| Abstract: | The STL-12 multi-channel acoustic emission monitoring system is introduced into the mine and the acoustic emission monitoring technology is adopted to real-time monitor the goaf pressure for all day. Then，the reasonable and effective monitoring method is proposed. After analyzing the monitoring data of a whole year，the feature of the acoustic emission waveforms，and the factors and features of the common waveforms when rocks are broken are summarized. It is determined that the goaf is stable at present，and the safety production of the mine can be ensured. |
