水在消防用途上具有简便、普及、经济等优点。但对于煤体含水来讲,由于水对煤炭自燃倾向的影响比较复杂,有人认为起促进作用,也有人认为起抑制作用。我省汾西局水峪矿及轩岗局的3个生产矿井,对有自燃倾向的厚煤层开采时,普遍采用了采空区注水降尘与胶结假顶的同时,也程度不同地起到降温防火作用。尤其轩岗焦家寨矿5118采区注水开采6个分层,六亩地矿自1974年
Water fire in the use of simple, popular, economical and other advantages. However, for the water content of coal, the impact of water on the spontaneous combustion of coal is rather complicated. Some people think that it will play a catalytic role and some people think that it may have an inhibitory effect. In our province, three production mines of Shuiyu Mine and Xuan Gang Bureau of Fenxi Hydropower Station, when mining thick coal seam prone to spontaneous combustion, commonly used the dust injection and cementing fake roof of goaf, meanwhile, they also cooled down to varying degrees Fireproof effect. In particular, Xuan Gang Jiaojiazhai Mine 5118 mining area water extraction 6 stratification, six acres of land mines since 1974
