摘要： A method for anchoring a device in multilayer soil includes analyzing the soil to determine the depth, hardness and density of at least two layers of soils. The anchoring device is prepared for positioning by attaching a self-drilling bit to a bottom end of a hollow rod, attaching a drilling disc to the rod at a position above the self-drilling bit, attaching at least one helical disc to the rod above the drilling disc, and attaching a positioning plate to the rod at a distance from the drilling disc such that the distance from the bottom of the drilling disc to the bottom of the positioning plate is approximately equal to the depth of a first layer of soil. The anchoring device is drilled into the soil until the drilling disc rests on top of the second layer and the positioning plate rests on top of the first layer.

摘要： A rock bolt, particularly for use in mining, having an axial conduit, an anchor nut, and an anchor plate supported by the anchor nut for the purpose of placement on the rock, that is able to expand sufficiently and possess sufficient tensile strength, and also is able to be cut for the purpose of simplified separation of excavated pieces of the rock bolt. This problem is addressed in that the axial conduit is at least partially, and particularly entirely, made of metal and plastic, and the at least one component of the axial conduit made of metal and plastic serves to receive tensile forces.

摘要： A setting method of anchoring a fastening element (11; 41) in a constructional component (21) with a hardenable multi-component mass (31) includes drilling a borehole (22) in the constructional component (21) with a drill (36) until a borehole depth (T), which is at least by 5% greater than a necessary anchoring length (L) of the fastening element (21; 41), is reached; introducing the hardenable multicomponent mass (31) in the uncleaned borehole (22), inserting, in the borehole (22) the fastening element (11; 41) with its mixing section (13; 43) first, and power-driving the fastening element (11; 41) into the filled borehole (22) with a rotary driving tool, with intermixing of the hardenable multi-component mass (31) with drillings (23) remaining in the borehole (22), until the necessary anchoring length (L) of the fastening element (11; 41) is reached.

摘要： In one aspect of the invention, an apparatus and related methods for installation in a borehole formed in a face of a mine passage comprises an elongated bolt including a spiral shaft portion for positioning in the borehole. A hardened, stationary resin nut formed in only part of the borehole, preferably spaced from the distal end thereof, receives the spiral shaft portion of the bolt. Consequently, rotation of the spiral shaft portion within the hardened resin nut serves to move the bolt within the borehole, such as for purposes of tensioning.

摘要： A resin bonded mine roof bolt having an elongated rod with a drive head at one end and an expansion anchor threaded onto the other end. A segmented resin compression layer covers a portion of the rod below the expansion anchor. When installed in a mine roof bore hole with curable resin, the resin compression layer mixes the resin and partially fills the bore hole to minimize the amount of resin needed to anchor the bolt. Individual segments of the layer are tapered to create a wedging force on resin with the bore hole. The expansion anchor is expandable upon initial hardening of the resin to tension the bolt.

摘要： A rock bolt anchor having chemical and mechanical anchoring means includes a top portion permanently fixed to a bottom portion. The top portion carries a package of resin. A spring loaded mechanism pressurizes the package and squeezes the resin out when the package is lanced. The bottom portion main body carries a pair of opposed outer shells in a dove tail joint on opposed tapers. The annulus adjacent to the rock bolt anchor is sealed by top and bottom bulkheads. The bottom portion is threaded onto a rock bolt. A hollow and ported lance is threaded onto the exposed end of the rock bolt. The combination is inserted into a drilled hole and the rock bolt rotated. The lance rises and pierces the package releasing into the sealed annulus. Continued rotation of the rock bolt, forces the main body down and the outer shells up the tapers compressing them against the wall of the drilled hole.
