| Abstract: | By use of the measurement system of KS digital acoustic wave processing apparatus, this paper deals with the experimental study on the correlation between the changes of rock acoustic parameters and the all stress-strain process of rock specimens. In order to analyze the rock mass stability in situ, the acoustic wave measurements have been carried out in underground roadway in Xishan Coal Mine. The rock acoustic parameters in this paper include wave amplitude, spectral amplitude, spectral area, spectral density, wave velocity and attenuation coefficient etc. |
