Study on rule of mining based on microseismic monitoring in deep stope

Dongguashan Copper Mine is one of the deepest metal mines with rockburst proneness at present in China. In order to hold regularities of rockburst occurrence and adopt effectively control measures on time, Dongguashan Copper Mine has installed an ISS microseismic monitoring system, which can make a real-time monitoring of rock mass respond to mining. In this paper firstly geological condition, mining methods and sensors layout of initial panel are described. On the base of processing events waveform and cluster analysis primarily, by uses of seismic parameters analyzing stress or strain rule of stope during different mining stages . Combined with the actual destruction of mine incidents,it is pertinence analysized. This result will provide guidance for adjacent stope mining subsequently and pillar stability control strategy.
