Research On The Safety Leadership Of Senior Managers And The Mechanism For Its Influence On Near Miss In Coal Mine

Near misses may have occurred several or hundreds of times before an accident,but they are easily overlooked because no loss or only a slight loss is caused.The lack of near miss controlling before an accident is one of the important reason for not effectively curbing the occurrence of coal mine accidents.In order to serve the near miss management in coal mines more effectively and achieve the objective of Prevention Beforehand,the most urgent problem is to identify the disaster mechanism of near miss.There are a lot of management failure factors contributing to near miss,so the effective management is an important way to improve employee' safety behaviors and prevent near miss.The safety leadership from the senior managers plays an important role in safety production.And the management of near miss in coal mines also requires senior managers' support and promotion.Thus it's of great significance to study the coal mine senior manager' safety leadership and its influence on the near miss in a in-depth and systematic way for enriching the disaster mechanism of near miss and enhancing and guaranteeing high-reliability safety in coal mines.The senior managers' safety leadership structure is determined.After a review of relevant literature,The paper summarizes the dimensions of safety leadership of senior managers in coal mines based on the characteristics of the coal industry,coal mine accident cases,and then a clear initial project of each dimension is constructed by interviewing 24 coal mine senior managers.The initial project are screened and streamlined by reliability analysis and exploratory factor analysis based on a small questionnaire data,and eventually formal questionnaires are established.The safety leadership structure of senior managers has been verified by structural equation modeling techniques based on the formal questionnaire data,concluding that the safety leadership of senior managers in coal mines contains 28 elements corresponding to 5 dimensions,safety quality,safety care,safety guidance,safety motivation and safety controlling respectively.The mechanism model of the influence of senior manager' safety leadership on near miss in coal mines is constructed.Based on the theory of accident-causing theory,organizational behavior theory,leadership theory,regulatory focus theory,the paper discusses the direct impact of coal mine senior managers' safety leadership on near miss,and holds that senior managers' safety leadership indirectly affects the near miss through the safety climate in coal mines as an intermediary role,and the process is influenced by the chronic regulatory focus.According to this,the mechanism model of the influence of senior manager' safety leadership on near miss in coal mines is constructed,and then the paper puts forward the hypothesis of the main effect of senior managers' safety leadership on near miss,the hypothesis of the intermediary effect of the safety climate in coal mines and the hypothesis of the adjustment effect of chronic regulatory focus.The relevant research variables are designed and measured.Based on the literature review and the characteristics of the coal industry,the paper studies the organizational safety climate and the structure of near miss in coal mines,and develops the measurement scales.The tendency of chronic regulatory focus of senior managers is measured by the chronic regulatory focus scale developed by Lockwood(2002).Through the analysis of the reliability and exploratory factor of the small sample test of each measurement scale,the measurement indexes are reduced and optimized.Based on the confirmatory factor analysis of a large sample test,the validity and stability of each measurement scale structure are verified.The results show that the measurement scales of the organizational safety climate in coal mines,the near miss in coal mines and the chronic regulatory focus have good internal consistency and structural validity,which lays the foundation for the verification of the mechanism of the senior managers' safety leadership on near miss in coal mines.The mechanism model of the influence of senior managers' safety leadership on near miss is tested by empirical analysis.Based on the structural equation model,the PA-LV hypothesis model of the influence of senior managers' safety leadership on near miss is constructed to test the hypothesis between the main effects.The results show that the five dimensions of senior managers' safety leadership in coal mines have a significantly negative impact on near miss in coal mines,namely,better safety leadership can effectively reduce the occurrence of near miss in coal mines.Based on the structural equation model,the PA-LV mediator model of the organizational safety climate in the impact of senior managers' safety leadership on near miss in coal mines is constructed,and is verified by Bootstrap method.The results show that the dimensions of senior managers' safety leadership in coal mines have significantly positive impact on the organizational safety climate of the coal mines,the organizational safety climate has significantly negative impact on near miss in coal mines,and the mediating effect of the organizational safety climate of coal mines is verified.And then the mediating effect of the dimensions of the organizational safety climate as multiple parallel mediating variables is verified by Bootstrap method.The results show that the mediating effect of the combined function of the dimensions of the organizational safety climate is significant.However,there is a difference in the mediating effect of each dimension.The adjustment effect of chronic regulatory focus on the direct impact of senior managers' safety leadership on near miss in coal mines is tested by Bootstrap model.The results show that the negative impact of safety leadership on near miss is strengthened by the senior managers with middle-level and high-level promotion focus and prevention focus,which has a positive effect on controlling near miss in coal mines.However,the low-level promotion focus and prevention focus of senior managers of coal mines have an insignificant adjustment effect of senior managers' safety leadership on near miss.And then the paper tests the mediating role of organizational safety climate in the adjustment effect of chronic regulatory focus.The results show that the mediating effect of organizational safety climate is strengthened by the low-level,middle-level and high-level promotion focus of senior managers,but it is strengthened only by the middle-level and high-level prevention focus of senior managers.The paper identifies the structure of safety leadership of senior managers,clarifies its influence on near miss in coal mines,and enriches the mechanism of near miss in coal mines,which provides a theoretical guidance to senior managers' safety leadership training and near miss management,and it is helpful to upgrade the prevention of accidents and the control of risks to a higher level.
