Challenges in underground environment In coal mines, the major emission is of methane. The methane released during and after mining operations is called Coal mine methane (CMM). In recent years, there have been many 83 International Journal of Engineering Research Technology (IJERT) Vol. 2 Issue 5, May 2013
Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...
Continuous Monitoring of Environmental Parameters in Underground Coal Mines Robert G. Peluso Mine Safety and Health Administration, Box 18233, Cochrans Mill Road, Pittsburgh, Pennsylvania 15236 The development of personal and fixedsite ...
Coal Mine Information System. 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.

Inseam seismic methods have been widely used in underground coal mine exploitation since early 80''s. They are helpful for identification of stress concentration zones or to locate geological disturbances within the coal seam. Usually, such surveys are optimized to perform seismic tomography. Therefore, sources and receivers are located on the opposite sides of the longwall.
In the US, coal mining is a shrinking industry. In 1923, there were about 883,000 coal miners; today there are about 53,000.; Working in coal mines is dangerous — miners have to deal with toxic ...
Nov 19, 2007· The Queensland Mines Inspectorate says mining community, including manufacturers and suppliers, must be aware of earth fault current limiter parameters in underground coal mines.
May 22, 2020· So coal is still an important energy source. To date most of the coal production is from underground coal mining operation. In the case of underground mining, the working space is relatively confined.
underground mines. The production from surface mines appears to have reached a plateau. To cope with the growing demand, increased amounts of coal will inevitably come from deep underground mines. In some with more than 1,000 m of overburden. At these depths coal mining has encountered two new problems: ground control and ventilation.
Since 2001, disasters due to explosions in underground coal mines have caused 59 deaths in the mining industry, including 29 deaths in a single mine explosion in 2010. In the most recent of these, investigators concluded that the presence of float coal dust in underground airways played a significant role in the propagation of the flame ...
Jul 14, 2020· Also, highergrade coal is available only deep down, and the decline of underground coal production, seen over the years, should concern us. The reasons why underground mines have not performed well are higher costs of mining, difficult geomining conditions, lack of skillsets, etc.

Coal mining Coal mining Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many .
underground mine is associated with large amount of risk mainly due to gas and coal dust explosion. To reduce the risk associated with underground mining, efficient and adequate ventilation is preferred. Improving the amount of air ventilation would improve the level of safety in coal mines.
IN THE UNDERGROUND COAL MINES Henryk BADURA, Henryk STABLA 7 Introduction One of the basic conditions of safe work in the underground coal mines is preservation of suitable physical and chemical parameters of the mine atmosphere [1]. Composition

Methane emissions may also be associated with coalmine subsidence. A study of subsidence events in Madisonville,, found that large volumes of methane Ky. that had collected in underground mines were leaking to the surface through fracture networks caused by mine subsidence (Craft and others, 1986). In 2015, a Walmart in Madisonville
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and ...
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The development of personal and fixedsite continuous monitoring devices offers the potential to improve monitoring of the work environment and control worker exposure in underground coal mines. Such devices could allow continuous measurement as opposed to periodic measurement of dust concentrations.
available information, the Underground Coal Mining Safety Research Collaboration (UCMSRC) was asked by Participants from the British Columbia Ministry of Mines and Energy to research the topic of the use of explosions proof stoppings in underground coal mines and to collate information for future reference in a single report. This report is
Underground coal mining requires advance instrumentation for sustainable growth and safety of miners. Many parameters, such as emission of gases, strata conditions, temperature, air velocity ...
underground mining as all coal seams are exploited 90 % or IRACST – Engineering Science and Technology: An International Journal (ESTIJ), ISSN:,,, June 2013
However mining the coal has proven to be very dangerous and has caused many accidental deaths over the years. Keeping this in mind we have designed an intelligent system which can be used on helmets of these underground coal miners and can monitor/analyze a few major hazardous parameters found in these mines in real time.
