1. Introduction
The significance of coal mine gas control in the field of engineering cannot be underestimated. Gas disasters are one of the most common and destructive types that occur in coal mines [1]. Due to the depletion of shallow resources in recent years, mining depths in coal mines have increased year by year [2,3]. With the presence of micro-pores and the low permeability and high adsorption of coal seams being common issues, the problem of gas in mining has become one of the main issues that restricts their safe development [4,5]. Coal mine gas control is an important requirement for safe and efficient coal production. However, gas control and utilization face a series of challenges in coal and gas outburst prevention, intelligent gas disaster warnings, gas explosions, and efficient coal bed methane extraction. This Special Issue, “Advanced Methodology and Analysis in Coal Mine Gas Control”, aims to report the latest research in coal mine gas control in terms of basic theories, key technology, and equipment development to improve gas disaster prevention in coal mining processes.
2. Overview of Contributions
This Special Issue’s contributions can be categorized into three key themes:
- Mechanism and control technology of gas disasters
Ma et al. (contribution 7) established normal and tangential analysis models of ore rock impacting shaft walls. Du et al. (contribution 9) described a gas explosion simulation that combines the chemical reaction mechanism and tunnel structure. Liu et al. (contribution 1) suggested that coal mine gas accidents could be prevented to a large extent by encouraging good management culture in enterprise management and discourage illegal production behaviors. Xia et al. (contribution 11) reported the quantitative characterization of the degree of damage caused by ore rock flow and suggested a mechanism of damage to the shaft wall in the storage section of the ore pass. Jin et al. (contribution 6) took coal and rock samples subjected to the coupled effects of water, temperature, and dynamic loads as the research object and discussed their mechanical properties. Fu et al. (contribution 12) studied the roof movement and ground pressure evolution characteristics of an ultralong working face in a shallow coal seam with a high mining height. Gao et al. (contribution 2) developed a deformation and damage mechanism for the surrounding rock of auxiliary retracement channels and a method for determining the reasonable spacing of two retracement channels at the end of the mining period. Pu et al. (contribution 4) established two sets of active support schemes for controlling the surrounding rock in thick coal seams with ultra-large span open-off cuts and proposed an optimized support scheme through numerical simulation.

- Gas disaster monitoring and early warning technology
Lutyński et al. (contribution 17) presented the results of an analysis of the hazards posed by coal mine dust and methane in coal preparation plants of hard coal mines in Poland. Zhang et al. (contribution 16) determined the upper limit of time to ensure safe operation under different failure modes; they found that the acquired temperature distribution characteristics under failure modes can be used as a reference for the design, inspection, and status warning of flameproof cable boxes for coal mines. Guo et al. (contribution 3) established a XGBoost–GR–stacking gas outburst early warning model to demonstrate high accuracy and practical performance.

- Gas extraction and unloading
Hao et al. (contribution 14) developed a novel borehole sealed quality detection device for the extraction of gas in a coal mine. Yu et al. (contribution 13) employed a model of the equivalent fissure to reveal the heat transfer mechanism between the rock matrix and CO2. Xie et al. (contribution 10) proposed a dual method of hydraulic fracturing of key layers of overlying rock layers combined with the pre-extraction of gas via large-diameter caving boreholes. Shu (contribution 8) examined gas extraction technology in the goaf of an L-shaped borehole in the mining fissure zone of a short-distance coal seam group. Ma et al. (contribution 15) showed that stress directly affects the gas desorption of coal and plays a decisive role in the gas desorption and emission characteristics of water-bearing coal in the stress-affected zone. Zhang et al. (contribution 5) constructed a molecular structure model of anthracite and coking coal–rock compound models containing different calcite and kaolinite contents.
3. Conclusions
The articles collected in our Special Issue highlight the great progress being made in gas storage, disaster mechanisms, monitoring and warnings, precise prevention and control, and efficient extraction, and provide a valuable frontier perspective and technical guidance for mine gas control. At present, mine gas control still faces many challenges. With continuous improvements to the intelligent construction of coal mines, future research will continue to improve the level of comprehensive gas control and development with more scientific technology, more advanced equipment, and enhanced management techniques. This will enable the coal industry to develop in a more efficient, green, and low-carbon direction, and contribute further to the realization of the “double carbon” goal and the protection of energy security.
