摘　　要：为了防治煤矿易自燃煤层综放工作面采空区自然发火隐患,在采煤工作面进回风隅角设置挡风帘并垒砌实体挡风墙进而控制并减少向采空区漏风是一项极为有效的防灭火措施。对于大采深、易自燃矿井,在进回风隅角采用预制充填袋代替垒砌实体墙进行封堵漏风的新工艺,堵漏风效果明显,施工安全快捷、效率高。In order to prevent and control the hidden danger of spontaneous combustion in the goaf of fully mechanized top coal caving face in easy spontaneous combustion coal seam,it is a very effective fire prevention and extinguishing measure to set up a wind curtain at the corner of the inlet and return air of the coal face and build a solid wind retaining wall to control and reduce the air leakage to the goaf.For the mine with large mining depth and easy spontaneous combustion,the new technology of plugging air leakage by using prefabricated filling bag instead of barrier solid wall at the inlet and return air corner has obvious air leakage effect,safe and fast construction and high efficiency.
