为探讨煤矿安全标志应用的有效性,运用文献综述法,结合矿工认知安全标志的6个阶段,总结归纳出27个煤矿安全标志有效性影响因素。根据来自4个煤矿258份矿工调查问卷,利用因子分析法,建立煤矿安全标志有效性影响因素指标体系。在确定3个层次的指标权重的基础上,对各影响因素的重要度进行理论研究。结果表明:刺激性对煤矿安全标志的有效性影响力最大;心理惯性、安全标志设置位置和辅助文字对其有效性影响较为显著。优化煤矿安全标志设置,改善安全培训和管理,有助于提高安全标志的有效性。
In order to explore the validity of the application of coal mine safety signs, the author summarized the influencing factors of the effectiveness of 27 coal mine safety signs by using literature review method and combining with six stages of miners’ safety signs. According to questionnaire from 258 miners in 4 coal mines, the index system of factors affecting the effectiveness of coal mine safety signs is established by factor analysis. On the basis of determining the weight of three levels of indicators, the importance of each influencing factor is theoretically studied. The results show that irritation has the most influence on the validity of coal mine safety signs. The location of mental inertia, safety signs and auxiliary characters have a significant impact on its effectiveness. Optimizing coal mine safety signs and improving safety training and management can help improve the effectiveness of safety signs.
