摘要： A support sling, useful in the mining industry, for example, for supporting overhead loads such as mine roofs; the sling includes a pair of generally coplanar anchor lengths, sometimes called anchor bolts, having inwardly directed ends mutually facing each other and which, thus, are essentially coaxial; a similarly coaxial take-up coupling structure secures the ends and is constructed, either in active or passive mode, to restrain loads, acting under the force of gravity, from dilating downwardly to extreme conditions, and this in a manner as not to allow for the generation of serious force couples in the sling.

摘要： An elongated channel member 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 member 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 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.
摘要翻译：用于支撑地下岩层表面的细长通道构件包括具有用于接触岩层的支承表面的底部部分和具有纵向延伸的中心肋和法兰边缘的相对表面，用于抵抗通道构件的下面的偏转和弯曲岩层的载荷。间隔开预定距离的多个开口延伸穿过中央肋。支承板与通道构件中的每个开口相邻地邻接地定位。轴承板包括压花区域和纵向凸缘边缘，该边缘的形状与中心肋和通道上的凸缘互补，以牢固地接合通道构件上的支承板。因此，支承板与通道构件接合，以限制支承板在通道构件上的纵向和横向移动并加强通道构件以抵抗弯曲。锚定螺栓延伸穿过支承板和通道构件中的对齐的开口进入在岩层中钻出的钻孔中。锚定孔中的螺栓将支承板压靠在通道构件上，以迫使通道构件与岩层的表面压缩关系以支撑岩层。

摘要： A mine roof support system is disclosed having a connector. The connector has a first hole through which one end of a first roof supporting rod is inserted and a second hole through which one end of a second roof supporting rod is inserted. The first and second roof supporting rods are fastened to the connector so as to support the roof of the mine. In order to increase the bending arcs of the connector along which the first and second roof supporting rods bend without increasing the weight of the connector, the holes of the connector may be bevelled to form elliptical openings in the connector and the connector may be canted.

摘要： A truss structure, components, and method for trussing arched roofs in mines and the like. The truss structure includes, in addition to specially designed brackets and tensioned elongate connectors, one or more medially positioned upstanding post brackets for upwardly abuting against central portions of an arched mine roof. The method and concept includes, in a preferred form, applying obtuse-angle-oriented elongate connectors such as tie rods, secured to a lower portion of a post bracket concerned such that, when said elongate connectors are tensioned, an upward thrust is applied to said post brackets, whereby to produce an increased compression zone in the roof rock above the arched roof. Like-constructed interlocking roof truss structures are also provided for both longitudinally and also tranversely trussing an arched mine roof.

摘要： Structure and method for deterring cutter roof failure in underground mines such as coal mines. An elemental device of such structure comprises a unique bracket accommodating angulated bolting and having end-apertured flanges suitable for accommodating mutually horizontal tie rods disposed in tension. A series of the bracket devices are mutually spaced end-to-end and are longitudinally aligned parallel and generally proximate to a rib-roof juncture. Connecting tie rods intercoupling the bracket devices, are disposed in tension and, because of such, the roof strata proximate the roof-rib edge is placed longitudinally in compression. Truss support structures incorporating a plurality of devices can be made up to support and place in compression in large roof areas to deter roof failure. The method involved, for deterring cutter roof failure, is to provide, in one form of the invention, the said bracket devices and then anchoring the same over, e.g., the pillar areas and joining the bracket devices together lying essentially parallel to rib-roof junctures along an elongate path.

摘要： A reinforcing and or confining structure for an earth formation comprising a plurality of anchor members anchored at spaced intervals in an earth formation, the anchor members being connected to the adjacent anchor members by tensile members to form a substantially continuous tensile member adjacent the surface of the ground formation. Point loads resulting from earth movements are dissipated as a tensile load throughout the system. The anchor members may be tensionable to reinforce the earth formation. The tensile elements may be formed integrally with the anchor members in a substantially L-shaped configuration or they may be separate therefrom. The substantially continuous tensile members may be formed in spaced parallel rows or they may overlap or be interconnected to form a mesh-like structure.

摘要： A drilling tool for drilling a cylindrical borehole of relatively great depth in a soft material and then forming a conical enlargement adjacent the bottom of the borehole includes an axially elongated tool shank with a first drill at one end for cutting the cylindrical borehole and a second drill adjacent the first drill for cutting the conical enlargement. The second drill is formed of bit holders pivotally connected to a flattened part of the tool shank. An adjustable stop is provided on the tool shank for determining the depth of the borehole. A connecting link guide located within the tool shank interengages the bit holders and the tool shank. When the desired depth is reached, due to relative axial displacement between the tool shank and the connecting link guide, the bit holders are pivoted outwardly so that the second drill can cut the conical enlargement.
