Structural control on pore-fracture characteristics of coals from Xinjing coal mine, northeastern Qinshui basin, China

Deformation characteristics and pore structure of coals from Xinjing coal mine have been studied, as well as the control mechanism of structural deformation on coal structure characteristics, based on observation in coal mine and deformation analysis of typical coal samples, combined with microscopic observation and mercury intrusion porosimetry (MIP). The research has revealed that coals of Xinjing coal mine mainly suffered from brittle...
