    摘要： In order to provide an anchor site in a matrix of solid material which has an accessible face, a socket is formed in the material through the accessible face. A shaft such as an anchor bolt is inserted in the socket, leaving an accessible emergent outer end portion. Via the outer end, explosive force is introduced to or generated in a central cavity of the shaft, which explosive force dislodges and deploys radially essentially outwardly at least one key at at least one level within the socket. Various ways for producing the explosive force are described.

    摘要： When securing a rock bolt in a drilled hole in the rock the bolt having a conical end, is inserted to the desired depth in the hole. A gun, charged with a sleeve, is applied on the outer end of the rock bolt, and the bolt is centered in the gun barrel. The sleeve is shot into the hole at a high speed to be wedged in the gap between the conical end of the bolt and the wall of the hole.

    摘要： A ground anchor retaining assembly for providing a ground-retained anchor to restrain an object, such as an above ground structure, for example, a tower or pylon connected to it. The assembly is adapted to be received within a borehole within the ground and comprising an anchor shaft; a housing connected to the shaft and surrounding at least a part of the anchor shaft; the housing with the part of the shaft defining a chamber; and an effective amount of an explosive within the chamber connectable to a detonator to effect detonation of the explosive to effect deformation of the housing as to provide frictional ground retention of the housing within the ground. The assembly also may be used to provide ground anchors within the walls, roof and floors of mine shafts and tunnels.

    摘要： An anchor bolt to be anchored by an explosive charge in a blind bore in a solid material, in particular a rock face or concrete, has a deformation chamber containing the explosive charge. To achieve inexpensive manufacture of the anchor bolt, simple mounting and high withdrawal values of the anchor bolt to be anchored, the deformation chamber open towards the leading end of the anchor bolt is closed by a stopper. A striking pin projecting beyond the leading end of the anchor bolt is inserted and guided in the stopper, so that as the rear end of the anchor bolt is hit the striking pin contacts an ignition capsule arranged between the stopper and the explosive charge.
