【摘要】：在我国各类煤矿事故中，顶板事故发生的次数与死亡总人数一直居高不下，是煤矿安全生产一重大隐患，每起顶板事故都造成惨重人员伤亡和巨大经济损失。如何有效地辨识、控制顶板事故致因是我们当前面临的一大课题。本文通过对2006年至2012年7月发生的104起中国煤矿顶板事故的统计分析，研究归纳出四个层面的20个煤矿顶板事故致因因素，并运用系统分析的方法，确定顶板事故致因因素之间的内在关系，为构建煤矿顶板事故致因模型提供了基础。基于解释结构模型理论，构建煤矿顶板事故致因7层多级递阶系统。清晰揭示了煤矿顶板事故发生的表层原因、中间层原因以及深层根本原因。分析表明深层根本原因主要包括监察体系不完善、内部管理机制不完善。同时运用AHP法计算各致因因素的权重，分析各致因因素对顶板事故的影响程度大小，其结果显示个体行为和管理因素所占的比重高达85.34%。基于煤矿顶板事故致因ISM模型，在确定各个致因因素权重的前提下，引入模糊综合评价方法，以山西某煤矿为例，，对该矿顶板事故发生的风险进行模糊综合评判，确定该煤矿顶板事故发生趋势。最后，在对煤矿顶板事故致因ISM模型研究基础上，从提高支护技术水平、加大对职工培训教育力度、建立健全内部管理机制、完善监督监管体系四个方面提出了预防煤矿顶板事故对策建议。
[Abstract]:In all kinds of coal mine accidents in our country, the number of roof accidents and the total number of deaths have been high all the time, which is a major hidden danger in coal mine safety production. Every roof accident has caused heavy casualties and huge economic losses. How to effectively identify and control the causes of roof accidents is a major issue we are facing. Based on the statistical analysis of 104 roof accidents in coal mines in China from 2006 to July 2012, the causes of 20 roof accidents in coal mines at four levels are studied and summarized, and the method of systematic analysis is used in this paper. The internal relationship between the cause factors of roof accident is determined, which provides the basis for constructing the model of roof accident cause in coal mine. Based on the theory of explanatory structure model, a 7-layer multi-level hierarchical system for roof accidents in coal mines is constructed. It clearly reveals the surface layer reason, the middle layer cause and the deep root cause of coal mine roof accident. The analysis shows that the underlying causes include imperfect supervision system and imperfect internal management mechanism. At the same time, the weight of each factor is calculated by using AHP method, and the influence degree of each factor on roof accident is analyzed. The result shows that the proportion of individual behavior and management factors is as high as 85.34. Based on the ISM model of roof accident in coal mine, the fuzzy comprehensive evaluation method is introduced under the premise of determining the weight of each factor. Taking a coal mine in Shanxi as an example, the risk of roof accident in this mine is evaluated by fuzzy comprehensive evaluation. Determine the coal mine roof accident trend. Finally, on the basis of the research on ISM model of coal mine roof accidents, from the aspects of improving the level of supporting technology, increasing the training and education of staff and workers, establishing and perfecting the internal management mechanism, The countermeasures and suggestions for preventing roof accidents in coal mines are put forward in four aspects of perfecting supervision and supervision system.
