ACP - Estimating CH4, CO2 and CO emissions from coal ...
The regional emission estimates of CO 2 , which were determined to be 1.21±0.75 and 1.12±0.38 t s −1 , are in the lower range of emission inventories. CO mass balance emissions of 10.1±3.6 and 10.7±4.4 kg s −1 for the USCB are slightly higher than the emission inventory values.

Greenhouse Gas Emissions From Coal Mining Activities
2018-1-1 With very significant CO 2, CH 4, and N 2 O emissions from different mining activities as fugitive emissions, coal mining is a major contributor to the buildup of GHGs in the atmosphere. These gases allow solar energy to reach the earth's surface but delay that energy's escape into space, and thus effectively trapping heat in the lower atmosphere.

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 ...

CO2 emissions by fuel - Our World in Data
Carbon dioxide (CO 2) emissions from energy and material production can arise from various sources and fuel type: coal, oil, gas, cement production and gas flaring.. As global and national energy systems have transitioned over centuries and decades, the contribution of different fuel sources to CO 2 emissions has changed both geographically and temporally.
