The fastener clip comprises a base member adapted for secure mounting to the side wall and a pair of spaced resilient parallel legs projecting outwardly from the base member generally perpendicularly to the side wall. The gap between the parallel legs is generally parallel to the installed position of the plate-like member. A head is formed on the end of each leg, extending generally away from the gap. Each of the heads has at least a first inclined surface, with the first inclined surfaces oriented with respect to each other so as to form a generally "V" shaped channel for guiding the leading edge and bead of the plate-like member into the space between the parallel legs.

Abstract: In this invention there is taught the use of air tubes or fluid-filled containers to define permanent hollow tubular space within a body of solidified fill material placed in a mining excavation. The fill uses a mixture of solids and liquids with the addition of a structurally binding substance such as cement in order to make the fill substance permanent and capable of providing structural integrity and strength in the fill notwithstanding the empty tubular space. The empty tubular space can be used in accessways for mining and hauling of ore, or ventilation; it can also be used to provide volume within which to place fine component of tailings of a concentrator, or to store contaminants, or to route fill material. The tubular empty space within the fill reduces the weight, time and cost of the fill operation, and eliminates the need to drive galleries in waste rock, or of constructing costly timbered galleries or steel tubes within the stope prior to backfilling with tails.

Abstract: A method of reconstructing or reclaiming river channels which are partially filled with soft, slimy sedimentary deposits including industrial wastes which are in a semi-fluid condition or fluidized state comprising the steps of: demarcating a portion of the channel by placing a water tight wall entirely across the channel from bank to bank at an upstream and downstream location; depositing stable fill material adjacent the banks of the channel so as to displace the soft sedimentary deposits and water toward the center of the channel; and treating the displaced soft sedimentary deposit in situ beneath the overlying water so as to stabilize the entire mass.The channel may be completely reclaimed by pumping out the overlying water after the soft sedimentary deposit has been stabilized and then filling with stable material or stable material may be simply placed on the stabilized mass and the water displaced over the top of the downstream wall or over the adjacent bank.

Abstract: A method and the apparatus for implementing the method to provide temporary ground support in a mine. After an auger or other type of hole has been bored in an underground mine, at least one inflatable bladder with a fluid conduit therethrough is inserted into the hole. Once the bladder is inflated it expands to fill the hole's diameter and to act as a plug. Thereafter, fluid is forced through the fluid conduit past the bladder and into the hole cavity to act in conjunction with the bladder as a ground support for the hole. Appropriate fluid valves, meters, and conduits are placed at the input to the fluid conduit to control and measure the fluid being forced into the bladder and the hole cavity. Quick connect-disconnect couplings are provided when two or more bladders are connected seriatim and placed within the hole.
