Topic Information

Dear Colleagues,

China’s natural energy reserves are characterized by “rich coal, poor oil, and little gas”. This unique foundation has established that coal will be as predominant an energy source for the nation in the foreseeable future as it is now. According to a forecast made by the Chinese Academy of Engineering, the proportion of coal consumption to total energy consumption will remain at 50% by 2050. In addition, under the dual carbon targets of “carbon peaking and carbon neutrality”, coal carbon still needs to continue to play its crucial role as a “ballast” in the energy system, with energy security being the highest priority. However, with the development of China's shallow coal resources, coal sources are becoming increasingly depleted, and deep mining has become a strategic demand for energy in China. As deeper layers of coal seams are accessed to facilitate coal mining, these seams show increasingly obvious characteristics of high geo-stress, strong gas adsorption, and low permeability, resulting in significant changes in the mining environment. Under the influence of mining disturbances, coal and gas outburst and rock burst disasters are becoming increasingly serious threats. The intertwining nature of these threats has contributed to the complexity and intricacy disaster mechanisms, making disaster prevention and control increasingly difficult. Therefore, this research topic endeavor is concentrated on the complex issues surrounding deep coal resource extraction, specifically in relation to coal and gas outbursts, rock bursts, and multifaceted coal–rock dynamic disasters. This research topic aims to elucidate the challenges of disaster prevention, and to propose innovative methods that will reduce the incidence of disasters in the civil and coal mine domains, among others. This research topic seeks to address a multitude of areas within civil and mining engineering fields, aiming at advancing a sustainable global landscape. We welcome both original research and review articles, including but not limited to the following topics:

• Coal and gas outburst prevention technology;
• Rock burst prevention methods;
• Regional disaster risk assessment;
• Risk assessments of the systematic classification of natural hazards;
• Disaster risk reduction frameworks;
• Methodologies for natural hazard warning alerts;
• Coal mine ventilation;
• Management of natural disaster reduction;

Deep coal mining is essential for energy use and sustainable development. In a situation where coal–rock–gas dynamic disasters are prone to occur in coal seam variation areas affected by different degrees of roof angle during deep coal seam mining, a disaster energy equation considering the influence of roof elastic energy is established, and the disaster energy criterion considering the influence of roof elastic energy is derived and introduced into COMSOL6.1 software for numerical simulation. The results show that, compared with the simple change of coal thickness and coal strength, the stress concentration degree of a thick coal belt with small structure is higher, and the maximum horizontal stress can reach 47.6 MPa. There is a short rise area of gas pressure in front of the working face, and the maximum gas pressure reaches 0.82 MPa. The plastic deformation of the coal body in a small-structure thick coal belt is the largest, and the maximum value is 18.04 m³. The simulated elastic energy of rock mass is about one third of that of coal mass, and the influence of the elastic energy of roof rock on a disaster cannot be ignored. When the coal seam is excavated from thin to thick with a small-structural thick coal belt, the peak value of the energy criterion in front of the excavation face is the largest, and the maximum value is 1.42, indicating that a dynamic disaster can occur and the harm degree will be the greatest. It is easy to cause a coal and gas outburst accident when the excavation face enters a soft coal seam from a hard coal seam and a small-structural thick coal belt from a thin coal belt. Practice shows that holistic prevention and control measures based on high-pressure water jet slit drilling technology make it possible to increase the average pure volume of gas extracted from the drilled holes by 4.5 times, and the stress peak is shifted to the deeper part of the coal wall. At the same time, the use of encrypted drilling in local small tectonic thick coal zones can effectively attenuate the concentrated stress in the coal seam and reduce the expansion energy of gas. This study enriches our understanding of the mechanism of coal–rock–gas dynamic disaster, provides methods and a basis for the prevention and control of dynamic disaster in deep coal seam variation areas, and promotes the sustainable development of energy.
