Hardcover. Condizione: new. Hardcover. With the gradual depletion of coal resources and the increasing exploitation intensity of these resources in mining areas, coal mining has entered a phase of deep mining. In deep environments, the coal and rock mass in the "three high and one low" stress environment will have a more intense mechanical response, accompanied by more serious engineering disasters, such as coal and gas outbursts, rock bursts, gas dust explosions, roadway deformation, and other disaster problems.The aim is to clarify the latest progress made in coal mine safety monitoring, process control, and disaster prevention, and to further identify the common characteristics and development trends of this Special Issue in terms of theoretical understanding, key technologies, and engineering practice, thereby providing references for future research and coal mine safety production. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…

Hardcover. Condizione: new. Hardcover. The contributions in this Special Issue highlight advances in understanding dynamic disasters, coal mine gas behavior, gas extraction in low-permeability seams, gas explosions, and adsorption and desorption processes. The contributions provide comprehensive insights into the mechanisms of dynamic disasters, including coal-rock failure, rockbursts, and outburst-prone structures, which are critical for improving safety in deep and complex mining environments. Research on coal bed gas adsorption, desorption, diffusion, and emission has clarified the factors influencing gas migration and over-limit events, supporting more accurate risk assessment and early warning strategies. Studies on gas extraction technologies and permeability enhancement methods offer practical solutions for low-permeability coal seams, including hydraulic slotting, borehole sealing, and unloading techniques, improving gas drainage efficiency and mitigating disaster risks. Furthermore, investigations into mining process control, roadway layout optimization, and filling operations demonstrate the effectiveness of engineering strategies and numerical simulations in enhancing operational safety and extraction efficiency. Together, these contributions provide valuable guidance for future research and practical applications in coal mine safety and process optimization. This item is printed on demand.
