Global methane emissions from coal mining to

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 ...

LIFE CYCLE ASSESSMENT OF GREENHOUSE GAS

2017-6-20  Methane emissions from gas chains represent between 5% and 20% of total upstream4 GHG emissions. For coal chains, methane emissions are mainly generated by underground coal mining and range from 7% to 70% of upstream GHG emissions. Figure 5: GHG emissions upstream contributions 4. Without considering GHG emissions from electricity generation.

Environmental impact of mining-associated carbon

In recent years, concern has been increasing regarding the carbon emissions generated by mining activities. China is an extremely large coal producer (3695 Mt/2015) and consumer (3698 Mt/2015), and Shanxi Province (i.e., a major coal-producing province in China) is a crucial element in China’s energy conservation and emission reduction goals. In this study, the Pingshuo mining area (PMA) in ...
