应急场景下矿工脑电成分特征的实验研究

为探究矿工在应急场景下的脑电成分变化规律,研究通过脑电实验的方法对矿工在观看应急与正常作业场景下文字与图片素材的脑电数据进行分析.结果表明:矿工在实验素材的靶刺激下,ERP成分明显,且图片刺激效果强于文字,在200～400 ms时,P200,P300成分峰值最大;矿工大脑α节律不断下降,β节律不断上升,且β节律波幅面积...

Experimental study on EEG components characteristics of miners in emergency scenario

In order to investigate the change law of the electroencephalogram (EEG) components of miners in the emergency scenario,the EEG data of miners watching the text and picture materials of emergency and normal working scenarios was analyzed by means of EEG experiment.The results showed that for the miners under the target stimulation of experimental materials,the ERP component was obvious,and the stimulation effect of picture was stronger than that of text,the peak values of P200 and P300 components were the largest at 200~400 ms.The α rhythm of the miners’ brain kept decreasing,while the β rhythm kept increasing,and the amplitude area value of the β rhythm wave was always larger than that of the α rhythm.The study can provide scientific basis and suggestions for the assessment and training of miners’ emergency capability and the safety training of coal mining enterprises.
