摘　　要：本文针对煤矿井下采空区防水密闭,在楔形防水密闭的基础上进行了改进,在新型密闭设计中采用了增加工字钢,增设缓冲墙等方式,承担水压效果较楔形防水密闭更加显著。该设计在煤矿生产中进行了实际应用,并进行了效果分析,在节约成本、构筑简单的基础上保障了煤矿生产的安全。Aiming at the waterproof and airtight problem of the goaf in coal mines,this article makes improvements on the basis of the wedge-shaped waterproof and airtight design.In the new airtight design,the addition of I-beams and the addition of buffer walls have been adopted to make it more effective in bearing water pressure than the wedge-shaped waterproof seal.The design has been practically applied in coal mine production,and the effect has been analyzed,which guarantees the safety of coal mine production on the basis of cost saving and simple construction.
