摘　　要：根据坚硬顶板断裂振动型冲击地压的发生机理,提出了冲击地压预测预报技术,经现场试验形成了“支架载荷-声发射联合观测,巷道收敛变形,煤体应力检测,煤体钻屑检测”的冲击地压综合预测预报系统,并取得良好的安全效果。Based on generation mechanism of breaking and vibration type pressure bump of hard roof, the forecast technique of pressure bump is put forward, through site test, the comprehensive forecast system of “support load-voice emission combined observation, abstrictions and deformation of roadway, the stress test of coal body and drill cuttings test of coal body” is formed and good safety result was obtained.
