Resource types, formation, distribution and prospects of coal-measure gas

Microstructural characterisation of organic matter pores in coal-measure shale

“…The meso-macropore volume was obtained with the Barrette Joynere Halenda (BJH) method, and the micropores volume (0.64-2 nm) was determined applying the SF (Saito-Foley) model. Pore size distributions were determined using the BJH method with N 2 adsorption data (Jarvie et al, 2007;Sun et al, 2016;Zhou et al, 2016;Ko et al, 2017;Shao et al, 2017;Li et al, 2018a;Zou et al, 2019) .…”

“…As an important component of unconventional gas resource, the coal-measure shale gas has great potential for resource exploration and broad prospects for development in China. According to the assessment of the Ministry of Land of China in 2012, the exploitable resources for marinecontinental transitional coal-measure shale gas are estimated to be 8.97×10 12 m 3 (Wang, 2013;Dong et al, 2015;Zou et al, 2016Zou et al, , 2019. On the one hand, coal-measure shale deposits vertically with coal, sandstone and limestone, and the thickness for a single continuous deposition layer is generally less than 20 m, which is unfavorable for the exploration and development of coal-measure shale gas resources.…”

State Management Of Strategic Natural Resources

“…An analysis of articles indexed by Web of science over the past 20 years on this topic allows you to distribute them in the following areas: broad-based articles dealing with various types of natural resources, linking them to the problem of economic security of the country (Ivanitsky & Privalov, 2016;Kryukov et al, 2017;Lebedev et al, 2015;Ulanov & Ulanova, 2019); articles directly linking the problem of resources with political issues (Keypour & Hendla, 2019;Seliverstov & Krivonosov, 2019;Zelenskaya, 2018); articles on certain types of resources (Golovina, 2017;Gulyanov et al, 2019;Hashim, 2010;Kudeyarov, 2019;Laverov & Distler, 2003;Panova & Sinitsyna, 2019;Privalov & Privalova, 2017;Sergeev & Ponomarenko, 2015;Vasiltsova, 2016;Zou et al, 2019); articles related to certain territories, especially the far North or the Arctic shelf Agarkov et al, 2018;Berezikov, 2019;Carayannis et al, 2017;Cherepovitsyn et al, 2018;Kozhevnikov, 2019;Lipina et al, 2018;Morgunova & Telegina, 2019;Zaikov et al, 2017;Zinoviev, 2017); articles on international relations and trade (Orazgaliyev & Araral, 2019;Orlov, 2016;Privalov & Li, 2015;Vinokurov & Krasnoyarova, 2018).…”

Theoretical Study and Numerical Simulation Research on the Effect of Coal-Rock Interface on Multistaged Fracturing in the Roof of Outburst Coal Seam

“…Coalbed methane (CBM) is a kind of unconventional natural gas that reserves in coal seam, which has been successfully produced in Ordos, Qinshui, and Junggar basins in China [1][2][3]. CBM production has the advantages of reducing greenhouse effect, utilizing clearer energy, increasing safety level of coal mining, and improving energy structure [4].…”
