摘要:
为探究连采双巷道掘进过程中风流-粉尘耦合运移规律，采用理论分析、CFD数值模拟与现场实测相结合的方法，构建包含双巷道、连采机等设备的1∶1全尺寸模型，开展多物理场耦合仿真。研究结果表明：风流场呈现附壁射流、锥形流场、过渡流场、平稳流场4阶段分区特征，平稳风流区风速稳定在1 m/s；掘进巷道粉尘质量浓度（最高893.1 mg/m3）显著高于支护巷道，连巷因风流能量低易导致粉尘积聚；通过建立粉尘扩散距离拟合模型，揭示了设备阻挡（四次项）、重力沉降（二次项）与风流输送的协同作用机制。研究结果可为智能通风系统开发及煤矿职业健康防护提供理论参考。
Abstract:
In order to explore the airflow-dust coupled migration laws during dual-roadway excavation in continuous mining operations,a methodology combining theoretical analysis,CFD numerical simulation,and on-site measurement was adopted.A 1∶1 full-scale model incorporating the dual roadways,the continuous-miner and related equipment was constructed to perform multi-physics coupling simulations.The results indicate that the airflow field exhibits a four-stage zonal characteristic:wall-attached jet,conical airflow field,transitional airflow field,and stable airflow field,with the wind speed in the stable airflow region remaining at 1 m/s.The dust mass concentration in the excavation roadway (peaking at 893.1 mg/m3) is significantly higher than that in the support roadway,and the connecting roadway is prone to dust accumulation due to low airflow energy.By establishing a fitting model for dust diffusion distance,the synergistic mechanism of equipment blockage (quartic term),gravitational settlement (quadratic term),and airflow transport was revealed.The findings can provide a theoretical reference for the development of intelligent ventilation systems and occupational health protection in coal mines.
