Abstract: according to the problems containing dated forcast methods, pointless control and a lack of technology system in prevention and control technologies against pressure bump in Xinzhouyao coal mine, based on pressure bump characters and regular patterns analysis, features and regularities were summarised, That rock burst occurred in adjacent air along the trough, the work surface, forward speed > prone to impact of 2 meters are prone to the impact and depth of the mining of 240m-350m; Through experimental analysis, in-situ stress measurement and field practice analysis, three points are obtained,coal seam with strong impact force, strong horizontal structure stress, and the muti-stress plused by mining. 55 prevention and control tecnologies was discovered, including a forcast system of five methods: drill, micro shake, mine pressure, electromagnectic, and full utilization, and a control system of five ways: release, break, protecting, prop and avoiding. The applications of Xinzhouyao mine rockburst occurrence by a decrease of 34 since 2009 to 4 in 2014, the treatment effect is significant.
