摘要
通过新桥硫铁矿 2 30m中段 6次自燃火灾事故调查和矿岩自燃倾向性以及现场堆矿实验研究 ,系统阐述了硫化矿石氧化自热到自燃整个过程的特征规律 ,并针对火灾提出了一系列防灭火技术措施 ,特别指出了硫化矿石自燃初期征兆的识别方法 ,对硫化矿山火灾预防和综合治理有重要指导意义。
Based on investigating the fire cases on-230m level inXinqiao Pyrite Mine and the tests of spontaneous combustion of the sulfide ores both in laboring and in field,the breeding-fire process and features of the sulfide ores from self-heating to combustion were described in detail in this paaer.Furthermore,some effective measures for controlling fire of ore dumps were summarized.The achieved conclusions are of great significance to be applied in other sulfide mines for preventing and extinguisging fire.
