摘要：针对张店矿-1000m大巷底板岩性松软、巷道围岩应力高，且巷道底鼓变形严重，分析了深部高应力作用下巷道底板压曲作用机理，并应用FLAC2D5.0模拟软件分析了深部巷道在高应力和底板松软条件下的底板变形影响，提出了高强度弧形混凝土浇灌和反底拱中空注浆锚索对巷道进行加固支护。矿压观测结果表明，施工注浆锚索和混凝土10天后，底鼓变形速度急剧下降，平均速度小于2mm/d。

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.
