甘肃省华亭煤矿坚持依靠科学技术,在同矿井自燃火灾长期斗争中,积累经验,总结出具有国内先进水平的12项综合防灭火技术措施,消除了煤炭自然发火,防治了矿井自燃火灾,创造了矿井连续13年生产原煤无死亡、9年无发火的新记录。 据统计,煤矿矿井70％以上具有自然发火现象,80％的自燃火灾发生在厚煤层中,86％的自燃火灾发生在5米以上的特厚煤层中。全世界每年烧毁损失和破坏煤炭资源数十亿吨,仅我国北方每年烧失和破坏煤炭资源2亿—3亿吨,造
Huating Coal Mine in Gansu Province has always relied on science and technology and has gained experience in the long-term struggle against spontaneous combustion in coal mines. It has summarized 12 comprehensive fire prevention and control measures with advanced domestic technologies, eliminated spontaneous combustion of coal, prevented and controlled mine spontaneous combustion and created a Mine for 13 consecutive years of production of coal without death, 9 years without a new record of ignition. According to statistics, more than 70% of coal mines have spontaneous combustion phenomena, 80% of spontaneous combustion fires occur in thick coal seams, and 86% of spontaneous combustion fires occur in thick coal seams above 5 meters. Every year, the world burns billions of tons of lost and damaged coal resources, burying and destroying 200 million to 300 million tons of coal resources each year in the north of our country
