Coal mining became a largescale industry from the 18 th century to 1950s. With coal being the main energy source, the low cost and low abundance of this material made coal mining important for the growth of the economic industry. Despite a shift in the use of energy source from coal to ...
Methane from Coal. The natural gas methane is a byproduct of coalification the process where plant materials were gradually buried, compressed, and heated, resulting in the various ranks of coal. In Pennsylvania, natural gas is extracted from coal as coalbed methane and as coal mine methane. Coalbed methane comes from (unmined) coal.
Apr 06, 2010· Of coal mines and methane. ... the detectors are supposed to automatically deenergize the equipment. ... and they also have a gas division and they make a lot of money selling gas .

Fireman in the Coal Mines Early coal mines were troubled by methane gas; the coal mine management paid someone to disperse the gas by igniting it with a flame. As you can imagine this was a very dangerous occupation and these "firemen" literally risked their lives every time they entered a gaseous area of the mine.
Jurisdictional Problem • Oil and gas wells are regulated by states • MSHA only has jurisdiction over mines – Only when a coal mine is near an oil or gas well is MSHA able to take enforcement actions – Most oil and gas drillers and coal mines have been cooperative in dealing with this potential issue
Mining Topic: Methane Detection and Monitoring CDC. Jan 08, 2019· Methane Detection and Monitoring What is the health and safety problem? The use of machinemounted methane monitors is required by federal regulations to alert miners to the presence of potentially dangerous concentrations of methane while mining coal.

CDC Mining Contract Wireless Sensor Network NIOSH. This sensor was designed to serve three purposes: (1) conduct absolute pressure measurement and recording in both nonpermissible and permissible areas of a coal mine (2) explore methane gas cloud detection, measurement, and visualization and (3) provide a wireless sensor node network.
Mar 28, 2007· Methane gas has also been detected in product coal recovery tunnels, including in the cavity surrounding the coal chutes. Recent incidents have occurred in several Bowen Basin Open Cut coal mines where flammable and toxic gases have been found in areas where normal mining activities are being undertaken.
Mar 07, 2018· Explosion of methane gas is the most common source of mining accidents, mainly in coals mines. Methane, an odorless, colorless gas, is trapped in mines as part of the coal formation process. When coal is formed from compressed plant matter, methane is produced as a byproduct.
Coal Mine Methane Sources. ... it is necessary to supplement the ventilation with a degasification system consisting of a network of boreholes and gas pipelines. In abandoned mines and surface mines, methane might also escape to the atmosphere through natural fissures or other diffuse sources. ... Surface mines, from which methane in the coal ...
Sep 26, 2016· Methane is a colourless, tasteless, odourless gas and has the chemical formula CH4 – methane is the main component of natural gas. For those who didn''t listen to their chemistry teacher at school, it is made up of one atom of carbon and four atoms of hydrogen.
2012 Coal Operators'' Conference The University of Wollongong 340 16 – 17 February 2012 CHALLENGES OF GAS MONITORING AND INTERPRETATION IN UNDERGROUND COAL MINES FOLLOWING AN EMERGENCY Peter Mason1 ABSTRACT: While modern coal mines are commonly equipped with a range of gas monitoring resources during normal operations, they are often lacking in their contingency planning when a mine
Several things make mining dangerous, chief among them the possible exposure to methane. This gas especially is dangerous because it cannot be seen or smelled, and appears naturally from the ground. When miners began to realize how dangerous methane was, they started exploring ways to detect it. CANARIES IN A COAL MINE
