High　stress　in　surrounding　rock　will　lead　to　serious　problems,e.g.,rock　burst　in　hard　rock　and　large　defor-mation　in　soft　rock.The　applied　support　system　under　high　in-situ　stress　conditions　should　be　able　to　carry　high　load　and　also　accommodate　large　deformation　without　experiencing　severe　damage.In　this　paper,a　specially　designed　energy-absorbing　component　for　rock　bolt　and　cable　that　can　solve　the　above　problems　was　proposed.The　energy-absorbing　component　can　provide　support　resistance　by　plastic　deformation　of　the　metal　including　constraint　annulus　and　compression　pipe.For　practical　engineering,two　forms　were　proposed.One　was　installed　in　the　surrounding　rock　by　reaming,and　the　other　was　installed　directly　outside　the　surrounding　rock.During　the　dilation　of　the　surrounding　rock,the　relative　displacement　of　constraint　annulus　and　compression　pipe　occurs,resulting　in　deformation　resistance.Deformation　resistance　is　transmitted　to　the　rock　bolt　or　cable,providing　support　resistance.The　lab　test　and　numerical　simulation　showed　that　the　energy-absorbing　component　can　perfectly　achieve　the　large　deformation　effect,the　deformation　amount　is　as　high　as　694　mm,and　the　bearing　capacity　is　stable　at　367　kN.The　field　application　tests　were　carried　out　in　the　mining　roadway　of　Xinjulong　coal　mine,and　the　results　showed　that　the　new　type　of　cable　can　ensure　itself　not　to　break　under　the　condition　of　large　deformation　of　the　surrounding　rock.The　energy-absorbing　component　has　the　superiorities　of　perform-ing　large　constant　resistance　and　controllable　deformation　to　effectively　control　the　unpredictable　disas-ters　such　as　large　deformation　in　soft　rock　and　rock　burst　in　hard　rock　encountered　in　deep　strata.
