Study of Rock Acoustics Characteristic and Application in Safe Prediction of Stope in Fengshan Copper Mine

摘要

Firstly, the acoustic characteristic of different rock and ore in Fengshan Copper Mine is studied. Based on it, the rock stability is classified as three ranks combined with rock property. And the monitoring measures of acoustics are set up for stope safety. Furthermore, the acoustic emission characteristic in the pit is also studied. According to the observation results for a long time, the acoustic emission characteristic is basically defined as rock destroys. Moreover, based on the time series parameters deduced from the acoustic, grey theory is used to predict destabilization in the stope.
