冶金煤气泄漏危险分析与预防对策研究 摘　要 冶金生产过程中使用大量煤气，由于人为失误、设备故障以及管理不善等原因，容易导致煤气泄漏，发生中毒、火灾或者爆炸事故。因此，有必要对冶金煤气泄漏进行危险性分析并提出预防对策。 本论文首先对冶金煤气泄露事故进行了统计和分析，然后针对易发生煤气泄漏危险的区域，编制了安全检查表，以便对煤气泄漏的危险性进行全面、系统性的分析和评价。利用事故树分析法分析了煤气泄漏事故发生的原因及方式事故的危险性，并提出了针对性措施。采用道化学火灾、爆炸危险指数评价法对存在煤气泄漏危险的典型区域进行评价，得到了火灾、爆炸事故的危险等级、危害半径和财产损失。最后，根据分析和评价的结果，提出预防冶金煤气泄露的主要技术措施和管理措施，制定出冶金煤气的安全管理要求和安全教育培训措施。 本文的研究成果将有助于指导冶金企业对冶金煤气泄漏的危险点进行有效排查，并采取针对性的预防措施，保障安全生产。 关键词：冶金煤气，泄漏，危险性分析，预防对策 The Risk Analysis and Prevention Countermeasures of Metallurgical Gas Leak Abstract With the widely production and use of metallurgical gas in industrial enterprises, the accidental leakage of the gas happens frequently in the process of production, transportation and use, which is due to lack of consciousness, poor management and other reasons. The painful consequences and bloody lessons caused by the accidents are wake-up calls. Therefore, it is necessary for metallurgical gas to carry out some hazard analysis and propose some preventive measures. This paper firstly counts up the metallurgical gas accidents and analyzes the reasons. For the region where gas leakage happens frequently, the safety check list is used to check the dangerous points according to the rules, procedures and standards. Besides, It analyzes the reasons for accidents specifically with the accident tree analysis, which can compare the system risk intuitively by the minimum cut sets. It evaluate the typical regions with the Dow Chemical fires and explosion hazard index evaluation method, and calculate the hazard radius of the accident and property damage, in order to determine the degree of the danger of each unit fire and explosion.Finally, by the quantitative and qualitative evaluation of the metallurgical gas leakage, some main technical measures and management measures were put forward to prevent the gas leakage, and formulate a metallurgical gas safety management requirements and safety education training measures. The results of this paper will contribute to metallur
