摘　　要：现有的监测大多在巷道顶板5～8m深的范围展开,本文通过深孔多点位移计实时监测了工作面回风巷和运输巷顶板岩层0～20m深处范围内的岩层移动规律。获得了不同回采阶段覆岩移动变形规律,并根据监测曲线获得了周期来压步距。Most of the existing observations are focus on the roadway roof movement in the range of 5-8 meters in the literatures.In this paper,multipoint displacement meter has been applied to real-time monitor the movement law of strata locating in the material and transportation tunnel in the range of 0-20m.The movement law of strata under different back mining stages has been obtained.Based on the movement curve of strata,we deduce the period pressure step.These may be helpful for the mining engineering.
