【摘要】 煤矿特别重大事故发生频繁,后果往往是灾难性的,造成大量人员伤亡和巨大经济损失,社会影响非常恶劣。本项研究以1949~2008年间发生的煤矿特别重大事故为主要研究材料,采取统计分析和安全比较学等研究方法,研究煤矿特别重大事故致因机理。通过对水害和瓦斯爆炸事故资料的分析研究,不同时期煤矿特别重大事故致因并未发生太大变化,发生事故的企业的管理和技术提升有限,煤矿特别重大事故发生有其内在致因机理,不是一般事故的简单扩大化;不同灾难级别煤矿事故存在明显的事故致因差异,而且差异的事故致因是导致特别重大水害事故发生的关键原因;众多核心基本条件的缺失是导致灾难性特别重大瓦斯爆炸事故发生的根本原因。归纳总结出了煤矿特别重大事故致因机理,建立了事故模型,认为差异的事故致因是事故发生的关键原因,多种核心基本条件的缺失是事故发生的根本原因,二者共同作用使得事故发生后表现出灾难性的后果。认为核心基本条件、差异的事故致因和事故扩大因素三个方面是预防特别重大事故应关注的核心,给出了特别重大事故预防的具体措施。更多还原

【Abstract】 The extraordinary big coalmine accidents occurred frequently, and the consequences, causing heavy casualties, huge economic losses and bad social impacts, are often disastrous. This study uses the major accidents occurred in Chinese coalmines between 1949 and 2008 as the main material, and the statistical analysis and safety comparison as its research methods, to explore the causation mechanism of extraordinary big coalmine accidents. By analyzing the data of flood accidents and gas explosions, the result shows that the causes of different periods’s accidents have little changes, and the enhancement of management and technology of those coalmine occurred accidents are limited. Instead of the simple expansion of general accident, there is an internal accident-causing mechanism in extraordinary big coalmine accidents. The significant different causes are obvious in different disaster level accidents, and that the distinctive accident causes are the key reasons which lead to extraordinary big coalmine accidents. The lack of numerous basic core conditions is the root causation of the extraordinary big gas explosion accidents. The causation mechanism of extraordinary big coalmine accidents is summarized and the accident model is established. This paper shows that the differences in the accident causation are the key reason for the accidents, and the lack of a variety of basic core conditions is the root cause of the accidents. By the collective effect of the two factors, the accidents, which could be a general incidents, shows a disastrous consequences. Thus, for effective prevention of extraordinary big coalmine accidents, the basic core conditions, distinctive accident causes and factors of the accident expansion should be particularly concerned as the central issue.更多还原
