[PERSON] and [PERSON] [16] discussed the increase in underground mining activity, the risks involved in hard rock mining for minerals, and the impact of the global steel shortage on mining operations. The paper presents two designs for rock reinforcement systems to prevent fatal rockfalls in underground excavations, including a preliminary design and an improved model of the rock bolt. Laboratory tests were conducted on the improved bolt design,which yielded an average of 200 kN during dynamic testing and successfully met the reliability and performance requirements. The improved bolt design requires less steel and has the same performance as current rock reinforcement systems. Measuring gas pressure is crucial for assessing the methane hazard in coal mines; however, existing methods are limited. [PERSON] et al. [17] used artificial neural networks to estimate the methane seam pressure, developing two models that demonstrated a high correlation with the reference values determined through sorption isotherms. The models had prediction errors of 2.59% and 3.04% for average and maximum pressure values, respectively, with determination coefficients exceeding 0.99. These results indicate the potential for practical application of this method to improve methane hazard assessments in coal mining. [PERSON] et al. [18] described the results of biomonitoring research at an underground gas storage facility in Poland. The study focused on the presence of hydrogen sulfide- and sulphate-reducing bacteria in reservoir waters and natural gas. The results indicate that microbiological processes, specifically microbial sulfate reduction, were the main cause of hydrogen sulfide formation at the facility, and methods are suggested for controlling and maintaining the hydrogen sulfide in natural gas at a low level. [PERSON] et al. [19] presented the design of a new type of fiber Bragg grating (FBG) dynamo bolt with a linear viscoelastic adhesive layer modeled by a standard linear solid model. A shear strain transfer model and instantaneous and quasistatic strain transfer functions of the surface-bonded FBG sensor were established and validated through uniaxial tensile tests and long-term constant load tensile tests. The application of the FBG sensing technology in the field demonstrated successful monitoring of the stress of the rock bolt in a mining area. [PERSON] et al. [20] discuss the development of a kinematic and dynamic model for roadheaders, which includes their obstacle crossing ability, and its use in path rectification planning. Field experiments were carried out to verify the effectiveness of the dynamic model and a roadway grid model was established based on actual working conditions. The authors proposed a path rectification planning and tracking algorithm based on particle swarm optimization, which was verified using MATLAB simulations. The algorithm can provide technical support for the intelligence of roadheaders and unmanned mining and can contribute to the structural optimization and intelligent travel control of roadheaders. [PERSON] et al. [21] presented a simulation cutting experiment system for a drum shearer using similarity theory. Simulated coal samples were prepared using an orthogonal experiment method, and their density and compressive strength were analyzed using the range analysis method. The results showed that the density and compressive strength of the simulated coal samples were related to the mass proportion of cement and sand and the proportion of cement, respectively. The self-designed simulation cutting experiment system could effectively carry out experiments and obtain cutting condition signals that could distinguish between various cutting modes. [PERSON] et al. [22] discuss the importance of space mining to solve ecological energy and mining problems and the need for geological surveys using drilling methods to achieve this. Drilling methods are important for studying extraterrestrial objects for geological, life searching, and geoengineering studies.
