Feb 18 2021 1. Introduction. Coal is a solid combustible organic rock produced by complex chemical reactions and phase transformations of petrified peat made from decaying plants that left their imprints in mud and clay as they hardened into shale stone. 1 Since a coal body is a porous medium with a very developed pore structure most scholars adopt the dual-pore medium model of the coal body.
