Dear Colleagues,

During coal mining in past decades, gas is regarded as disaster factor. However, with the concept of resource maximization putting forward, it has been seen green resource, which inspire human to mine and use. In recent years, the methods, theories and equipments for exploitation and utilization of coal seam gas (CSG) or coalbed methane have developped fast. What’s more, with shallow resources depletion, CSG/CBM extraction has also transferred to deep area. Deep gas enviroment is obviously different from that of shallow area. Therefore, there are a serizes of difficulties during CSG/CBM extraction, which need method or technical innovation to overcome them.

In the in-situ stress environment, CSG/CBM is at steady state. Once it is affected by artificial disturbance, gas adsorption equilibrium will be broken. Then gas will be desorbed from coal matrix. When gas enters into coal fractures, the diffusion and seepage will be formed in the fractures within different scale. So during CSG/CBM extraction, the mechanism of gas adsorption/desorption, diffusion, seepage and others flow modes need pay more and more attention. In addition, some dynamic disasters related to gas flow may be caused during CSG/CBM extraction. The role of gas can’t be neglected, and how does it affect the forming and development process of dynamic disaster. Therefore, the mechanism of dynamic disasters needs to be research, and the prevention and control theory and method also need study.

This Topical Collection aims to bring together original research and review articles highlighting recent advances and challenges in 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 a series of related research on dynamic disasters of gas-bearing coal.

Based on the above research, this Collection intends to carry out the following research, including but not limited to

• Method and equipments of coal seam gas/coalbed methane extraction;
• Technology of coal seam gas/coalbed methane utilization;
• Gas flow of CBM/CSG;
• Gas adsorption, diffusion and seepage;
• Mechanism of coal/rock dynamic disaster within gas;
• Prevention and control theory of dynamic disaster of gas-bearing coal;
• Control technology of coal and rock dynamic disaster;
• Mechanics and dynamics of gas-bearing coal;
• Acoustoelectric characteristics of gas-bearing coal flow process;
• Deformation law of coal and rock in gas extraction;
• Stress response of coal containing gas under load deformation and failure.
