An Improved Approach to Estimate Methane …

2017-9-28 · China, the largest coal producer in the world, is responsible for over 50% of the total global methane (CH4) emissions from coal mining. However, the current emission inventory of CH4 from coal mining has large uncertainties because of the lack of localized emission factors (EFs). In this study, province-level CH4 EFs from coal mining in China were developed based on the data analysis of coal

Impact of greenhouse gases on surface coal mining in

Coal ore extraction involves both surface (open-pit) and underground mining techniques. The method selected depends on a variety of factors, including the nature and location of the deposit, size, depth, and grade of the deposit (Norgate and Haque, 2010).Surface mining operates in two distinct stages, overburden removal and coal extraction, as well as the recovery of the mined area.
