TL;DR: In this article, the authors investigated the adsorption capacity, swelling effect and permeability characteristic of coal seams with and without tectonic damage, the natural coal and reconstituted coal manufactured via simulating in situ geological conditions were investigated.

TL;DR: In this article, the authors explored the evolution and formation mechanisms of closed pores, regarding which there is a lack of knowledge and understanding and provided a novel method to investigate the mechanism of geological CO 2 sequestration.

TL;DR: In this article, an anisotropy index was introduced to quantitatively characterize the anisotropic porosity, swelling and permeability of coal during CO2-ECBM or CGS injection.

TL;DR: In this paper, the authors show that prefracturing can dramatically decrease the IPLRi, stress sensitivity coefficient and PALR of coal seams, which may be the potential and effective measure to enhence the injectivity of CO2 in coal seams.

TL;DR: In this paper, a series of corresponding coal permeability tests were conducted under different adsorption pressures (2 − 10 MPa), moisture states (dry and wet), temperatures (35 − 65 °C), coal ranks (Ro,max = 0.68% − 3.33%), effective stresses (3 − 10MPa).
