| Abstract: | 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. |

| Keywords: | deep mining deep strata multipoint displacement meter real time monitor strata movement law |
