Abstract: The NO.2 mining area of Ⅲ₃ coal seam was the main mining area of Xuandong Coal Mine, but it had the risk of rock burst because of the large mining depth, the complex coal seam occurrence condition, high gas content and other factors,. Taking NO.2 mining area of Ⅲ₃ coal seam as an example, it analyzed the risk of rock burst from the power source of rock burst, release medium, inducing factors, the results showed that it had high risk of rock burst. It summarized and put forward the three principles of controlling rock burst, based on this, it proposed the targeted prevention and control measures, and the micro seismic and drilling cuttings were used to check out the monitoring results. The practices proved that these measures had good effect to control rock burst.
