【摘要】：瓦斯爆炸事故是煤矿最为严重的灾害之一,每次瓦斯爆炸事故发生前,都会出现诸多没有造成严重后果的小事件,这些小事件被称为煤矿瓦斯爆炸险兆事件。因此,加强对险兆事件的干预研究,就会将事故消灭于萌芽状态,这对于防治煤矿瓦斯爆炸事故具有重要意义。本研究首先在瓦斯爆炸险兆事件理论概述的基础上,提出煤矿瓦斯爆炸险兆事件的定义。并据此通过文献综述与现场访谈,从瓦斯爆炸的三个条件入手,初步提出22个煤矿瓦斯爆炸险兆事件的影响因素;其次通过问卷调查对所提取的影响因素进行实证,采用SPSS19.0对回收的问卷进行项目分析与探索性因子分析,提取出4个公因子与21个子因子,形成煤矿瓦斯爆炸险兆事件的致因因素。运用逻辑推理的方法从致因因素中提取干预对策,并对干预对策的影响关系进行分析,形成干预系统。依据提出的干预系统从个体行为安全、系统设备安全、环境条件安全、组织管理安全四个方面构建了煤矿瓦斯爆炸险兆事件SD组合干预模型,对组合干预模型中的回路进行了分析,提取了组合干预对策;最后运用系统动力学的方法对组合干预SD模型进行了仿真模拟,并对组合干预对策的干预效果进行了对比分析,发现组合干预对策有效,并且不同的组合干预对策干预效果不同。在此基础上,设计了组合干预对策实施流程及方案。本研究针对煤矿瓦斯爆炸险兆事件,对其组合干预对策进行研究,从而将事故的预控转化为险兆事件的预控,有利于事故预防关口前移。险兆事件的组合干预将会有效控制煤矿瓦斯爆炸事故的发生,为提高煤矿安全管理水平提供借鉴和参考。
[Abstract]:The gas explosion accident is one of the most serious disasters in coal mine. Before every gas explosion accident, there will be many minor events without serious consequences. These minor incidents are called coal mine gas explosion hazard events. Therefore, it is of great significance to strengthen the intervention research on the dangerous and precursor events, which will nip the accident in the bud state, which is of great significance to prevent and cure the coal mine gas explosion accident. Based on the summary of the theory of gas explosion hazard, the definition of coal mine gas explosion hazard event is put forward in this paper. Based on the literature review and field interviews, the influencing factors of 22 coal mine gas explosion hazard events are preliminarily put forward from the three conditions of gas explosion. Secondly, the influence factors were tested by questionnaire, and the item analysis and exploratory factor analysis were carried out by SPSS19.0, and 4 common factors and 21 subfactors were extracted. Formation of coal mine gas explosion risk factors. The method of logical reasoning is used to extract the intervention countermeasures from the cause factors and analyze the influence relationship of the intervention countermeasures to form the intervention system. According to the proposed intervention system, a combined SD intervention model of coal mine gas explosion hazard events was constructed from four aspects: individual behavior safety, system equipment safety, environmental safety, and organization and management safety. The loop in the combined intervention model is analyzed and the combined intervention countermeasures are extracted. Finally, the SD model of combined intervention is simulated by the method of system dynamics, and the intervention effect of combined intervention is compared and analyzed, and it is found that the combined intervention strategy is effective. And the intervention effect of different combination intervention countermeasure is different. On this basis, the implementation process and scheme of combined intervention countermeasures are designed. In this study, the combined intervention countermeasures were studied for the coal mine gas explosion hazard event, so that the pre-control of the accident was transformed into the pre-control of the dangerous and precursor event, which was conducive to the advance of the accident prevention gate. The combined intervention of dangerous and dangerous events will effectively control the occurrence of coal mine gas explosion accidents and provide reference and reference for improving the level of coal mine safety management.
