摘要

依据某大型金属矿山井下机械化盘区通风的实际情况,在矿用空气幕替代辅扇的应用研究成功的基础上,现场开展硐室型风机机站的应用试验,对比研究的结果表明:硐室型风机机站可以有效替代传统风机机站,能在难以设置有风墙风机机站的巷道中安装运行,实现各盘区进风巷道风流的合理分配;硐室型风机机站能有效引射风流,控制风流短路,增加中段进风量达27.3 m3/s,强化中段通风网络的排烟排尘效果,有利于保护工人的身体健康、提高矿井的有效风量率和促进矿井风流的有序流动;硐室型风机机站可以由单台风机或多台风机构成,安装在巷道侧壁的硐室内,增强多级机站通风方法的可靠性和适应性。
        Based on the real underground mechanized panel cutting of some large metal mine,the application test of fan station in cavern with the successful substitute of air curtain for auxiliary fan was studied.The results show that the fan station in cavern is an effectively substitute for the traditional fan station in realizing the reasonable fan flow distribution in inlet air tunnel of every panel cutting,where the fan station with wind wall is hard to be installed.The fan station in cavern can effective induce the flow direction,control the flow short-circuit,and increase inlet air volume in middle tunnel to 27.3 m3/s.This increase could enhance the effect of smoke and dust exhaust in the section ventilation network,which is beneficial to protect the workers’ health,improve the effective air volume rate and promote the orderly flow of mine airflow.The fan station in cavern can be constituted by single fan or multiple fans,and can be installed in the side wall of the tunnel.This enhances the reliability and flexibility of the multi-stage fan station.
