Law of gas migration and enrichment in goaf based on three-dimensional porosity model
Meikuang Anquan, 2021 The distribution of porosity in the goaf has an important influence on the fluid flow in the goaf. Based on the O-shape ring theory and the masonry beam theory, a three-dimensional distribution function of porosity was proposed.
