| Abstract: | This paper introduced current abroad and domestic status of pre-tightening force of anchored bolt and analyzed its influence factors.New-style high-efficiency antifriction gasket was developed which could make anchored bolt's pre-tightening force improved over 1 time and reached 50% of yield force of anchored bolt under 300N·m torque moment.This provided good condition for spreading anchored bolt support with high pre-tightening force in deep mine and dynamic pressure roadway. |
