| Abstract: | According to the properties of trimini-diameter rockbolt, a kind of trimini-diameter rockbolt held with quick cement is workout.lts held section has treelike shape easily manufactured, installed and of greater resistance to the pull-out force.The held length,ratio of water to cement and roll specifications of the rockbolt are adjusted. Its anchoring reliability has been proved by underground pull-out test.In the industrial trials,this kind of rockbolts with metal net is successfully used to support an opening in coal. |
