Abstract: Is aimed at solving the problem that merging of coal mine post standard operating procedure and risk prccontrol management system of safety in coal mine. According to summarizing both of the two’s development course, analyzing the intension and characteristics of them,researching the relationship between them , we point out that the coal mine post standard operating procedure is the effective means to realizing the risk prccontrol management system of safety in coal in coal mine, they exist side by side and play a part together. Then we point out the merging foundations, principles and methods according to the relationship between them. The research findings of this paper provides a reference that merging of coal mine post standard operating procedure and risk prccontrol management system of safety in coal mine.
