Based on maceral determination, Ro test, ultimate-proximate analysis, LND, TEM, and adsorption/desorption test, composition and adsorption/desorption characteristics of deformed high-rank coals in the south of Qinshui basin were systematically studied. Results show that, 1) macro-and micro-pore fractures of high-rank coals change with the deformation degree; 2) chemical compositions of deformed high-rank coals show remarkably differences; and 3) the adsorption/desorption of deformed high-rank coals shows intimate relations with the physical and chemical compositions.
