During coal mining in the past decades, gas has been regarded as a disaster factor. However, with the concept of resource maximization being put forward, we have seen green energy, which inspires humans to mine and use. In recent years, the methods, theories, and equipment for the exploitation and utilization of coal seam gas (CSG) or coalbed methane (CBM) have quickly developed. What’s more, with shallow resource depletion, CSG/CBM extraction has transferred to deep areas. The deep gas environment is different from that of shallow areas. Therefore, there are many difficulties during CSG/CBM extraction, which need methods or technical innovation to overcome them.

In the in-situ stress environment, the state of CSG/CBM is steady. Once it is affected by the artificial disturbance, the gas adsorption equilibrium will be broken. Gas will then be desorbed from the coal matrix. When gas enters coal fractures, diffusion and seepage form in the fractures within different scales. During CSG/CBM extraction, the mechanism of gas adsorption/desorption, diffusion, seepage, and other flow modes require us to pay more attention. In addition, some dynamic disasters related to gas flow may be caused during CSG/CBM extraction. The role of gas and how it affects the forming and development process of dynamic disasters cannot be neglected. Therefore, the mechanism of dynamic disasters needs further research, as well as prevention and control theories and methods.

This Special Issue aims to bring together original research and review articles highlighting recent advances and challenges in the progress of gas flow during coal seam gas extraction and gas-bearing disasters, We welcome submissions focusing on gas adsorption and analytical characteristics, gas flow law and extraction, gas disaster mechanism, gas disaster monitoring and early warning, gas disaster prevention and control technology measures and related research on dynamic disasters of gas-bearing coal.
