    摘要： A resin bonded mine roof bolt (10) having an elongated rod with a first end (14), a second end (16), and a resin control surface (24) positioned on the rod between the rod first and second ends. The resin control surface has a channel (30) extending along the length of the bolt for distributing resin and interrupted spiral threads for mixing resin. When installed in a mine roof bore hole with curable resin, the resin control surface mixes the resin and partially fills the bore hole to minimize the amount of resin needed to anchor the bolt.

    摘要： A mine roof bolt for a grouted bore hole in a roof of a mine. The mine roof bolt includes an elongated member having a cross-sectional diameter less than that of the bore hole, a first end, and a second end. The elongated member has deformations such that axial tension on the bolt results in axial movement between the elongated member and the grout and results in confined compression of the grout between the bore hole and the elongated member surface to facilitate anchorage of the elongated member with grout to the mine rock in which the bore hole is disposed. The mine roof bolt includes a flange disposed adjacent to the second end. A method for supporting a mine roof. A method of making a mine roof bolt.

    摘要： A mine bolt for a bore hole in a roof of a mine. The bolt comprises a tube having a cross-sectional diameter less than that of the bore hole, a hollow interior, a first end, and a second end having an opening in communication with the hollow interior. The bolt comprises a flange disposed adjacent to the second end. The bolt can include an anchor means implaced in the tube and an elongated member disposed in the tube and extending from the anchor means out the tube to the second end. A method for supporting a mine roof. A method of forming a mine bolt.
