Mining Methods. Continuous; Bord-and-pillar; Summary: Cook Colliery is a currently operating as a Bord and Pillar mine. Cook Colliery is an underground mine that currently only exploits the Argo Seam. Conventional retreating longwall mining was previously used to mine some of the reserve, with inseam development by continuous miners used to
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

The term colliery includes the coal mine, with its buildings and appurtenances; the mine proper is underground. The entrance to it is by a drift, a slope, or a shaft. "Stripping,"—which is quarrying, and not mining at all,—is only possible where there is an outcrop of a thick bed of coal.
Colliery. At first, mining was carried out entirely by conven-tional methods (drill and blast) until the introduction of mechanized mining using a continuous miner (CM) during 2004. Pillar extraction experience at XCSA Pillar extraction was initially carried out making use of a total pillar extraction mining method at the Arthur Taylor Colliery

The technology was far in advance of any coal mining method in the late medieval period and was considered one of the industrial wonders of the age. During the 17th century a number of advances in mining techniques were made, such the use of test boring to find suitable deposits and chain pumps, driven by water wheels, to drain the collieries.

Oct 21, 2010· Longwall mining is the underground coal mining method mostly used in Turkey. Most of the collieries in the country produce coal from thick coal seams. The three methods mainly used worldwide in thick coal seams are longwall top coal caving (LTCC), multi-slice longwall (MSL), and, single pass longwall (SPL) methods. As shearer-loaders and roof supports get larger in size, the SPL method
