An analysis on mechanism of rock burst during deep mining excavation in Linglong gold mine

Linglong Gold Mine is in the high in-situ stress area.Rock mass is stiff and brittle granite.The Mine is a deep well mine now.The mining depth is more than 1000m and will exceed 1000m in the future.Rock burst will be a serious problem for the Mine during deep mining excavation.So the predication and prevention of rock burst play an important role in the control of deep ground pressure for the Mine.Based on the investigation,SEM,indoor rock mechanics experimentation,CSIR and measurement of in-situ stress,the author analyzed the mechanism of rock burst during deep mining excavation in the Mine and advanced prevention methods.
