Spectrum Characteristics of Acoustic Emission Signals for Sandstone Instability

Spectrum Characteristics of Acoustic Emission Signals for Sandstone Instability

In order to predict the rock rupture and instability, acoustic emission signals of natural sandstones and hydrous sandstones are analyzed through the Fast Fourier Transform and the Welch method. It is found that the acoustic emission signals of the hydrous sandstones have narrower range of frequen...
