煤矿瓦斯爆炸险兆事件致因模型构建

Causal Model Construction of Coal Mine Gas Explosion Near-miss Incidents

以煤矿瓦斯爆炸险兆事件为研究对象,运用文献综述与现场访谈的方法对其影响因素进行了归纳总结,并运用问卷调查的方法对这些因素的准确性进行了验证;然后运用解释结构模型对影响因素进行了分层,明确了煤矿瓦斯爆炸险兆事件的致因机理。研究结果表明:煤矿瓦斯爆炸险兆事件影响因素分为4类二级指标与20个三级指标;20个三级指标通过不同层级的作用关系,影响着煤矿瓦斯爆炸险兆事件的发生,表层因素中6个因素是影响险兆事件发生的直接原因,中层因素中11个因素是间接原因,深层因素中3个因素是根本原因。

Near-miss incidents in coal mine gas explosion were taken as research object, influence factors were summarized by theliterature review and field interviews, the accuracy of these factors was verified by questionnaire. Then, the interpretative structuralmodel was used to analyze influence factors, and the causal mechanism was clarified about near-miss incidents of coal mine gasexplosion. The results showed that influence factors of near-miss incidents were divided into four two-level indexes and twentythree-level indexes; through the interaction relationship of different levels, twenty three-level indexes impacted near-miss inci-dents of coal mine gas explosion, six factors of surface factors were the direct cause of near-miss incidents, eleven factors of mid-level factors were the indirect cause, and three factors of deep factors were the root cause.
