Ground Tunnelling Expansion Shell Rock Bolt is a kind of rod that is anchored in the rock mass.
The use of anchor bolt to support the roadway is to drill holes in the surrounding rock after the roadway is driven, and then install the anchor bolt in the eye to strengthen the surrounding rock of the roadway manually.
The anchor rod has many advantages: saving pit wood and steel, reducing support costs, small excavation section, small deformation of the roadway, low maintenance costs, safety, portability, can reduce physical labor, reduce ventilation resistance, is conducive to the construction of a lane and speed up the excavation speed, wide range of use,strong adaptability, reduce the amount of transportation, is conducive to the transportation and upgrading of the mine. However, the bolt can not prevent the weathering of surrounding rock, can not completely prevent the fracture rock spalling between the bolt and the bolt, therefore, the bolt combined with other supporting measures, such as metal mesh, will achieve better supporting effect.
