The most heavy flow ability of barrage swirl is controlled by fastenning device and barrage size, the most heavy discharge is more when barrage aperture is bigger, the influence of barrage position on discharge is not obvious; The pressure of the end of the shaft and fastenning device increases which aroused by barrage, and there is a restraining action to flow waving of the shaft; The barrage aperture is smaller, the increase of pressure is heavier, the influence of position to the increase of pressure is not obvious; The positive pressure of the level section in the hole between fastenning device and barrage increases obviously, the change of press along length reduces, mural press in the hydrosphere separating area of outlet of fastenning device becomes positive pressure, which is propitious to the increase of flow cavitate number in the low pressure area of the outlet of fastenning device; The influence of change of swirl cavum diameter caused by barrage to ventilating state is obvious.

阻塞旋流最大泄流能力由起旋器及阻塞体型共同控制，降低了泄洪洞的泄流量，孔径大的阻塞最大下泄流量较大，阻塞位置对泄流量的影响不明显；阻塞引起竖井及起旋器端头压力增大，对竖井部分的水流波动具有抑制作用；阻塞孔径越小，压力增加越大，位置对压力增大影响不明显；起旋器与阻塞之间水平洞段的止压力明显增加，沿程压力变化减小，起旋器出口的水气分离区壁面压力变为正压力，有利于起旋器出口低压区水流空化数的提高；阻塞引起的旋流空腔直径变化对通气状态产生明显影响。

Based on theories of multiphase fluid mechanics and mine ventilation theories,the model of drivage tunnel was established by using the method of similar experiment,the characteristics of ventilating current and gas concentration distribution in drivage tunnel were studied by the experiment,and based on the above characteristics the flow characteristics of gas transportation multiphase flow field were majorly analyzed.

基于多相流及矿井通风理论，利用相似性实验方法，搭建了煤矿掘进巷道模型，并通过模型实验获得了掘进巷道内风流流场和瓦斯浓度分布场的特征信息。结合上述两方面的特征信息重点分析了巷道内瓦斯运移多相流场的流动特性，所采用方法对于矿井通风系统及瓦斯监测系统的设计具有较强指导意义。
