论文中文摘要: |
我国的煤矿安全生产形势虽有好转,但是煤矿生产事故仍然时有发生。由于煤矿安全生产事故80%以上是由于矿工不安全行为引起的,所以,管控矿工的不安全行为,是避免煤矿企业人员伤亡和财产损失的重要途径,对提高煤矿企业的整体安全水平具有现实意义。因此,本文在现场调研与访谈的基础上,结合矿工风险感知水平测量量表与安全行为能力测量实验,对矿工的风险感知水平与其不安全行为之间的关系进行了研究。
首先,运用文献综述法,提取出风险感知的6个构面,在此基础上选取陕西某煤炭集团公司下属3个煤矿的12名班组长进行关键事件访谈,对访谈结果进行统计,超过50%的访谈对象对这6个风险感知构面表示认可,验证了其对于煤矿企业员工的适用性。以此为基础,编制了矿工风险感知水平测量量表,并对150名煤矿企业员工进行测量,应用SPSS对量表采集到的数据进行信度和效度分析,验证了量表具有较高的可靠性。
其次,设计构建风险感知对安全行为能力影响的眼动实验,选取两个煤矿企业生产中常见的不安全行为,闯红灯与不进行敲帮问顶,作为模拟场景,将不安全行为区域画为风险区域,选取被试在实验中到达风险区域的首注视点到达时间,注视点持续时间,注视点个数三个指标,用以衡量被试对于风险信息的注意情况,以此反映被试的安全行为能力。采用组间对比方式,对不同风险感知水平的被试的实验结果,进行可视化分析与原始数据分析。发现风险感知水平与矿工对于风险信息的注意力分配结果有显著相关性,并且发现风险感知水平较高的被试,对于风险信息的注意力能力较强,说明风险感知水平高的被试其安全行为能力越强。在此基础上,进一步设计了针对矿工风险感知水平与安全行为能力关系研究的实验,对137名煤矿企业员工进行实验测量,发现风险感知水平越高的矿工其注意力持续时间越久,抗干扰能力越高。得出的结论是,矿工风险感知水平越高其注意力集中能力越强,更容易注意到风险信息,不安全行为发生的可能性越低。
最后,在以上研究的基础上,从组织管理与矿工两个层面上提出了提高风险感知水平的对策建议,并且在对实验结果分析的基础上,提出了通过提高矿工注意力水平,以提高矿工安全行为能力的具体措施。

论文外文摘要: |
Our coal mine production safety situation improved somewhat, but there is a large gap between the international averages compared. Since more than 80% of the coal mine production safety accidents are caused by unsafe behavior miners, from the perspective of controlling the behavior of the miners were unsafe coal mining enterprises to reduce casualties and property losses, and protect critical production safety. Therefore, this thesis studies the relationship between the level of the miners’ risk perception and their unsafe behaviors, on the basis of research and interview.
Firstly, applying literature study and extracting six dimensions of risk perception to elect the group leaders of 12 large state-owned coal mines to have a critical interview on the basis of that. Verify the configuration of these six risk perception of employees in the coal face of the applicable resistance, thus preparing the mine employees perceived level of risk scale coal mining enterprises and 150 employees distributed verify the reliability and validity of the questionnaire.
Secondly, to design the eye movement data, elect some usual unsafe behaviors of the two coal mines, such as breaking the red light and wall tapping and roof sounding as the simulation scenarios. Drawing for the unsafe behavior risk areas, of different levels of risk perception notes to the point of its subjects arrival time risk areas, notes point duration, number of notes and other data point to reflect the risk of information being tried for the attention capacity. The experimental results were analyzed for visualization and data analysis, finding that the level of risk perception and attention miners were significantly correlated, and finding that higher levels of perceived risk were tested for the ability to focus stronger risk information. On this basis, further design of the experimental studies of miners risk perception levels and the ability to focus on the relationship of the 137 large state-owned coal mining enterprises employees experimental measurements, found that the higher the level of risk perception miners about their long attention span, the higher anti-interference ability it is. It is concluded that the higher the level of risk perception miner concentrate on, the stronger they more likely notice the risk of information to avoid unsafe behavior.
Finally, based on the results of the study, from the two aspects of organizational management and the miners proposed to improve the level of risk perception suggestions, and based on the analysis of the second experiment, put forward specific measures to improve miners’ attention.
