The specific surface and porosity of bituminous coal (rank Zh) are studied. The textural characteristics of Kuznetsk Basin coal are determined by various methods: for example, the specific surface by the Brunauer–Emmett–Teller (BET) method; the micropore volume by the comparative t-plot method; and the mesopore volume by the Barrett–Joyner–Halenda method from the low-temperature (77 K) absorption–desorption isotherms obtained by means of a Micromeritics ASAP 2020 instrument. The specific surface is small, and mesopore structure predominates for all the coal samples. Analysis of the pore structure of Kuznetsk Basin coal reveals their macro- and microstructure and provides information regarding their adsorption properties.

研究了烟煤（Zh级）的比表面和孔隙率。库兹涅茨克盆地煤的结构特征通过多种方法确定：例如，通过 Brunauer-Emmett-Teller (BET) 方法确定比表面积；比较t -plot法的微孔体积；和通过 Barrett-Joyner-Halenda 方法从通过 Micromeritics ASAP 2020 仪器获得的低温（77 K）吸收-解吸等温线得到的中孔体积。煤样比表面积小，中孔结构占优势。对库兹涅茨克盆地煤的孔隙结构的分析揭示了它们的宏观和微观结构，并提供了有关它们的吸附特性的信息。
