May 20, 2020· 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 ...

The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil.It is approximately 42 gigajoules or 11.630 megawatt-hours, although as different crude oils have different calorific values, the exact value is defined by convention; several slightly different definitions exist.The toe is sometimes used for large amounts of energy.
