【摘要】：对煤矿运输事故,人们往往关注的是个体人的不安全行为或失误、车辆的不安全状态等表面直接原因,而忽视其背后的原因—第三类危险源。本文关注第三类危险源对煤矿运输险兆事件的影响及作用机制。任何事故发生前都有征兆,研究险兆事件的辨识和预控是理清事故机理、有效控制煤矿运输事故的重要手段。本文从组织因素角度寻求不安全行为管控的对策,开展第三类危险源对煤矿运输险兆事件的影响研究,从而减少人员不安全行为,以期提升煤矿运输安全管理水平。首先,本文首先对煤矿运输险兆事件相关基础理论进行了分析,对煤矿运输险兆事件概念进行了辨析,运用文献综述法分析归纳出煤矿运输事故第三类危险源、个体人失误以及煤矿运输险兆事件的影响因素。其次,在文献综述的基础上,编制了煤矿运输事故第三类危险源、个体人失误与煤矿运输险兆事件关系调查问卷。通过SPSS21.0对回收的调查问卷进行了信、效度分析以及探索性因子分析。结果表明,问卷的信、效度良好,煤矿运输事故第三类危险源包含安全规章制度失效、安全文化氛围不良、安全使命感缺乏、安全沟通失效四个因子,个体人失误包含心理素质、知识素养、身体状态及遗传因素四个因子,煤矿运输险兆事件包含险兆事件认知、发现和上报三个因子。再次,依据探索性因子分析结果,构建了第三类危险源与煤矿运输险兆事件关系结构方程模型,在调查问卷的基础上,采用AMOS7.0软件对模型进行了路径分析,结果表明,模型中的拟合指标均在可接受范围内,数据资料与模型拟合较好,验证了提出的研究假设。煤矿运输第三类危险源的各维度与险兆事件呈正相关,且通过个体人失误这一中介变量影响煤矿运输险兆事件的发生。最后,从第三类危险源、个体人失误等角度提出了煤矿运输险兆事件的预防对策。本研究有利于煤矿从第三类危险源组织因素角度做好煤矿运输险兆事件管理,为煤矿安全管理提供了新的思路和参考。
[Abstract]:For coal mine transportation accidents, people often pay attention to the direct causes of the unsafe behavior or mistakes of individuals, the unsafe state of vehicles, and so on. In this paper, we focus on the influence of the third type of hazard on coal mine transportation hazard and its mechanism of action. There are signs before any accident. It is necessary to study the identification and pre-control of risk precursor event to clarify the mechanism of the accident. This paper looks for countermeasures of unsafe behavior control from the angle of organization factor, and studies the influence of the third kind of dangerous source on coal mine transportation accident, so as to reduce the unsafe behavior of personnel. First of all, this paper analyzes the related basic theory of coal mine transportation danger, and analyzes the concept of coal mine transportation insurance. Based on the literature review method, the influence factors of the third kind of dangerous source, individual human error and coal mine transportation risk precursor event are analyzed and concluded. Secondly, on the basis of literature review, the third kind of dangerous source of coal mine transportation accident is worked out. The reliability, validity and exploratory factor analysis of the collected questionnaire were analyzed by SPSS21.0. The results showed that the reliability and validity of the questionnaire were good. The third kind of dangerous source of coal mine transportation accident includes the failure of safety rules and regulations, the bad atmosphere of safety culture, the lack of safety sense of mission, the failure of safety communication, the individual error includes psychological quality, knowledge accomplishment, There are four factors of physical condition and genetic factors, and coal mine transportation hazard event includes three factors: cognition, discovery and reporting. Thirdly, according to the result of exploratory factor analysis, The structural equation model of the relationship between the third type of dangerous source and the dangerous event of coal mine transportation risk is constructed. On the basis of the questionnaire, the path analysis of the model is carried out by using AMOS7.0 software. The results show that the fitting indexes in the model are all within the acceptable range. The data fit well with the model, which verifies the hypothesis that the dimensions of the third type of coal mine transportation hazard are positively correlated with the dangerous events. And through individual human error as an intermediary variable to influence the occurrence of coal mine transportation risk precursor events. Finally, from the third category of risk sources, This study is beneficial to the management of coal mine transportation risk from the perspective of the third kind of dangerous source organization factor, and provides a new way of thinking and reference for coal mine safety management.
