摘　　要：本文通过对济宁二号煤矿11302孤岛工作面连续的矿压观测,结合工作面各种矿压显现特征,通过钻孔应力计监测、固定点观测和多点位移计观测,掌握了孤岛工作面回采过程中顶板活动规律及工作面超前应力变化情况,为工作面的顶板管理提供了依据。based on coal mining 11302 island jining no consecutive mine pressure observation, combining various mine pressure mining appeared, through the borehole stress program features anchors observation and monitoring, multipoint displacement observation, the master plan extraction process mining island roof movement rule and face, for stress changes ahead of the ceiling management to provide the basis.
