The Experimental Research On The Impact Of Unsafe Emotion On Miners' Decision-making Under Risk

Through the analysis of major fatal accidents occurred within 30 years in China's coal mines,it showed that human errors accounting for up to 90%of the total accidents.Miners'risk decision-making is a crucial factor in determining whether to implement unsafe behavior.And emotion also has a direct influence on the process of information receiving,processing and decision-making.In the complex and harsh operating environment,the miners are prone to have a variety of unsafe emotions and their fluctuations may affect the outcome of risk decision-making,which may result in unsafe behaviors and further lead to accidents.Therefore,the purpose of this paper is to study how unsafe emotions affect miners' decision-making under risk in order to find the relationship between unsafe emotions and miners'decision-making under risk and reduce the occurrence of human-caused accidents.Based on the review and summarization of past research and combined with the practical situation of coal mine enterprises,this study conducted research on how the three specific unsafe emotions affect risk decision-making by adopting questionnaire method combined with the experimental method,and used paired-samples T test,variance analysis on the experimental data for statistical analysis.The main research contents and conclusions of this paper are as follows:First of all,on the basis of literature review and interviewed with relevant personnel,the paper designed and prepared miners' emotion questionnaire and then selected four representative coal mines to conduct a questionnaire survey,collected 254 questionnaires and analyzed by adopting SPSS22.0 statistical software.It is concluded that anxiety is most prevalent in miners' unsafe emotions,followed by impatience,fear,anger,boredom,nervousness and so on.Secondly,after identifying the types and sequencing of the miners' unsafe emotions,investigated the effects of emotion-induced materials and screened emotion-induced materials through the predictive experiments.The paper used video materials with multiple channels to induce fear and anger emotion and used "digital countdown tasks" to induce anxiety emotion.The evoked effects of three unsafe emotions in the laboratory were,in turn,fear,anxiety,and anger emotion.Thirdly,the paper further studied the impact of three specific unsafe emotions on the miners' risk decision-making using the Tobii T60XL eye tracker and BioLab human-data synchronization acquisition system.The experimental results show that the impact of three specific unsafe emotional states on risk decision-making behavior is that anxiety and fear emotion tend to risk aversion and anger emotion tends to risk seeking.Cognitive efforts spent in three specific unsafe emotions manifests as fear emotion>anger emotion>anxiety emotion.In the T1 stage,the physiological index of three specific unsafe emotions is fear emotion>anxiety emotion>anger emotion,and in the T2 stage,fear emotion>anger emotion>anxiety emotion.Finally,on the basis of theoretical analysis and experimental research,the paper put forward effective practical suggestions to effectively control unsafe emotions from the two aspects of miners individual and coal mine organizing management.
