The　rockburst　disaster　triggered　by　the　nonlinear　large-deformation　characteristics　of　deep　rock　masses　has　been　a　worldwide　problem　in　geotechnical　engineering,　severely　constraining　construction　progress　and　safety　in　engineering　projects.　Therefore,　it　is　imperative　to　intensify　in-depth　research　on　rockburst　prevention　measures.　Based　on　the　principle　of　steel　pipe　compressive　deformation,　a　novel　steel　pipe　shrinkable　energy-absorbing　bolt　constant-resistance　large-deformation　bolt　was　proposed,　which　can　provide　a　high　constant　resistance　while　accommodating　a　substantial　amount　of　deformation.　Building　on　previous　research,　the　impact　resistance　of　the　steel　pipe　shrinkable　energy-absorbing　bolt　constant-resistance　large-deformation　bolt　was　investigated　through　drop　hammer　impact　tests.　The　test　results　indicate　that:　during　the　impact　process,　the　working　resistance　of　the　steel　pipe　shrinkable　energy-absorbing　bolt　constant-resistance　large-deformation　bolt　remains　stable　within　the　range　of　150　kN　to　180　kN,　demonstrating　notable　constant-resistance　characteristics;　the　bolt　absorbs　a　significant　amount　of　energy　with　high　efficiency,　capable　of　absorbing　up　to　53　kJ　of　impact　energy　in　a　single　instance;　throughout　the　impact,　the　compression　rate　of　the　specimen　only　decreased　by　0.54%　to　1.43%,　indicating　relatively　stable　deformation.　The　steel　pipe　shrinkable　energy-absorbing　bolt　constant-resistance　large-deformation　bolt　exhibits　excellent　impact　resistance,　providing　robust　technical　support　for　the　prevention　and　control　of　rockburst　disasters　during　underground　engineering　construction.　©　2024　Biodiversity　Research　Center　Academia　Sinica.　All　rights　reserved.
