HIGHLIGHTS
- who: September and collaborators from the Shandong University of Science and Technology, China have published the paper: True triaxial experimental study on the in uence of axial pressure on coal permeability, in the Journal: (JOURNAL)
- what: In this study, the change law of coal seam permeability with axial pressure was studied through the triaxial stress permeability test device under the context of fixed gas and confining pressures, and the influence of vertical formation stress on gas drainage efficiency was calculated using the COMSOL numerical analysis software. gas accumulation zones (Guo et_al, 2019; Lin et_al, 2022 . . .
