摘　　要：随着开采向深部延伸,高地应力造成巷道收缩、底鼓,矿井大型固定设备的混凝土基础产生变形、开裂、倾斜,对设备安全运行会产生比较大的影响。为此,探讨底板的变形过程及稳定条件,研究适应性较强的底板变形控制技术。Along with the stretching mining activities into deep contraction of the roadway, the expansion of the floor, and the foundation for the large stationary equipment. In order to avoid condition of the floor are investigated and the highly adaptive stability is studied ground, the high geostatic stress will cause the distortion, cracking and tilting of the concrete these, the deformation process and the stability and effective technology for strengthening floor
