调研了现阶段立井、斜井防爆门使用现状及存在问题,针对矿井防爆门在爆炸以后不能准确复位,影响矿井通风系统快速恢复的问题,提出了一种新型立井防爆盖,可在瓦斯爆炸时有效增强矿井防爆门抗冲击变形和复位能力;对斜井防爆门在冬季使用过程中存在的冷冻、本身材料过重问题进行了探讨,并给出了解决方案。
The status quo and existing problems of the explosion-proof doors in shaft and inclined shaft are investigated. In view of the problems that the explosion-proof doors in the mine can not be accurately reset after the explosion and affect the rapid recovery of mine ventilation system, a new type of shaft explosion protection cover is proposed, which can be used in gas explosion Which effectively enhances the anti-impact deformation and resetting ability of mine explosion-proof doors; discusses the problem of frozen and over-material of the explosion-proof doors in winter when they are used, and provides solutions.
