摘　　要：掘锚一体快速掘进工作面较传统掘进方式产尘量大,产尘规律不明。基于此,本研究建立了掘锚一体快速掘进工作面,通过数值模拟研究了GMJ4260掘锚机作业下的多尘源风流粉尘污染规律。结果表明:当风流撞击在综掘面迎头岩壁后,动量急剧减小,风速降低至2 m/s左右,在风筒出风口附近粉尘浓度较高,可达1600 mg/m^(3)。研究结果可为相关作业现场提供防尘依据。The rapid excavation of the working face with integrated excavation and anchoring produces a larger amount of dust compared to traditional excavation methods,and the dust production pattern is unclear.Based on this,this study established a fast excavation working face with integrated excavation and anchoring,and studied the multi dust source airflow and dust pollution law under the operation of GMJ4260 anchor excavator through numerical simulation.The results show that when the wind collides with the head-on rock wall of the comprehensive excavation face,the momentum decreases sharply,the wind speed decreases to about 2 m/s,and the dust concentration near the air duct outlet is relatively high,reaching 1600 mg/m^(3).The research results can provide dust prevention basis for relevant work sites.
