摘　　要：21170下巷掘进工作面采深已达780m,属于采深和逆冲断层共同作用的高应力工作面。掘进期间煤炮频发,巷道变形快,高应力区位置难以确定,防冲措施施工没有针对性,防冲效果差。Sos微震监测系统能实时监测煤炮事件并科学定位,预测冲击地压高应力区准确率高,通过采取针对性的卸压措施后,工作面冲击危险程度大大降低,确保工作面安全生产。The heading depth of 21170 under has reached 780m, belong to the mining depth and the thrust of the joint action of high stress working face. During the tunneling, the coal burst take place frequently, the roadway deformation is fast, the position of the high stress area is difficult to be determined, the construction of the rock-burst preventing measures is not targeted, and the effect is poor. Sos microseismic monitoring system can real-timely monitor the coal blasting events and scientifically locate the rockburst position, by taking the pressure relief measures working face danger degree is greatly reduced, to ensure the safety of working face.

关 键 词：工作面掘进 预测预警 冲击地压防冲
