The publication Coal in Pennsylvania (PDF) includes information about the geologic history of coal in the commonwealth, where it occurs, and how it is mined and used. In Pennsylvania, operators mine coal at the surface and underground. The Pennsylvania Geological Survey has a page-size map (PDF) of the state's coalfields. Some of the largest, most modern and productive underground coal mines ...

Surface mining output of coal exceeded that from underground mines from 1957 through 2006. Since 2007, the underground coal production has surpassed that from surface mining again 4. From 1880 to 1920, coal ranked first in the value of Arkansas' mineral and fuel output, but since 1922 the value of oil has exceeded that of coal.

Coal Mining History. The discovery of coal in Colonial ia was first reported by Colonel William Byrd in 1701, who noted coal occurrences on the banks of the James River near the town of Manakin (Brown and others, 1952). Coal was likely being used for domestic purposes even earlier than that by Huguenot settlers (Wilkes, 1988).

Mining. Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines.

The Missouri Geological Survey, working under cooperative agreement with the U.S. Department of the Interior's Office of Surface Mining (OSM), inventoried, electronically scanned and archived 1,193 underground mine maps, of which 428 are for coal mines and 765 are for non-coal mines.

The International Journal of Coal Geology deals with fundamental and applied aspects of the geology and petrology of coal, oil/gas source rocks and shale gas resources. The journal aims to advance the exploration, exploitation and utilization of these resources, and to stimulate environmental awareness as well as advancement of engineering for effective resource management.

Minerals Yearbook (Volume III. -- Area Reports: International)Listed below are chapters from the Minerals Yearbook (Volume III. -- Area Reports: International).

The Coal Mine Information System (CMIS) is a repository for historical coal mining information in Indiana. It was developed through a cooperative agreement between the Indiana Geological Survey and the Indiana Department of Natural Resources, Division of Reclamation. In addition to historical ...

This chapter discusses the production of mineral, petroleum, and coal deposits. The commercial production of minerals were restricted to industrial materials such as silica, sand and gravel, limestone, clay, and building aggregate. Commercially viable mineral deposits were restricted to western Sarawak and west of the Lupar Line.

The biggest coal deposit by volume is the Powder River Basin in Wyoming and Montana, which the USGS estimated to have 1.07 trillion short tons of in-place coal resources, 162 billion short tons of recoverable coal resources, and 25 billion short tons of economic coal resources (also called reserves) in .

Coal mining geology activities include delineating in more detail any geological features that may affect the mine layout, such as individual faults and igneous intrusions, as well as monitoring any variations in the seam that may impact on the quality of the coal produced. They are also concerned

Coal-Forming Environments: A generalized diagram of a swamp, showing how water depth, preservation conditions, plant types, and plant productivity can vary in different parts of the swamp. These variations will yield different types of coal. Illustration by the West ia Geological and Economic Survey.

Other articles where Coal seam is discussed: sedimentary rock: Coal: to the various kinds of coal: initially brown coal or lignite, then soft or bituminous coal, and finally, with metamorphism, hard or anthracite coal. In the geologic record, coal occurs in beds, called seams, which are blanketlike coal deposits a few centimetres to metres or hundreds of metres thick.

The largest reserves of coal are located in Merit Pila, Sarawak and in Maliau and Malibau, Sabah. Production in 2016 decreased to 2,414,765 tonnes from 2,559,444 tonnes produced in 2015 that came from eight mines, all in Sarawak. Malaysia import large quantities of coal for its domestic requirements.

Malaysia has coal resources of about 1.9 billion Mt (Gt) and about 1.5 Gt of the coal resources in the country is located in Sarawak. More that 300 Mt of coal is located in Sabah. Coal in the interior regions of Malaysia had not been exploited in 2010 due to lack of infrastructure. Investment

Major coal reserves in Malaysia are mostly located in Sabah and Sarawak with smaller reserves in Perak, Perlis and Selangor. The Labuan coal field produced coal starting 1848 until 1912. As of 1986, coal reserve in Malaysia was 965 million tons in which mostly are bituminous coal. The total known coal area is 5,823 km 2.

Geological Setting of Australasian Coal Deposits Abstract Coal was discovered in Australia in 1791 by William Bryant, a convict, near the mouth of the Hunter River at Newcastle, New South Wales (NSW). Later discoveries were made along the Brisbane River and ncar Ipswich in the 1820s. Mining commenced in Australia in 1799, also in NSW.
