In order to solve the problem of large dust concentration in a fully mechanized excavation face, the forming mechanism for the dust resistance of vortex air curtain is studied based on the phase flow theory and the characteristics of gas-dust particle two-phase flow. The mathematical model of k-ε-Θ-kp is established and used to solve the diffusion law of suction dust control via vortex air curtain. And based on the Simple algorithm with a grid, the pretreatment software Fluent is adapted to conduct the numerical simulation on the spatial distribution law of dust concentration in a fully mechanized excavation face. The simulation result shows that a lot of dust could effectively enclose in a range of 0.5m from tunneling place to the front of road header driver via vortex air curtain suction dust control. According to the simulation results and the actual conditions of working face on-site, the system of suction dust control via vortex air curtain in a fully mechanized excavation face is designed. The system is composed of pane wall of fan drum and dust-removing and cleaning device. After applying vortex air curtain suction dust control system to a fully mechanized excavation face, the average sedimentation rate of the whole dust and respirable dust are as high as 94.4% and 93.7%, respectively, which effectively reduces the dust concentrations on work-site locations face in a fully mechanized excavation face, and achieves a good dust fall effect. The promising development prospect of vortex air curtain suction dust control system for solving the problem of the large dust concentration in a fully mechanized excavation face are adequately

articleAbstract=涡流风幕抽吸控尘系统可有效控制气载粉尘的扩散。为了解决综掘工作面粉尘浓度过大的难题，分析了涡流风幕的形成机制，并根据气固两相流理论和气体-粉尘颗粒两相流动的特性，建立求解综掘工作面涡流风幕抽吸控尘流场粉尘扩散规律的k-ε-Θ-kp数学模型；采用基于同位网格的Simple算法，利用Fluent软件对综掘工作面粉尘浓度的空间分布规律进行了数值模拟，模拟结果显示，涡流风幕抽吸控尘流场能有效地将粉尘封闭在掘进头至掘进机司机前方0.5m的空间内。根据模拟结果和工作面现场的实际条件，设计了由附壁风筒和抽尘净化装置构成的综掘工作面涡流风幕抽吸控尘系统，该系统在综掘工作面应用后，有效地降低了工作面现场的粉尘浓度。,
