Journal ArticleDOI
Macromolecular and pore structures of Chinese tectonically deformed coal studied by atomic force microscopy
TL;DR: In this article, the macromolecular and nanoscale pores of different types of tectonically deformed coals were characterized by AFM and the nanostructures of coal differed in terms of the metamorphism degree, deformation degree, and deformation properties.
Journal ArticleDOI
Micro-pores and fractures of coals analysed by field emission scanning electron microscopy and fractal theory
TL;DR: In this article, the micro-pores and fractures of six coal samples with different metamorphic degrees (R o,m ǫ = 0.75-2.80%) were analyzed using field emission scanning electron microscopy (FESEM).
Journal ArticleDOI
Changes in the anisotropic permeability of low-rank coal under varying effective stress in Fukang mining area, China
TL;DR: In this article, the authors collected 4 types of cubic coal samples (samples cut parallel to face and butt cleats and perpendicular to the bedding plane) from the Fukang mining area in China to investigate the anisotropic characteristics of P-wave velocity, fractures and permeability under varying effective stresses from 3.5 to 8.5
Journal ArticleDOI
The evolution and formation mechanisms of closed pores in coal
TL;DR: In this article, the authors explored the evolution and formation mechanisms of closed pores, regarding which there is a lack of knowledge and understanding and provided a novel method to investigate the mechanism of geological CO 2 sequestration.
Journal ArticleDOI
Fractal study of adsorption-pores in pulverized coals with various metamorphism degrees using N2 adsorption, X-ray scattering and image analysis methods
TL;DR: In this article, the pore structure (pore volume and specific surface area) and adsorption performance (Langmuir volume and Langmuir pressure) of 12 different rank coal samples were investigated by liquid nitrogen adaption experiment (LNA) and methane isotherm (MIMO) experiment, and the fractal characteristics of these coals were studied by three fractal dimensions D1, D2 and D3 acquired from small angle X-ray scattering (SAXS), respectively.
