防逆流防突风门在突出矿井的应用

Anti-reflux damper used in prominent mines

针对煤与瓦斯突出矿井,除采取必要的防突措施外,还需增加一定的防突设施。防突风门在普通风门的基础上增加了调节风窗、风筒及输送机防逆流装置,实现了风量调节及防止煤与瓦斯逆流的功能,该新型防突风门结构简单,安装方便,制作成本低,在煤与瓦斯突出矿井有很好的适应性,对矿井安全生产具有重要的工程实践意义。

In the case of coal and gas outburst mine, the necessary precautions should be added in addition to the necessary precautions.Outburst prevention damper in ordinary damper increased on the basis of regulating the wind window, ram and writers reflux device, realizesthe function of air regulation and prevention of coal and gas flow, the new type of outburst prevention damper has simple structure, convenientinstallation, low production cost, in the coal and gas outburst mine has very good adaptability, the mine production safety have importantengineering practical significance.
