2020-5-20  The gas content of the current global underground hard coal mix 1 thus is in the range between 13 and 18 m 3 /t for mining depths from 450 to 1120 m. For surface mines, the gas content of hard coal is 3–5 m 3 /t for depths from 50 to 200 m and 0.77 m 3 /t at the constant depth of 50 m for brown coal.. However, the gas content per ton of coal and the emission factor are not equal due to ...

IMPACTS OF COAL MINING IN BALOCHISTAN

Methane emission from coal mining depends on the mining methods, depth of coal mining, coal quality and entrapped gas content in coal seams, however the rate of emission of methane should range between (1-10 m3/ton) during mining and maximum 3.5 m3/ton in case of post mining, Watson, L.D., and L. Smith, 2004 , but higher limits measured
