针对贵州省六盘水矿区实际降尘情况，在喷雾的雾化及湿式除尘理论的基础上，利用回风巷断面突然变化降尘方法，根据六盘水矿区响水煤矿 W134综采工作面回风巷的具体特点，剖析构建液滴捕尘效率和喷雾除尘效率的计算模型，并在不同水压下运用Matlab7?0仿真，得到在不同喷嘴孔径条件下的喷雾除尘效率曲线，设计了回风巷断面突然扩大段水幕喷雾系统。
針對貴州省六盤水礦區實際降塵情況，在噴霧的霧化及濕式除塵理論的基礎上，利用迴風巷斷麵突然變化降塵方法，根據六盤水礦區響水煤礦 W134綜採工作麵迴風巷的具體特點，剖析構建液滴捕塵效率和噴霧除塵效率的計算模型，併在不同水壓下運用Matlab7?0倣真，得到在不同噴嘴孔徑條件下的噴霧除塵效率麯線，設計瞭迴風巷斷麵突然擴大段水幕噴霧繫統。

With reference to the actual dust situation in Liupanshui Mine,the method of airG return way sudden changing was used based upon the theories of spray atomization and wet dust removal?According to the specific characteristics in the W134 airGreturn way of fullyGmechanized coal face of Xiangshui Mine in Liupanshui,Guizhou Province,the authors analyzed on building efficiency of a single droplet catching and calculation model of spray dust removal efficiency?Meanwhile Matlab7?0 software has been used to simulate spray efficiency curve under different water pressures and designed the spray system of the air flow clean water curtain in airGreturn way sudden expansion section.
