摘要
在深矿井中,由于竖井穿越不同岩性的岩层,每个岩层在地质应力的作用下产生不同的流变速度及抗剪切力的不同反应,出现了井壁的围岩变形、位移和裂隙。为控制围岩变形,在提高支护强度的同时,必须对其进行柔性支护以适应围岩变形。
In the deep mine,as the shaft passing through different rock layers,every rock stratum produces the differente flow varieble speed and the differente reaction to shear force by the action of geolongical stress,and appeared surrounding rock deformation,position moving and crack.For controlling rock deformation must do soft support in oredr to fit surrounding rock while increasing support strength.
