Impact of greenhouse gases on surface coal mining in Brazil

The coal life cycle emissions were equal to 3.29 × 10 −2 kg CO 2eq per kg of coal, of which direct emissions accounted for 98.3% of GHG, in which the major part was due to fugitive methane emissions from surface mining and post-mining coal crushing and handling operations. Additionally, the results of a sensitivity analysis showed that the ...
