Bolt support has been the main support form of the mine roadway in the underground endineering because of its obvious technical and economical superiority.Th theory of bloting is maturing with the practice of bolting technology continuously enriched.For this study,we built a mechanical modle for bolting,which represented the effect of a bolt on the surrounding rock in roadway. Simultaneously,we use the displacement method in elastical to deduce the elastic solution of forcing at point in the interioe of a semi-infinite solid. And we analyzed factors affecting the radical compression of the bolt on the surrounding rock. The results indicate that 1) the maximum radical compression stress declines first and then rises with the increase in depth from the surface of the anchorage surrounding rock and 2) the size of the radical compression area is mainly determined by the length of the bolt.
Keywords:Solid mechanics;mecnanical mechanism;elastic theory;radical compression;the length of the bolt
