The specific surface of coal particles is determined for 370 samples of Kuznetsk Basin coal with a wide range of metamorphic development. Low-temperature adsorption on a Sorbi N.4.1 instrument is employed, at liquid nitrogen temperature and various partial pressures. The specific surface is calculated by the Brunauer–Emmett–Teller (BET) method. In comparison with coal of poor and high metamorphic development, the specific surface is 0.23–3.90 m2/g higher for Zh, KZh, and K coal with vitrinite reflection coefficient 0.93–1.39% and yield of volatiles 20–36%.
