摘　　要：本文主要介绍了岩体声发射技术在小铁山矿的应用与实践。通过现场研究得出岩体从稳定至破坏状态与声发射之间的关系 ,从而为采场冒顶片帮预报提供了理论依据。The application and practice of acoustic emission technology of rock mass was presented in this paper.The relationship between the states of rock mass transferring from stable state to destructive state and the acoustic emission was educed through field study,as a result,this would provide a theoretical criterion for the prediction of roof caving in stope.
