The problem of global warming and climate change has attracted global attention, and
reducing the concentration of CO2 in the atmosphere is an important step towards solving …

Carbon dioxide (CO2)-enhanced coalbed methane recovery (CO2-ECBM) is a critical way to
increase methane production and reduce greenhouse gas (CO2 and CH4) emissions. As …

Methane extraction in deep coal seams is a multi-field coupling process affected by multiple
factors, and a systematic multi-field coupling theory is of guiding significance for ensuring …

CO 2-enhanced coalbed methane (CO 2-ECBM) recovery has the triple benefits of
recovering clean resources, ensuring coal mine safety, and achieving CO 2 geological …

Injection of gas mixture (CO 2/N 2) into coal seam can both enhance methane recovery and
reduce carbon dioxide emission. Coal permeability determines the mass transport speed …

With the objective of achieving an 'emission peak and carbon neutrality', the injection of CO
2 into deep unmineable coal seams or abandoned mines can enhance the methane …

It is of great scientific and engineering significances to reveal the coupling mechanism of
microscale and macroscale permeabilities in coalbed methane (CBM) reservoirs. In this …

Microwave heating is an efficient thermal stimulation approach in developing coalbed
methane (CBM). In this paper, a new microwave heating technology for CBM is proposed …

Abstract Flue gas (CO 2/N 2) injection into coal seam is promised to achieve both reduction
of greenhouse gas emission and enhancement of methane recovery. An improved heat …

Adsorption-induced swelling of coal matrix tends to close some of the pores, and thus can
significantly lower the permeability of coals. The influence of such a heterogeneous pore …
