It plays a very important role to strengthens the surrounding rock of the roadway of mines and tunnels, it makes the surrounding rock support itself, prevent displacements of rock. Now high strength rock bolt is not only used in mines, but also used in engineering technology to strengthen the main body of slopes, tunnels and dams, it is called soil nail or ground anchor in some applications. As a tensile member deep into the rock or soil, rock bolt is connected to the engineering structure at one end and into the ground layer at the other end.
