Research On Unsafe Behavior And Its Coutermeasures In Coal Mine Production Team

Cognition and control of unsafe behaviors decide the effectiveness of accident prevention in coal mine. In recent years, the government paid prodigious attention to safety production of coal mine enterprise, and took a series of measures to improve production safety. The situation of production safety is better, but it is still serious in coal mining industry. Numerous coal mine accidents were investigated and the results showed that accidents above 90% happened in production team and accidents above 80% was due to unsafe behaviours in production team. Unsafe behavior in coal mine team is emphasized in mine enterprise safety management, but the study of it is not getting much more attention. It is not still clearly about what have caused unsafe behavior and the relate coefficient between the influencing factors.According to coal mine enterprise production characteristics, theories of unsafe behavior and the research purpose, this dissertation defines unsafe behavior in coal mine production team. They are investigated by using the method of questionnaire and classification, and then their specific forms are confirmed.A formation mechanism model of coal miners’ unsafe behavior is built based on risk perception, danger recognition and behavioral response of miners, and its forming pathways are given. Evolvement rules of miner’s unsafe behaviors are quantitatively analyzed based on evolutionary game theory. This dissertation proposes the taxonomy of miner’s unsafe behaviors based on how it happened, and then the characteristic of miner’s unsafe behavior is analyzed.Group unsafe behavior in coal mine production team is defined firstly. Influencing factors of it are determined form research literatures and field investigations. Grey correlation analysis is used to analyze influencing factors, and then method of AHP(Analytical Hierarchy Process) is used to arrange them according to importance. Major influencing factors are selected to be analyzed emphatically.Original theoretical formation model of team group unsafe behavior is built, and it is evaluated based on SEM(Structured Equation Modeling) with questionnaire data. According to the fitting results of original theoretical model and questionnaire data, the original model is modified, and then path analysis of modified model is implemented. The results of empirical study show that leader of team, cohesion of team, safety code of team, safety culture of team and working environment of team have remarkable effects on group unsafe behavior of team, and leader of team have most effect by direct effect and indirectly affecting team cohesion.This dissertation proposes suggestions on the countermeasures to reduce and eliminate unsafe behaviors in coal mine production team. The countermeasures include that supervising miners of unsafe behavior, selecting excellent team leader, promoting the cohesive force of team, building favourable safety culture of team and optimizing team working environment.
