TLDR
In this paper, a series of laboratory experiments were performed to firstly analyze the characteristics of the pore structure in low-rank coal (R o 1000nm), with a poor development of mesopores (100-1000nm).About:

Effect of coalification and maceration on pore differential development characteristics of high-volatile bituminous coal
TL;DR: In this article , the pore structure of high-volatile bituminous coal (HBC) was detected using a scanning electron microscope, mercury intrusion porosimetry, low-temperature N2 adsorption, and lowtemperature CO2 adaption across multiple length scales and the effect of coalification and maceral on pore differential development law was analyzed.

Coalbed methane: A review
TL;DR: In this paper, it is shown that the micropores are where most methane adsorption occurs in coal seams, and the methane molecule may actually stretch, minutely, the pore and thus with de-gassing of the reservoir, could result in matrix shrinkage, allowing opening of the fracture (cleat) system in the coal and thus enhancing permeability.

Petrophysical characterization of coals by low-field nuclear magnetic resonance (NMR)
TL;DR: Wang et al. as mentioned in this paper proposed a new NMR-based per-meability model that better estimates the permeability of coals, which has potential applications for NMR well logging in coalbed methane exploration.
