Abstract:

Abstract：Aiming at the loose-soft floor，the high stress of surrounding rock and the serious floor-heave in the -1000m main entry of Zhangdian Mine，analyses the mechanism of buckling effect on roadway floor under deep high stress，analyses the deep roadway floor deformation influence under the conditions of high stress and loose-soft floor by using FLAC2D5.0 simulation software，proposed that using arc high-strength concrete pouring and hollow grouting anchor cable to reinforce support.The strata control observation shows that the floor-heave deformation velocity decreased obviously after 10 days, and the average velocity is lower than 2mm/d.

Key words: Key words: heave of roadway, numerical simulation, surrounding rock control, high stress
