摘　　要：在对现有煤矿井下孔口瓦斯防喷装置调研的基础上,对其优缺点进行分析后,设计了一种常闭式煤矿钻孔防喷装置,该防喷装置采用前封堵、后缓冲的组合结构,实验室试验表明:该结构的性能达到设计要求,具有封堵迅速、严密的优点。After investigating existing gas anti-spray devices used in collieries and analyzing their advantages and disadvantages, a new type of normal-closed drilling anti-spray device is designed, which takes the composite structure of blocking in the front and buffering in the rear. The lab tests show that this type of anti-spray device has satisfy the design requirements and can seal fast and closely.
