Anisotropic Mechanical Properties and the Permeability Evolution of Cubic Coal Under True Triaxial Stress Paths
TL;DR: In this article, the authors divided pre-existing fracture systems of cubic coal into three flow planes: a bedding plane, face cleat plane, and butt cleat planes, and analyzed anisotropic mechanical and flow property responses of coal after failure by model fitting, CT scan reconstruction and fractal representation.
Journal ArticleDOI
Permeability evolution and mesoscopic cracking behaviors of liquid nitrogen cryogenic freeze fracturing in low permeable and heterogeneous coal
Guangzhi Yin,Delei Shang,Minghui Li,Huang Jie,Tiancheng Gong,Zhenlong Song,Deng Bozhi,Chao Liu,Zhicheng Xie +8 more
TL;DR: In this paper, the authors examined the mesoscopic cracking behaviors of coal with different water contents and cleat-fracture systems in the context of liquid nitrogen cryogenic freeze fracturing (FF) by maximizing the underlying heterogeneity of coal.
Journal ArticleDOI
Analysis for Green Mine (phosphate) performance of China: An evaluation index system
Delei Shang,Guangzhi Yin,Xiaoshuang Li,Yaoji Li,Jiang Changbao,Kang Xiangtao,Chao Liu,Chi Zhang +7 more
TL;DR: In this paper, the pith of Green Mine is introduced, which is a critical part of recourses policy for Green Mining in China, and an unprecedented trial, evaluation index system for Green Mine (phosphate) is presented.
Journal ArticleDOI
Deformation and permeability evolution of coals considering the effect of beddings
TL;DR: In this article, an analytical model for stress-strain relationship of coals containing beddings is developed to quantify the bedding effects under true triaxial stress conditions.
Journal ArticleDOI
Permeability characteristics of layered composite coal-rock under true triaxial stress conditions
TL;DR: In this article, the authors measured the coal and sandstone permeability under true triaxial stress conditions and found that the coal seams and sandstones formations have major influences on the evolution of coal rock permeability.
