Our staff has just finished solving all todays Guardian Post daily crossword and the answer for Methane found in coal mines can be found below Methane found in coal mines ANSWER. Drainage of methane from coal seams and from overlying formations is an effective technique to alleviate methane emission problems in coal mines. However in order for methane drainage to be successful and produce the expected results methane drainage systems must be designed according to specific geologic conditions such as gassiness of the coal seam and overlying strata specific gas emissions of the mine and coal.
Firedamp is a mining term for a set of explosive gases found in mines. Its mostly made up of methane and methane is often an interchangeable term when miners talk about firedamp. Methane CH4 is a colourless odourless highly flammable and highly explosive noxious gas.
It occurs naturally in coal seams and shale deposits and is a major component of the natural gas that we burn for energy. FIREDAMP The crossword clue Gas mixture mainly of methane found in coal mines published 1 times and has 1 unique answers on our system. Possible Answers From Our DataBase.

Historically if such a pocket was highly pressurized it was termed a bag of foulness. Methane has at least 28 times more warming potential than carbon dioxide. Coal mining is responsible for about 7 percent of all US.
Methane emissions according to the EPA and research shows the amount of methane leaking from abandoned coal mines will grow as more mines close. Methane emission in coal mines. Emission rates were influenced markedly by the presence of abandoned oil and gas wells in the vicinity of the mine.
Such wells appeared to increase the flow rate of methane into the mine by a factor of 2 to 30 in an active mine in the Pittsburgh coal seam. The analysis which surveyed 432 proposed coal mines found that the methane emissions from these mines which are currently in construction or pre-construction planning would amount to 135 million tonnes of methane annually - a 30 per cent increase over current emissions.
