Present and Future Potentiality of Coal Bed Methane Gas Exploration and Production in Indian Coal Fields

Methane Mitigation in Indian Coal Mining

Association of methane with coal poses a serious explosion risk in underground coal mining. Besides, it is a potent green house gases significantly contributing to global warming. Therefore, its commercial exploitation is being widely recognised as (a) a fuel resource to bridge the energy gap (b) making coal mining safer (c) providing cleaner energy and (d) checking the building of green house ...

Determination and assessment of coal bed methane potential using rock engineering systems

The presence of methane in coal mines is one of the major problems in underground coal mines. Every year, in underground coal mines, a lot of casualties due to outbursts and explosions of methane gas is occurring. Existence of this gas in the mines not only creates a difficult and dangerous situation for work but also makes it more expensive. The release of this gas to the air causes a further ...

Estimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine

Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' safety. The purpose of this work is to provide the prediction maps for the C1, C2, and B2...

Hydrogen-Rich Gas Production by Cogasification of Coal and Biomass in an Intermittent Fluidized Bed

This paper presents the experimental results of cogasification of coal and biomass in an intermittent fluidized bed reactor, aiming to investigate the influences of operation parameters such as gasification temperature (T), steam to biomass mass ratio (SBMR), and biomass to coal mass ratio (BCMR) on hydrogen-rich (H2-rich) gas production. The results show that H2-rich gas free of N2 dilution is...
