Abstract: In order to effectively play the positive role of the new generation of miners in the safety management of coal mining enterprises, based on the behavioral motivation theory and social exchange theory, we construct the structural equation model of job satisfaction, subjective well-being, job involvement and safety performance of the new generation of miners. Hierarchical regression and Bootstrap method were used to test the direct effect and mediation effect of 256 samples data of new generation miners. The results show that the job satisfaction, subjective well-being, job involvement and safety performance of the new generation of miners are positively correlated; job satisfaction can indirectly affect safety performance through two paths: the independent mediating role of subjective well-being, job involvement and the chain mediating role of them.
