Creep characteristics and constitutive model of coal under triaxial stress and gas pressure
Creep behavior is one of the most important mechanical behaviors of coal. In the present study, we systematically carried out a series of creep experiments of briquette samples under triaxial compression and gas pressure.

The effect of adsorption-induced swelling on porosity based on the transient coal swelling model
Coal swelling induced by gas adsorption is a well-known phenomenon. In order to enhance coalbed methane production and greenhouse gases sequestration, adsorption phase should be understood deeply, and it is the most basic and the most important ...

Role of adsorption and swelling on the dynamics of gas injection in coal [PDF]
An experimental technique is presented to perform gas injection experiments on coal cores confined by an external hydrostatic pressure, which makes use of the so‐called transient step method. The experiments are intended to improve the knowledge on the different mechanisms acting during CO2 storage in coal seams, in particular, those related to ...

Proton NMR relaxometry as a useful tool to evaluate swelling processes in peat soils [PDF]
Dramatic physical and physico-chemical changes in soil properties may arise due to temperature and moisture variations as well as swelling of soil organic matter (SOM) under constant conditions.
