摘　　要：为有效防治冲击地压,以东滩煤矿3305工作面为研究背景,划分3305工作面冲击危险性。结果表明:3305工作面轨顺49号收尺点至掘进通道位置共计480m具有强冲击危险性;轨顺其他区域和运顺与断层之间煤柱小于30m的区域,运顺切眼Ⅰ至225m收尺点位置具有中等冲击危险;运顺侧收尺点225~517m位置具有弱冲击危险。对不同冲击危险程度的区域采取不同程度的解危措施,同时采用应力在线监测对巷道应力进行实时监测。最后对3305工作面监测结果及解危措施进行了效果检测,确保了安全生产。For the effective prevention of rock burst, using Dongtan coal mine NO.3305 working face as the research background, divided into NO.3305 working face of the impact of risk. The results showed that the NO.3305 working face of rail Shun 49# ruler receiving points to a total of 480 m tunneling channel position with strong shock hazard; area along the rail and other regions and transported along fault coal pillar is less than 30 m transport crossheading area, cut 1 to 225 m ruler receiving position have medium impact risk; transport crossheading side ruler receiving point 225 m to the 517 m position has a weak impact of risk. Take different controlling measures on different danger degree area, while take real-tine monitor using on-line monitoring system to roadway stress. Finally take effect detection of the monitoring results and controlling measures of the NO.3305 working face, to ensure the safety of production.
