Energy and resource extraction and processing

Impacts of energy and resource extraction on the coast mostly result from the development expansion and maintenance of ports for processing and export and the infrastructure needed to extract diffuse energy sources such as coal-seam gas The main contributors of processing and export are nearshore liquefied natural gas (LNG) processing plants LNG and minerals (coal iron

According to the World Coal Association more than 6 185 million tonnes (Mt) of hard coal was mined from coal mines around the world as of 2012 Coals mines use surface mining for coal deposits buried less than 200 feet underground In this type of mining giant machines remove top-soil and layers of rock to expose large beds of coal After coal extraction the topsoil is

Coal mining is only a temporary use of land so it is vital that rehabilitation of land takes place once mining operations have stopped In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine covering the period from the start of operations until well after mining has finished Underground mining There are two main

Coal one of the most important primary fossil fuels a solid carbon-rich material usually brown or black that most often occurs in stratified sedimentary deposits which may later be subjected to high temperatures and pressures during mountain building resulting in the development of anthracite and even graphite

Coal Mining Methods Underground Mining Longwall Room and Pillar Mining Longwall mining and room-and-pillar mining are the two basic methods of mining coal underground with room-and-pillar being the traditional method in the United States Both methods are well suited to extracting the relatively flat coalbeds (or coal seams) typical of the United States Although

Coal mining is the process of getting coal out of the ground It is part of the mining industry Coal is used as a resource for making electricity Extraction Surface mining is done when the coal is near the surface Coal miners remove the soil above the coal The coal can then be removed without the coal miners having to go deep underground

coal extraction process Coal Mining and Processing Surface mining can be used when the coal is buried less than 200 feet underground In surface mining giant machines remove the topsoil and layers of rock to expose large beds of coal Once the mining is finished the dirt and rock are returned to the pit the topsoil is replaced and the area is replanted

The Mining Process Once a mining lease has been awarded to an operator exploration (i e evaluation of the resource) takes place followed by a planning and development process before excavation or mining begins The initial task is to gain access to the seam from the surface by some means (shafts drifts etc – see Access to Seam from surface section for these terms)
