摘　　要：常村煤矿21220综放工作面初采、初放期间,加强支架工作阻力、应力及微震的监测、分析,加强工作面冲击危险性预警,在发生冲击大能量破坏事件的概率增加时,及时下发预警通知单,工作面停止生产作业,采取施工卸压钻孔、断底爆破、煤层注水等防治措施解除冲击威胁,在初采、初放期间未因冲击造成设备损坏及人员轻伤等事故的发生,确保了21220综放工作面的安全生产。At the initial mining period and the primary caving period of Changcun Coal Mine 21220 fully mechanized caving face, by strengthened the support working resistance and press, and the microseism monitoring, strengthened the work of the rock burst hazard warning, when the probability of occurrence of large energy damage events that result rock burst increases, promptly issued a warning notice, at the stopping production, by constructed the pressure relief borehole, blasted to cut off the bottom, coal seam water injection to control the impact threat ,and ensure that the 21220 fully mechanized working face safety production.
