摘　　要：为满足超长距离掘进巷道通风需要,以6505运输巷掘进通风为研究对象,在对煤矿常用的局部通风技术进行分析基础上结合6505运输巷实际条件,提出采用单风机通风技术进行局部通风。采用理论分析方法确定了局部通风机风量及风压,最终确定了局部通风机及风筒参数。现场应用后,巷道掘进迎头风量达到455m~3/min、风筒百米漏风率为0.42%,可满足巷道通风需要。In order to meet the ventilation needs of long-distance tunneling roadway,taking the tunneling ventilation of 6505 transport roadway as the research object,based on the analysis of common local ventilation technologies in coal mines and combining with the actual conditions of 6505 transport roadway,this paper puts forward the adoption of single fan ventilation technology for local ventilation.The air volume and air pressure of local ventilator are determined by theoretical analysis method,and finally the parameters of local ventilator and air duct are determined.After field application,the head-on air volume of roadway drivage reaches 455m~3/min,and the air leakage rate of air duct is 0.42%,which can meet the needs of roadway ventilation.
