Abstract: To address the challenge of dust pollution control in long-distance roadway blasting operations in coal mines, a comprehensive numerical simulation analysis was conducted on the 15101 working face of a specific mine. Utilizing FLUENT software, a three-dimensional model of the roadway was established. Based on the k-ε turbulence equation and the discrete phase tracking model, a systematic investigation was carried out on the airflow dynamics characteristics of the exhaust and combined pressure-exhaust ventilation schemes in long-distance roadways, as well as the differences in dust dispersion characteristics and control effectiveness in the blasting operation areas. The results indicate that while the initial wind speed at the exhaust ventilation outlet reaches 10 m/s, it rapidly decays to 1-2 m/s in the rear section. Additionally, vortices tend to form on the left front side, while the wind speed on the right side remains relatively low, leading to dust accumulation and dispersion, resulting in suboptimal dust suppression. In contrast, the long-pressure short-exhaust ventilation system demonstrates more uniform wind speed distribution, with the pressure section forming a high-speed core zone of 5-9 m/s, effectively inhibiting dust diffusion. The exhaust section maintains a wind speed of 4-7 m/s, with streamlined convergence enhancing suction efficiency, thereby limiting the spread of blasting dust within a 15-meter radius. This system significantly reduces the risk of dust accumulation and proves more suitable for dust suppression in long-distance roadway development.
