Influences of hydraulic fracturing on microfractures of high-rank coal under different in-situ stress conditions
TL;DR: In this paper, high-rank coal samples from Chengzhuang and Sihe Mine were selected for hydraulic fracturing simulation experiments, using stereoscopic microfracture scanning and binarization image processing methods, and the mean aperture, surface density, connectivity, mean length and fracture porosity of micro-fractures were compared and analyzed under different in-situ stress conditions before and after hydraulic fracturing.

Characterizing the shape, size, and distribution heterogeneity of pore-fractures in high rank coal based on X-ray CT image analysis and mercury intrusion porosimetry
TL;DR: The shape, size, and surface characters of pore-fractures in coal are the basis for understanding the occurrence and migration of coalbed methane (CBM), which requires quantitative characterization as mentioned in this paper.

Potential impact of CO2 injection into coal matrix in molecular terms
TL;DR: In this paper, the authors used a high-order coal macromolecular model to reveal specific processes of coal macrocular rearrangement caused by CO2 injection through molecular dynamics and the potential impact of this injection on the sequestration and mechanical properties of CO2 in coal matrix was investigated.

Heterogeneity of pore structure of late Paleozoic transitional facies coal-bearing shale in the Southern North China and its main controlling factors
TL;DR: In this article, the pore structure of coal-bearing shale is investigated in the Southern North China, using low-temperature nitrogen adsorption with two-dimensional non-local density functional theory (2D-NLDFT), field emission scanning electron microscopy combined with argon-ion milling, and high-pressure mercury injection.

Stress degradation mechanism of coal macromolecular structure: Insights from molecular dynamics simulation and quantum chemistry calculations
TL;DR: In this article, the degradation mechanism of the macromolecular structure of low-rank coal during shearing was studied using the Wender coal structure model, and two chemical bond breakage types were observed: tensile break and shear break.
