“…Globally, Coalbed Methane (CBM), including coal mine methane (CMM) captured from the underground coal mining operations, is attracting growing attention mainly from the perspective of climate change caused by greenhouse gas (GHG) emission . However, China has two additional and very compelling reasons for addressing the issue—decreasing coal mining accidents and developing cleaner energy resources to improve air quality in cities…”

China is vigorously promoting the development of coalbed methane (CBM) resources because CBM is cleaner than coal and a hazardous gas in coal mining. However, the CBM production in China is significantly lower than that in other coal‐rich countries, such as Australia and the United States. In this paper, the main problems hindering CBM development in China are discussed to provide management suggestions for the government. These key problems include exploration and development techniques, the overlap of mining rights, management, financial supporting policy, investment environment, regulations, and market conditions. The results of this study indicate that to improve the development of the CBM industry in China, national and local governments must enact specific and exercisable regulations to increase financial support, improve technology, increase investment in CBM exploration, strengthen public project establishment, and improve the reform of CBM exploration and development policies.

“…Adsorption of methane on coal plays a crucial role in a variety of natural and technological processes, such as gas outbursts in coal mines, , global warming caused by methane emissions, evaluation and exploitation of coal methane resources, and methane storage . Natural gas, mainly consisted of methane, is retained in coal beds in three main forms: (1) free gas in cleats, fractures, and macropores, (2) gas dissolved in water formations, and (3) gas adsorbed in micropores of width <2 nm and mesopores of width from 2 to 50 nm.…”

The quenched solid density functional theory (QSDFT) is employed to study methane adsorption on coal at geological conditions. The main focus is made on coal deformation in the course of adsorption that may result in either expansion/swelling or contraction, depending upon the pressure, temperature, and pore size. Two qualitatively different types of deformation behavior were found depending upon the pore width. Type I shows a monotonic expansion in the whole pressure range. This behavior is characteristic for the smallest pores <1.3σff (0.5 nm) that cannot accommodate more than one layer of methane. Type II displays contraction at low pressures followed by expansion. Type II behavior was found for several groups of pores, which can accommodate dense packing with an integer number (from 2 to 6) of adsorbed layers. The results of the QSDFT model are compared to literature experimental data, and the model is employed to study the adsorption behavior of model coals at elevated pressures and temperatures. We established the relationships between the methane capacity and the solvation pressure that it exerts on the coal matrix and the depth of coal bed for pores of different sizes. We found that the coal deformation depends upon the bed depth, and at different depths, it either swells or contracts depending upon the pore size distribution. The implications of these findings for evaluating coal gas resources and coal mine recovery are discussed.

“…First, emission inventories in the underground coal mining sectors have focused on CH 4 emissions over the last three decades and not necessarily on CO 2 emissions. This was, in part, because of safety and regulatory concerns to ensure reduced risks of accidents in underground mines ( Banerjee and Dhar, 1996 ; Banerjee et al., 1994 ). This made reporting of CH 4 emissions relatively intuitive within the UNFCCC reporting standards.…”
