金属硫化矿尘爆炸研究进展

金属硫化矿在工业上广泛应用的同时，在开采、储运等过程中带来了粉尘爆炸的危险，这是由于其包含的硫元素、铁元素化学性质活泼导致的。综述了近年来金属硫化矿尘爆炸的研究进展；具体分析了硫含量、铁含量、粉尘粒径与形状、粉尘质量浓度等因素对爆炸参数的影响，并与硫尘、煤尘爆炸做了对比；利用系统安全学理论，基于本质安全角度，从人（作业人员）-机（金属硫化矿尘）-环境（作业环境）3个方面阐述了预防与控制金属硫化矿尘爆炸的技术要点，并提出了磁黄铁矿掺杂影响、热力学、动力学模型等潜在的金属硫化矿尘爆炸研究方向。金属硫化矿尘爆炸独特的性质将使其成为新的研究热点，得到更深入的研究和应用。

Study Progress of Metal Sulfide Ores Dust Explosion

Metal sulfide ores are widely used in industry， at the same time， it brings the danger of dust explosion in the process of mining， storage and transportation，because of the active chemical properties of iron and sulfur elements. The study progress of metal sulfide ores dust explosion in recent years was reviewed. The effects of sulfur content， iron content， particle size and shape， mass concentration and other factors on explosion parameters of metal sulfide ores dust were specifically analyzed， and compared with that of sulfur dust explosion and coal dust explosion. According to the system security theory， and based on the intrinsic safety， the technical points of preventing and controlling explosion of metal sulfide ores dust were expounded from three aspects: human （operator）-machine （metal sulfide ores dust）-environment （working environment）. Furthermore， the potential research directions of metal sulfide ores dust explosion， such as the influence of pyrrhotite doping， thermodynamics and kinetic model， were put forward. The unique properties of explosion of metal sulfide ores dust will make it a new research hotspot and will be further studied and applied.
