长距离局部通风技术探究

Research on Long-distance Local Ventilation Technology

长距离巷道作为井下大规模生产中常见的巷道形式,确保其通风安全意义重大。针对长距离局部通风技术开展探究,结合具体工程实际,在分析原长距离局部通风不足的基础上,提出施工通风钻孔是实现长距离巷道全负压通风的方式,在确保通风安全的同时降低了通风能耗,提升了作业综合效益。

Long-distance roadway is a common roadway form in large-scale underground production,it is of great significance to ensure its ventilation safety.This paper explored the long-distance local ventilation technology.Combined with specific engineer-ing practice,on the basis of analyzing the shortage of original long-distance local ventilation,it put forward that construction ventilation drilling was a way to realize full negative pressure ventilation of long-distance roadway,which could ensure ventilation safety,reduce ventilation energy consumption and improve comprehensive operation benefits.
