Child Labour / Collieries of Whitehaven /England's first Undersea mine/Haig Mine Museum /Klondike in Cleator Moor / / Whitehaven's mining professor/ Whitehaven grew from a sleepy fishing village to a busy industrial port largely because the nearby hills had rich coal seams that were so close to the surface they even outcropped on the valley side.
Coal: Coal, solid, usually brown or black, carbon-rich material that most often occurs in stratified sedimentary deposits. It is one of the most important of the primary fossil fuels.
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods.

Early coal extraction was small-scale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell pits.As well as drift mines, small scale shaft mining was used.
Types of surface mining . Strip mining: This process involves the method of extracting the mineral by removing soil and rock which are deposited on the surface.Coal and Lignite are the two principle minerals that are extracted through this method.
Water. Large quantities of water are used in mining operations for cooling machinery, dust suppression, cleaning, fire-fighting and drinking. Water supplies are normally carried in steel pipes from surface to points close to the work places, with flexible hoses used for the final connections.
LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.
Underground mining is approved out when the rocks, minerals, or gemstone are positioned at coldness far beneath the ground to be extract with outside mining.
Transporting coal from the Powder River Basin to proposed west coast terminal sites would require unprecedented levels of regional rail usage.
3 INTRODUCTION The mining of coal in the eastern United States has had significant effects on wildlife populations and their habitats. The extraction of coal by various means (deep mining, longwall

Indian Mining Industry has been a major mineral producer in Asia and globally. Currently it is the global producer of chromite, coal, iron ore and bauxite while enjoying economic growth during the nineties.
Coal mining: Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy.
