the site where it last worked at Swillington, Leeds. Public Open Days throughout the year.
Open pit mining -- or strip mining -- is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient.
Open pit mining - also called open cut mining or open cast mining - is a surface mining technique used to extract rocks and minerals. It requires large-scale equipment, including shovels and drills. Motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines.
[PDF]Open cast mining is a type of surface mining in which mineral resources are removed from the earth through large holes or pits dug into the surface. The term "open cast mining" is used most commonly in Great Britain. In the United States, open cast mining is usually called open-pit or open-cut mining.
Surface mined coal statistics. This survey, previously known as 'the Opencast Coal Survey', has been renamed to 'Survey of Surface Mined Coal' to better reflect modern methods used to extract shallow coal and align with terminology used by the Coal Authority and the coal extraction industry.
