Abstract: A component and method for evaluating load at a mine roof. An embossed bearing plate and a reinforcing washer are combined to thereby form a bearing system, wherein the bearing plate is a grade 2 plate (“x?1”), the bearing plate including a back surface which is adapted to contact a mine roof, an opposite surface and an aperture through which a shaft portion of a bolt can extend, the reinforcing washer including a rigid member having a first surface shaped to contact and complement the opposite surface of the bearing plate, a second opposing surface and a washer hole for alignment with the aperture through which the shaft can extend; driving a bolt with the shaft through the bearing system into a location of the mine roof, and, inspecting a curl of the grade 2 plate, wherein the curl and uniformity thereof is indicative of a load of around 20,000 pounds at the location.

Abstract: A ground-disposed foundation mat. A pre-drilled, wooden block has a thru-hole, the thru-hole defined by a thru-hole inner surface and a hole diameter, the wooden block having an outer surface; a rod is power-driven through the thru-hole, the rod having a head top surface and a smooth outer surface, the rod having a lead end, the rod having an outer diameter equal to or slightly greater than the hole diameter of each of the thru holes, wherein each rod is held in place by significant friction between the thru-hole inner surface and the smooth outer surface of the rod. As such, the rod is adapted to remain held in place within the block even when subjected to a pull force of at least 3 tons.

Abstract: A mining bolt system to anchor mining roofs. A bearing plate has a top bearing surface, a bottom bearing surface and a central hole. An L-shaped angle bracket having an upstanding portion and an upper portion has further defined therein a pair of bracket holes. A bolt including a rod portion and a bolt head passes through the central hole and into a mine roof. A threaded staff is then adapted to pass through one of the bracket holes underneath the bottom bearing surface, wherein, in combination, the bearing plate, angle bracket and threaded staff can be tensioned to provide a lifting force against the mine roof.

Abstract: A nut to be used as part of a fastener to be used in multiple ways in various industries or methods has a drive mechanism and stud extending from the drive mechanism with a threaded bore. In addition the nut can be specifically used as a method and as part of special fastener that can be used to join cut, hard-wood members, other naturally occurring manufactured mat members or synthetically man made members, referred to as “timber(s)” or “laminated”, in forming a mat used for heavy construction equipment to run on over ground which is not stable. These mats are commonly referred to as “Crane Mats” or “Laminated Mats” in the construction, mining, pipeline, and oil and gas industries among others.

Abstract: A cuttable, sinkable mining bolt system for use in supporting the sidewall or rib in a coal mine. A bearing plate has a plurality of hollow cores defined transaxially therein and a central hole defined axially therethrough, the bearing plate made of modified recycled, rigid PVC compound. A fiberglass bolt is adapted to be inserted through the central hole of bearing plate. Bolt is one-piece consisting of glass fiber reinforced plastic. Head component includes a square head and integral, beveled washer for self-centering in the bearing plate as rod component is driven into rib. Bearing plates are adapted to sink into a refuse stream. Hollow cores of bearing plate reduce the material and thus the weight and expense of the bearing plate while still allowing the bearing plates to sink. Optionally, rod components can be inserted transaxially through the hollow cores to increase the strength and coverage of the system.

Abstract: An assembly method and resulting temporary foundation mat for equipment such as a crane, including the steps of driving a fastener through plastic either with a hydraulic force or pneumatic (air), mechanical, or by any other power assisted means, shown through experimentation to result in the plastic surrounding the bolt within itself, tightly giving added strength to the system. The fastener can have a head at the driven end and a threaded end at the lead end. When a threaded end exists exterior to the joined pieces of plank, the plastic around the threaded end can be power-wire brushed to expose the threads to a nut which then tightens the system. The penetration rate of the fastener into and through the plastic pieces can be increased by pre-heating the lead end of the fastener.

Abstract: This new system can utilize a threaded bolt head on one end of a roof bolt and an anchoring device on the other end of the bolt. The roof bolt is designed in such a manner to allow the bolt head to drive the bolt for anchoring purposes and to allow the bolt head to also serve as the attachment mechanism for ancillary appendages. This system can be utilized as the primary roof bolting system, or, as an ancillary system in conjunction with existing primary roof bolts.

Abstract: 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.
