摘要
矿井通风是矿井安全生产的基本保障,它对随时掌握井巷风速、风量的变化情况,保证矿井的安全生产具有重要的指导意义。详细介绍了现有闭口直路式、闭口单回流式和开式三种矿用低速风洞的结构、工作原理及使用要求,分析了它们各自的优缺点,以便相关从业人员更好地了解和使用这三种风洞,以进一步提高检测水平。
Mine ventilation is the basic guarantee for mine safety production,keep attention to the variation of wind speed and air volume in mining roadway is significant to the safety of production.The structure,working principle and operational requirement of three types of the existing low speed wind tunnels for mining,i.e.,the closed circuit straight line wind tunnel,the closed circuit single return flow wind tunnel and the open circuit wind tunnel,are introduced.The advantages and disadvantages of these three types of wind tunnels are analyzed,so that the related practitioners can understand and use these three wind tunnels properly,and the detection level can be improved further.
