The basic principle of the spectral analysis method is elaborated. The self-power spectrum of mine discharge and rainfall are respectively calculated, and their mutual-power spectrum is also calculated. The test method of hidden periods and general method of smooth power spectrum are given. The application results show that the periods of the mine discharge's time series and their correlation can be well determined by the spectral analysis, which can provide quantitative basis for revealing inner mechanism of mine underground water system, and predicting and controlling mine discharge.3figs.,5refs.
