摘要： An elongated channel beam for supporting the surface of an underground rock formation includes a base portion with a bearing surface for contacting the rock strata and an opposite surface having a longitudinally extending central rib and flanged edges for resisting deflection and bending of the channel beam under the load of the rock strata. A plurality of openings spaced a preselected distance apart extend through the central rib. A bearing plate is positioned in overlying abutting relation with each opening in the channel beam. The bearing plate includes embossed areas and longitudinally flanged edges that overlie in abutting relation the central rib and flanged edges of the channel beam. The bearing plate is restrained from longitudinal and lateral movement on the channel beam. Anchor bolts extend through the aligned openings in the bearing plate and channel beam into bore holes drilled in the rock formation. Tightening the anchor bolt compresses the bearing plate against the channel beam with the compressive forces distributed over the surface of the bearing plate and transmitted throughout the channel member to support the rock formation.

摘要： A pair of truss brackets are secured to the roof of an underground passage adjacent to opposing ribs of the passage. The truss brackets each include a roof engaging surface and a truss supporting arm member extending from the roof engaging surface. A pair of U-bolts are supported by the arm members of the truss brackets. Each arm member extends horizontally from the truss bracket to an enlarged end portion of the arm member. The U-bolt is horizontally movable in a vertically hanging position on the arm member and is restrained by the enlarged end portion from disengagement from the arm member. The U-bolts are pivoted on the truss brackets to a horizontal position for connection to truss members which are connected to each other and tensioned to apply an uplifting force to the roof. As the truss members are connected and tensioned, the U-bolts are retained for a range of horizontal movement on the arm members to facilitate adjustments in the position of the U-bolts on the truss brackets.

A plurality of openings spaced a preselected distance apart extend through the central rib. A bearing plate is positioned in overlying abutting relation with each opening in the channel member. The bearing plate includes embossed areas and longitudinally flanged edges that are complementary in shape with the central rib and flanges on the channel to securely engage the bearing plate on the channel member. Thus, the bearing plate engages the channel member to restrain longitudinal and lateral movement of the bearing plate on the channel member and stiffen the channel member to resist bending. An anchor bolt extends through the aligned openings in the bearing plate and channel member into a bore hole drilled in the rock formation. Anchoring the bolt in the bore hole compresses the bearing plate against the channel member to urge the channel member into compressive relation with the surface of the rock formation to support the rock formation.

摘要： A tensionable combination mine roof bolt is disclosed for use in resin grouted applications. The mine roof bolt includes a lower rod member having a rotatable bolt head at a first end thereof supporting a bearing plate and a threaded second end spaced from the first end. A coupling threadingly receives the lower rod member therein. A shearable stop device, such as a shear pin, is positioned within the coupling and adapted to stop the threaded lower rod member at a first position for rotation of the cable mine roof bolt during installation. After an upper portion of the cable mine roof bolt is secured, the shearable stop mechanism is subsequently sheared by the lower rod member to allow for tensioning of the cable mine roof bolt. A flexible multi-strand cable is coupled to the coupling device and forms the attachment point for the cable mine roof bolt.
