摘　　要：利用岩体声发射技术对竖井围岩稳定性进行监测可以克服传统的位移、应力监测的弊端，实现全天侯连续长期监测。本文介绍了凡口铅锌矿新副井围岩声发射智能监测系统、监测仪器、监测方法及监测结果，并根据监测结果对新副井围岩的稳定性作了初步评价。AbstractUsing acoustic technique to monitor the stability of vertical shaft , whichovercomes the backwards of conventional displacement and stress measuringmethods, enables to realize continually and long term monitoring undervarious conditions. This paper introduces a intellectual system, instrumentand results of acoustic monitoring used at the new auxiliary shaft ofFangkou zinc mine. And the preliminary stability assessment of rocksurrounding the shaft is provided.
