Abstract To get the acoustic emission(AE) characteristics of deep monzogranite and altered minerals in Lingnan gold mine during the whole failure process of loading，uniaxial compression tests were carried out using GAW–2000 microcomputer controlled electro-hydraulic servo rigidity pressure testing machine，and the acoustic emission signal was received by AE21C acoustic emission testing system. The experiment results were shown the failure and acoustic emission characteristics of the two deep rocks. Then，based on indoor rock mechanics test and on site investigation，the rock burst proneness for different rock samples in nineteenth level were determined according to the linear elastic energy criterion. Finally，the results were compared with the acoustic emission data and site actual situation，which revealed accumulating counts of acoustic emission energy for medium rock burst tendency was 15 times higher than low rock burst tendency. Therefore， accumulating counts got from indoor acoustic emission testing technology had a reference value in quickly determine the rock burst proneness， and could be used in field prediction.
