Summary: The effects of surfactant adsorption on the surface physicochemical properties of coal dust were investigated using infrared spectroscopy, zeta potential, and dust control efficiency experiments. The results showed that anionic surfactant was more easily adsorbed on coal dust surface compared to nonionic surfactant, and the combination of anionic-nonionic surfactants improved the adsorption of surfactant molecules on the coal dust surface. The developed compound surfactant (B+D) significantly enhanced the dust control efficiency in field tests. Surfactant adsorption capacity was not found to be a critical factor in optimizing surfactants for enhancing solution wettability. Overall, this study was important in selecting surfactants for improved coal dust control performance.

Summary: An airflow-particle two-phase coupling calculation model of the human upper respiratory tract was established to study the dust exposure amount and coal dust deposition rule in the coal mine environment under different labor intensity. The simulation results showed that the total deposition fraction of 1 μm dust was the smallest and less influenced by respiratory intensity. As the dust particle size increased, the dust deposition fraction in the nasal cavity, pharynx, and larynx increased and concentrated in the front of the nasal cavity. The possibility of dust being transported into the lungs decreased with the increase of dust particle size or labor intensity. A fitting function of the 7.07 μm dust escape rate and labor intensity was obtained.

Summary: The use of nanofluids in enhanced oil recovery processes has gained attention due to the possibility to increase oil recovery from mature oil fields. Silica nanoparticles are widely used for nanofluid formulations, but there are obstacles such as stability, environmental and economic aspects, and the need for suitable large-scale production processes. This study evaluates oil recovery using silica-based nanofluids from different sources under various operational conditions, and demonstrates that silica from rice husk ash has comparable efficiency to other synthetic silica nanoparticles.

Summary: The accurate identification of gas migration channels and enrichment regions plays a crucial role in the utilization of gas resources and the safe production of coal mines. This study conducted a similarity simulation of inclined coal seam group multiple mining, focusing on the 1930 Coal Mine in Xinjiang, China. The results revealed significant asymmetric characteristics in the frequency, angle, and width of mining-induced fractures during inclined coal seam group multiple mining. Based on these characteristics, a step-by-step method for determining gas migration channels and enrichment regions was proposed. The surface well gas extraction test in the mining area validated the experimental results and showed satisfactory extraction effects.

Summary: Uniaxially graded cyclic loading and unloading experiments were conducted on fractured red sandstone with different initial stress levels to investigate the effect of horizontal stress in fractured blocks on the stability of overlying strata. The results showed that the elastic modulus decreased nonlinearly with increasing cycle number, the load-unload response ratio fluctuated around 1, and the irreversible strain increased rapidly and steadily. The proportion of elastic energy tended to increase linearly, while the proportion of dissipated strain energy tended to decrease. Additionally, the damage variable, based on the dissipation strain energy definition, exhibited a parabolic growth trend with increasing cycle number. Both the irreversible strain and damage variables showed an increasing-decreasing-increasing trend as the initial stress level increased. A stability criterion for voussoir beam structures based on the effect of repeated mining disturbances on horizontal thrust was proposed. This research has important implications for the stability of overlying strata.

Summary: The dust particles generated during coal mining and processing are usually removed by spray dust reduction. The contact wetting and wrapping process of dust particles by droplets were analyzed under different particle size ratios and initial droplet velocities. The results showed that the larger the particle size ratio, the more variation in the spreading coefficient. When the particle size ratio was more than 2, the droplets could completely wrap the coal dust particles. The optimized parameters achieved an average settling efficiency of 86.2% for respirable dust in the mine return air duct.

Summary: SiO2-H2O nanofluids have great potential for water injection in coal seams. The particle size of SiO2 NPs affects the stability and wettability of the nanofluids. Larger particle size leads to more aggregation and sedimentation, while smaller particle size results in lower surface tension and contact angle. The nanofluids show time-varying characteristics, with the low stability stage being the optimal period for enhancing water injection. This research provides theoretical support for using SiO2-H2O nanofluids in coal seam water injection.

Summary: This study investigates the relationship between coal dust surface characteristics and crush degrees, and their impact on the efficiency of surfactant solution spray for dust control. The results show that the surface characteristics of coal dust are positively correlated with the crush degree. The reduction in dust size enhances the pore volume and gas adsorption, making it more difficult for the surfactant solution to capture coal dust. The increased gas adsorption and pore structures on the dust surface weaken the dust removal efficiency of the surfactant solution.

Summary: In this study, two surfactant solutions were prepared to wet coal dust, and the surface tension, contact angle, and functional group composition were measured. The results showed that the SDDS/AEO-9 solution had lower surface tension and critical micelle concentration compared to the SDDS/SDBS solution at the same mixing ratio. The wetting effect on coal dust was best when the ratio of SDDS:SDBS was 2:1. The study found that aliphatic hydrocarbons and surface tension had a positive correlation with contact angle in SDDS/SDBS solutions, while hydroxyl groups had a negative correlation. Only surface tension and contact angle showed a significant linear relationship in the SDDS/AEO-9 solution. The combination of surfactants played an important role in the wetting process of coal.

Summary: The rapid development of nanotechnology in the past decade has created numerous opportunities for researchers and engineers. Nanofluids, created by suspending nanoparticles in conventional heat transfer carriers, offer significant advantages in thermal properties. This study addresses the challenge of nanofluid stability and analyzes various forces and physical phenomena affecting the stability. Stable and highly conductive nanofluids can be produced through one-step or two-step production methods, but both methods face the problem of nanoparticle agglomeration.
