| Abstract: | Rockburst is a serious problem in deep mining of Sanshandao Gold Mine.In order to ensure the safety of the working face, this article puts forward a depressure release scheme, establishes a three-dimensional mathematical model to analyze the pressure relief effect, and carries out the implementation through the deep-780 m stope of the mine.The stress test results show that pressure relief holes can effectively form pressure relief area and reduce the probability of rock burst. |
