2、和主要風(fēng)機(jī)性能鑒定的結(jié)果進(jìn)行分析,制定了優(yōu)化方案,主要措施包括:巷道降阻、合理配風(fēng)、后期通風(fēng)系統(tǒng)確定,利用VNT軟件數(shù)據(jù)解網(wǎng),驗(yàn)證了優(yōu)化方案的效果。并針對(duì)礦井后期的生產(chǎn)部署,制定了二水平的通風(fēng)系統(tǒng)方案,通過評(píng)價(jià)對(duì)比,選擇了合理方案。結(jié)果表明,對(duì)東翼回風(fēng)大巷斷面擴(kuò)修可有效降低礦井通風(fēng)阻力,大大降低風(fēng)機(jī)能耗,通風(fēng)系統(tǒng)穩(wěn)定、可靠,為礦井安全生產(chǎn)提供了保障。關(guān)鍵詞:礦井;通風(fēng)系統(tǒng);優(yōu)化方案;改造中圖分類號(hào):TD728文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1004~4051(2015)08—0105~05Optimizationforvent
