"Structure feature and evolution mechanism of pores in different metamo" by Jiangang Ren, Zhimin Song et al.
Abstract Coal pore structure plays a crucial role in the adsorption, migration and production of coalbed gas, and its feature and evolution are mainly controlled by metamorphism and deformation. In this study, the original and tectonically deformed structures of middle- and high-rank coal samples (R , = 1.14–3.44%) were obtained through low-temperature nitrogen adsorption (LTNA), small-angle X-ray scattering (SAXS) and scanning electron microscopy (SEM) to analyze the pore structure of both...
