【摘要】：随着煤矿机械化水平的提高,煤矿生产效率在提高的同时也伴随着机械作业险兆事件的发生。作为煤矿开采的重要设备,采煤机作业险兆事件的发生不但影响着设备的安全状态,还影响着一线操作员工的生理状态,且往往是引发采煤机事故的前兆事件。预防采煤机作业险兆事件的发生,是控制煤矿事故,实现煤矿安全生产的重要举措。本文的主要内容包括以下几个方面。首先,通过文献综述对险兆事件的基础理论和险兆事件的管理理论进行了分析。对采煤机作业险兆事件进行了定义;辨析了采煤机作业险兆事件和危险源及事故隐患的关系;区分了采煤机作业险兆事件与采煤机作业事故的不同点;根据采煤机作业险兆事件可能引发的后果,对其进行了分类;结合事故致因理论构建了采煤机作业险兆事件的致因概念模型。其次,在理论分析和实践调研的基础上,提取了采煤机作业险兆事件影响因素,并编制了采煤机作业险兆事件的调查问卷,用SPSS19.0软件对回收的问卷进行统计分析。结果显示,整体问卷的效度良好,采煤机作业险兆事件的影响因素包括人的失误,采煤机“带病”作业,作业空间和安全管理水平等19个致因因素。然后,分析了各影响因素间的相互关系,构建出采煤机作业险兆事件的因果关系模型,基于此构建了采煤机作业险兆事件的解释结构模型,并对解释结构模型进行分析,建立了采煤机作业险兆事件致因因素的三层递阶结构模型。分析结果显示,管理失误等是引起采煤机作业险兆事件的深层原因,人、机、环是引起采煤机作业险兆事件的表层和中层原因。最后,运用系统动力学原理建立采煤机作业险兆事件三个致因层的组合干预SD模型,并运用Venism软件对模型进行仿真模拟,在验证干预有效的基础上,设计出采煤机作业险兆事件的组合干预对策的实施流程,以及三个致因层的干预对策。
[Abstract]:With the improvement of the level of mechanization of coal mine, the production efficiency of coal mine is improved and accompanied by the occurrence of dangerous events of mechanical operation. As an important equipment in coal mining, The occurrence of coal mining machine operation danger event not only affects the safety state of the equipment, but also affects the physiological state of the front-line operator, and is often the precursor event that causes the shearer accident. It is an important measure to control coal mine accidents and realize coal mine safety production. The main contents of this paper include the following aspects. First of all, Based on the literature review, the basic theory and management theory of dangerous omen events are analyzed, and the definition of dangerous omen events in shearer operation is given, and the relationship between the dangerous omen events and dangerous sources and hidden dangers of coal mining machines is analyzed. It distinguishes the difference between shearer operation danger event and shearer operation accident, and classifies it according to the possible consequence of shearer operation danger event. Based on the theory of accident cause, the paper constructs a conceptual model of the cause of coal mining machine operation danger event. Secondly, on the basis of theoretical analysis and practical investigation, the influencing factors of coal mining machine operation danger event are extracted. The questionnaire was compiled and analyzed by SPSS19.0 software. The result shows that the validity of the questionnaire is good, and the influencing factors of the dangerous event of coal mining machine include human error. There are 19 cause factors, such as the work with disease, the working space and the level of safety management, etc. Then, the relationship between the influencing factors is analyzed, and the causality model of the dangerous event in the shearer operation is constructed. Based on this, the interpretation structure model of coal mining machine operation danger event is constructed, and the explanation structure model is analyzed, and the three-level hierarchical structure model of the factor causing the coal mining machine operation danger event is established. The analysis results show that, Management errors are the deep causes of dangerous events in shearer operations. People, machines and rings are the surface and middle layer causes of dangerous events in shearer operations. Finally, Based on the principle of system dynamics, the combined intervention SD model of three dangerous events in shearer operation is established, and the model is simulated by Venism software. On the basis of verifying the effectiveness of intervention, the model is simulated and simulated. The implementation process of combined intervention countermeasures and the intervention countermeasures of three factors are designed.
