Abstract The stability change of surrounding rock supporting system in mine is taken as an information source and the support reliability is treated as a handling process of information collection，transmission，process and feedback. By analyzing the relation between information entropy and reliability of the mineral well，and the concept of reliability entropy is obtained. Since the information entropy represent uncertainty of system or degree of disorder，the reliability entropy models of support system in mines and calculation method are set up，which express an average reliability of system. This method has been applied in practice，and a good effect is realized.
