Tectonic coal, formed after the intact coal being subjected to long-term intense squeezing,
shearing and deformation, is characterised by brittle or ductile damaged coal body, with the …

Exploitation of coalbed methane (CBM) has dual advantages of not only providing
alternative clean-energy but also effectively reducing the proneness for gas outbursts. CBM …

Microscopic pores significantly impact the coalbed methane (CBM) storage, hence gas
energy recovery and gas-related problems mitigation. However, the quantitative relationship …

Abstract Changes of heat and energy during methane adsorption and desorption are
essential factors affecting the production of coalbed methane. To characterize adsorption …

Microfracture structures of coal seams are the key parameters in the context of enhanced
coalbed methane (ECBM) recovery as they determine permeability and productivity …

To study the influence of coal metamorphism on the pore system development
characteristics of deep coal reservoirs, coal samples of different ranks were collected as …

Pores in coal and their connectivity are important properties of coal, providing network or
channels for gas storage and migration within coal, eg during the coalbed methane (CBM) …

The characteristics of pore-fracture networks, as well as their evolution in coal during
loading, are important for exploration of coalbed methane. In this study, the evolution of …

Based on results of laboratory tests and a study of exploration wells, we investigate
Carboniferous–Permian unconventional natural gases in lateral extension and vertical …

Methane is primarily stored in coal matrix pores and pore size distribution has an important
effect on gas adsorption/desorption. Investigation of the relationship between pore size …
