我国煤矿自50年代初期就开始应用灌浆法预防和消灭矿井火灾,至今已有30多年历史,现在绝大多数矿井还在继续沿用。不少具有内因火灾危险的硫化矿山也采用了灌浆防灭火方法。实践证明,灌浆法防灭火技术在矿井安全生产中发挥了巨大的作用。通常使用黄泥灌浆,有些矿区黄泥来源不足,寻找了一些泥浆材料的代用品,如四川芙蓉矿用破碎的页岩;开滦赵各庄矿用电厂 Since the early 1950s, China’s coal mines have started to apply the grouting method to prevent and extinguish mine fires. It has been more than 30 years old. At present, the vast majority of mines are still in use. Many sulfide mines with internal fire hazards also use grouting fire-fighting methods. Practice has proved that grouting fire prevention and control technology in mine safety has played a huge role. Yellow mud grouting is often used, and some mines have insufficient sources of yellow mud, looking for substitutes for mud materials such as broken shale from Sichuan Furong Mine; Kailuan Zhaogouzhuang Mine Power Plant
