| Abstract: | Acoustic emission cumulative difference indicator was proposed to evaluate the stability of underground engineering. The indicator takes into account of acoustic emission wave over a period of time, so it can predict the instability of goaf more accurately. Based on the grey theory, the GM(1,1) model of acoustic emission cumulative difference indicator is established, and applied to forecast goaf instability of the No.104 ore body in Fozichong Pb-Zn mine. The prediction has a good consistency with the actual situation. |
