高负压矿井手控气动风门开关的设计

Switch Design of Hand Controlled Pneumatic Air Door in High Negative Pressure Mine

泉店煤矿属中央并列式通风,负压较大,进回风巷之间的风门难以开启,给安全生产带来较大隐患。以泉店矿东翼充电硐室回风联巷风门为例,阐述了所需手控气动式风门开关的选型计算,提出了风门开关装置的设计方案并应用于实际,效果良好,促进了矿井的安全生产。

Ventilation way of Quandian Mine was central parallel ventilation,because of high negative pressure,air door was hard to open,which was a great hidden danger to safety production.Taking air door of charging chamber in return airway in west wing of Quandian Mine as example,it introduced the selection calculation of pneumatic hand controlling switch of air door.The design of switch on air door device was proposed and was applied into practice,which gained good effects.Safety production had been greatly improved,too.
