摘　　要：针对司家营铁矿爆破粉尘大、扩散慢、滞留时间长的特点,通过分析粉尘产生原因,对水雾覆盖抑尘机理及影响因素进行研究,优化采场爆破方式方法,改善爆破抑尘效果,同时建立爆破抑尘管理体系,做到爆区抑尘全覆盖。Based on the characteristics of large amount,slow diffusion,and long retention time of blasting dust in Sijiaying Iron Ore Mine,the causes of dust generation are analyzed,the mechanism and influencing factors of water mist dust suppression are studied,and the blasting method in the mining area is optimized so as to improve the blasting dust suppression effects.At the same time,a blasting dust suppression management system is established to achieve full coverage of dust suppression in the blasting area.
