    • Abstract
  • With the acoustic emission(AE) instrument of SYB-4 and the help of the rock acoustic parameter dynamic testing system,the acoustic emission characteristics in the process of uniaxial compression test of Gaofeng limestone in Guangxi Province is studied.Based on the experimentation data collected from limestone's uniaxial compression,the principle of the AE and the breakage mechanism of the limestone is analyzed.The test study shows that: out of the initial stages the relationship between the acoustic emission and the displacement of limestone is in evidence,which caused by forming of micro-fractures and expending of original fractures,and the relationship can be used to monitor the stability of mine rock mass.
