摘要
矿山应用受控循环通风技术的目的在于有效提高工作面的有效风量,进行了应用导风板提高循环区有效风量率的研究,通过研究表明:在循环横巷出风口处安设引导风流的导风板,使循环风流面向回采工作面,背向外来新鲜风流,利用风流动压方向性,使循环风流最大限度地流向工作面,达到了导风板应用的目的.
The purpose of controlled recirculation ventilation application is to effectively enhance air volume at working face. This paper focuses on applying guild plate to increase effective air volume rate in recirculation area. The research result shows that setting guild plates at recirculation connected lane air outlet may lead air volume flow to working face, and using directivity of air pressure can make air flow to working face maximum, which is helpful to improve working condition at working face.
