Abstract: In order to explore the formation path of unsafe behaviors of coal miners in the perspective of informal organizations, and to find out the factors influencing unsafe behaviors of coal miners, based on the existing research, the hypothesis that the relationship between organizational environment and social network is a guide to the unsafe behavior of coal miners is put forward, by using SPSS analysis software and AMOS modeling tool to process data and model fitting, the formation path of unsafe behavior of coal miners was determined. The results show that the organizational environment and social network directly or indirectly affect the unsafe behavior of coal miners, and there are two main paths for the formation of unsafe behavior, they are organizational influence → unsafe supervision → precondition of unsafe behavior → unsafe behavior of coal miners, degree of association → dependence → unsafe behavior of coal miners. It can effectively reduce the occurrence of unsafe behavior of coal miners by monitoring social network relationship and promoting informal organization atmosphere of coal miners through improving organizational environment and behavior, to provide new ideas for coal mine enterprise management decision-making.
