基于眼动试验的煤矿禁止类安全标识位置有效性研究

安全标识作为一种安全管理手段已得到普遍应用,但在煤炭企业实际应用中并未完全发挥其应有作用。为了研究煤矿禁止类安全标识放置的有效性,首先,通过构建眼动试验平台进行试验,选取煤矿井下皮带运输、井口等图片作为模拟场景;其次,将场景中安全标识区域作为兴趣区域,采集不同被试的注视点个数、首次进入时间等数据;最后,运用SPSS 20.0软件和统计方法分析试验采集的数据。结果表明,安全标识有效的设置位置为编号(2)(上中)和编号(5)(正中)。

On the effectiveness of the coal mine safety signboards for prohibition based on the eye-movement testing apparatus

The paper is aimed at improving the layout of the safety signs in the coal mines so as for the sign boards to play their due roles in the practical application.However,as a matter of fact,there still exist some serious problems in this way,which should account for low effectiveness of the safety signs and for some of the coal mine accidents.Therefore,to solve the said problems and improve the safety level of the coal mine prodcution,the present paper intends to make a discussion on how to choose the most available positions for putting up the prohibition sign boards in the coal mines.To begin with,the author has done an eye movement experiment by constructing the eye-movement experimental platform by choosing the underground belt transportation as well as the mine opening and other typical scenes as the stimulating scenes according to the commonest scenes in the daily producing activities in the mine.Secondly,more attention has to be paid to the choice of the places for the safety-warning signs.And,then,we have chosen an eye tracker to make the recordings and collect the experimental data from the different participants automatically with the help of the said recording apparatus,such as the time length of the first fixation,the first fixation duration,and the first fixation accounting results and the other eye-movement data.And,finally,we have made an analysis of the experimental data by using a software known as SPSS 20.0 and some other statistical methods.The results of our study indicate that the positions of No.5(the center) and No.2(the top center) tend to attract the greatest attention of the different participants whereas the resuhs of the experimental tracing show that the position of No.2 (top center) and No.5 (center) should be put onto the most effective setting positions.Therefore,it can be concluded that our study and experiment can be regarded to a certain extent as being helpful for regular and idealistic setting up and application of the safety signboards of prohibition in the coal mines.Furthermore,it can further improve the safety management level of the coal mine production by more effective placement of such safety signboards therein.
