摘要:

为进一步提升我国粉尘防爆工作的针对性和有效性,统计2005—2020年国内67起粉尘爆炸事故案例发生的年份、地区、粉尘类型和企业规模,分析事故原因、环节和后果,并提出工作建议。结果表明:金属、煤炭、粮食和木材粉尘是导致爆炸最主要的4种粉尘类型,大中型企业发生的粉尘爆炸事故数量较少,但后果较为严重;导致粉尘爆炸事故的主要原因为人员违规操作、通风除尘设施设置不完善、设备设施安全设计存在缺陷、其他安全事故导致;金属抛光车间、除尘系统、地下矿井和粉尘干燥塔等是重点预防粉尘爆炸的生产场所;粉尘爆炸事故导致死亡10人以上的粉尘类型为煤尘、金属粉尘和粮食粉尘。

Abstract:

In order to further improve pertinence and effectiveness of dust explosion prevention in China, statistical researches on 67 dust explosion accidents from 2005 to 2020 were carried out, including year, region, dust type and enterprise scale, and their causes, workplaces and consequences were also studied before some preventive suggestions were put forward. The results show that metal, coal, grain and wood dust are the four main dust types that cause explosion. Number of such accidents in large and medium-sized enterprises is small, but the consequences are much more severe than those in small and micro-sized ones. And major causes of the 67 dust explosion accidents are individuals' illegal operation, imperfect ventilation and dust removal facilities, defects in safety design of equipment and facilities, and other safety accidents. In terms of sites, metal polishing workshop, dust removal system, underground mine and dust drying tower should be paid more attention to prevent explosion. Moreover, the dust types causing more than 10 deaths in explosion accidents are namely coal, metal and grain.

Key words: dust explosion accident, dust type, cause of accident, accident consequence, statistical analysis
