采动巷道岩体变形与锚杆锚固力变化规律

Regularity of Deformation of Rocks Around Roadway Under Mining Influence and Change of Rockbolt Resistance

阐述了采动巷道围岩的变形规律，探讨了低阻力端锚和高阻力全锚锚杆在巷道围岩变形损伤过程中锚固力的变化规律，揭示了锚杆支护与围岩的作用机理。

Based on the characteristics of rock deformation around roadway under mining influence, the regularity of resistance change of point and fullyanchoraged rockbolts in the process of deformation and damage of rocks is investigated. And the mechanism of interaction between bolts and surrounding rock is deeply discussed. The research lays a foundation for the layout of bloting of roadway under mining influence and for enlarging the application scope of rockbolts.
