Abstract: According to the analysis on unsymmetrical-information-dynamic game model, we could find out that in the circumstance of the existing producing mechanism, in which the functions between the government and the enterprise have not been definitely plotted out, the government has not paid enough attention to the safety production supervision of the coal mine enterprise. In the existing mechanism, the safety production of the coal mine enterprise and the supervisor's inspection have the Nash equilibrium or Mixed Nash equilibrium in the complete and perfect information condition. On the basis of the model, the effective supervising methods could be established that first of all, build the scientific idea of development for people; secondly, strengthen the inspection and reduce the lure of the extra-income; thirdly, establish an effective publishing and encouraging mechanism for the supervisor; fourthly, reduce the social burden of the coal mine enterprise.
