Coal mine gas explosion injury has caused mass casualties, which have resulted in widespread concern.
In order to prevent gas explosion injury in coal mine, 24Model is proposed to analyse the risk in this paper. 24Model is a human-oriented and organisation-oriented risk analysis method. Based on the 24Model, we propose a general procedure for analysing the causes of injury within the organisation.
A coal mine gas explosion case was analysed using the 24Model and the proposed analysis method, and the evolution of injury and the interaction of various causes was showed, and 6 unsafe conditions, 25 unsafe acts, 13 safety knowledge, 13 safety management systems and 13 safety cultures were obtained.
Case analysis results show that by using the 24Model and analysis method the proposed effect can help employees to clearly see the evolution and identify the causes of the injury, to better understand the logical relationship with the causes of the injury, improve the effectiveness of training and effectively prevent similar injury. The case study provides a practical procedure for injury investigation and analysis, and thus, preventive measures can be made according to the various causations at different levels.
煤矿瓦斯爆炸事故已造成大量人员伤亡，引起广泛关注。
为预防煤矿瓦斯爆炸事故，本文提出24模型对风险进行分析。24模型是一种以人为本、以组织为导向的风险分析方法。基于24模型，我们提出了一种分析组织内伤害原因的通用程序。
运用24模型及所提出的分析方法对一起煤矿瓦斯爆炸案例进行了分析，展示了伤害的演变过程以及各种原因之间的相互作用，得出了6个不安全条件、25个不安全行为、13个安全知识、13个安全管理制度和13个安全文化。
案例分析结果表明，运用24模型及所提出的分析方法，有助于员工清晰地看到伤害的演变过程，识别伤害原因，更好地理解与伤害原因的逻辑关系，提高培训效果，有效预防类似伤害。该案例研究为伤害调查与分析提供了实用程序，从而可根据不同层面的各种因果关系制定预防措施。
