| 摘 要： | 掘进工作面压入式通风实际上是有限空间的受限贴附射流通风． 根据流体力学和射流理论， 分析了掘进通风射流产生过程及掘进工作面压入式通风风流结构． 风流从圆形风筒射入掘进工作面形成射流区和回流区． 给出了回流区平均速度、最大回流速度及射流作用距离的计算模型， 为掘进工作面合理有效通风提供了新的理论依据． |
| 关 键 词： | 掘进工作面 受限贴附射流 风流结构 回流速度 射流作用距离 |

| Abstract: | The forced ventilation in heading face is actually restrained wall attached jet ventilation in confined space. According to fluid mechanics and jet theory, the formation process of jet flow and flow field in heading face ventilation are analyzed. The air flow injected into heading face from round pipe form jet and back field. The calculation models are set up on average speed and max speed in back field and jet effect distance, new theoretical reference is provided for effective ventilation in heading face. |
| Keywords: | heading face restrained wall attached jet flow field back flow speed jet effect distance |
