The evolution of coal permeability is very complex under the influence of coupled multiple
processes. This is the primary motivation why numerous coal permeability models have …

Underground coal thermal treatment is a clean method of coal utilisation. Pyrolytic semi-
coke provides a good storage vehicle for CO 2 geological storage, but there are few studies …

Coal has a complex pore network, which affects the reserves and production capacity of
coalbed methane. To analyze the feasibility of coal seam heat injection mining and improve …

Realized by the conversion of the electromagnetic energy into thermal energy, microwave
heating can be a sound method to enhance coalbed methane (CBM) recovery. Although the …

Adsorption of gases such as methane and carbon dioxide in coal is an exothermic process.
Under isentropic conditions (fully insulated condition), the ejected heat results in an additive …

It is important to understand the gas flow properties in coal and sandstone under different
stress conditions for underground carbon dioxide storage and coal bed gas drainage in …

Experiments have observed that coal permeability experiences significant change when
temperature varies from room temperature up to 100° C. However, current permeability …

Heat injection into coal seams can stimulate coalbed methane reservoirs to enhance the
recovery of coalbed methane. However, the effects of temperature change induced coal-gas …

Heat injection is considered to be an effective technique to increase Coalbed methane
(CBM) production, which indicates the important role of temperature in gas flow. In this …

When adsorbing gas is injected into coal, the gas fills in the fractures quickly and a pressure
difference between matrix and fractures is created. Because of this difference, there is a …
