Abstract:

In order to reduce the occurrence of safety accidents in coal mine production, from the perspective of emotion control, based on Valence-Arousal (V-A) emotional model, combined with emotional arousal methods and physiological measurement techniques, a cognitive experiment of miners' safety behavioral competence was conducted. Attention and decision-making time under different emotional states were measured. The regression analysis was used to investigate the continuous effects of degree-of-arousal on attention and risk preference under different emotional valence. The results show that in low degree-of-arousal and positive emotions, decreasing degree-of-arousal leads to weaker attention and more risk aversion in decision making in miners. In the high degree-of-arousal and positive emotions, with the increase of degree-of-arousal, the level of attention and risk aversion of miners in decision-making first increases and then decreases, until it is lower than neutral emotions. In low degree-of-arousal and negative emotions, decreasing degree-of-arousal would make miners pay less attention and have lower risk aversion in decision-making. In the high degree-of-arousal and negative emotions, an increase in degree-of-arousal increases and then decreases the attention and risk aversion in decision making, even until they are lower than the level of neutral emotions. By contrast, in the high degree-of-arousal range, increasing degree-of-arousal in positive emotion is more likely to reduce miners' safety behavioral competence to lower than the level of neutral emotional.
