| Abstract: | 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. |
