被动式隔爆水棚子是世界一些主要产煤国广为使用的隔绝煤尘爆炸的措施之一。实践证明,按要求在井下设置的被动式隔爆水棚子(下面简称“水棚子”)能抑止煤尘爆炸、限制爆炸范围,提高煤矿安全水平。但是“水棚子”并不是一种万全无缺的措施,它只能隔绝井下发生的某些煤尘爆炸,而在一些矿井条件下,其隔爆效果甚至很差。目前,国内外所采用的任何一种单一的
Passive flameproof water shed is one of the most widely used methods of coal dust explosion in some of the world's major coal producing countries. Practice has proved that the required set of passive underwater flameproof shed (hereinafter referred to as “water shed”) can restrain the explosion of coal dust, limiting the scope of the explosion and improve the safety level of coal mines. However, the “water shed” is not an all-encompassing measure. It can only isolate some coal dust explosions that occur underground, and in some mine conditions, the flameproof effect is even worse. At present, any single kind adopted at home and abroad
