摘要： An inflatable air tube includes a sleeve member arranged concentrically about the upper end portion of the air tube to define a receptacle chamber for receiving a quantity of bulk explosive blasting powder, thereby to add weight to the air tube for positioning and stabilizing the same in the bulk explosive powder during the depositing of the powder into a blasting hole drilled into the ground. According to the method of the present invention, a plurality of accurate blasting patterns may be provided in the blasting powder column by timing the manual or mechanical insertion of the air tubes into the bulk blasting powder relative to the rate of supply of the powder from a source thereof.

摘要： Rock and other hard materials, such as concrete, are fragmented by a controlled small-charge blasting process. A cartridge containing an explosive charge is inserted at the bottom of a hole drilled in the rock. The explosive charge is configured to provide the desired pressure in the hole bottom, including, if desired, a strong shock spike at the hole bottom to enhance microfracturing. The cartridge is held in place or stemmed by a massive stemming bar of high-strength material such as steel which blocks the flow of gas up the drill hole except for a small leak path between the stemming bar and the drill hole walls. The cartridge-incorporates additional internal volume designed to control the application of pressure in the bottom hole volume by the detonating explosive.

摘要： The present invention is directed to a method for breaking rock and other hard materials using small-charge blasting techniques followed by a mechanical impact breaker. In small-charge blasting techniques, a gas is released into the bottom of a sealed hole located in a free surface of the hard material. The gas pressure rises rapidly in the hole until the gas pressure causes the hard material to fracture. The impact breaker is then used to complete fracturing of the material and to remove the fractured material.

摘要： A borehole decking plug which is created by a self-expanding plastic foam. Two closed waterproof pouches, an inner pouch and an outer pouch, each contain a separate component of the foam. The inner pouch is contained within the outer pouch, and both are contained within a third open external pouch having a tether attachment. Upon breaking the inner pouch, the separate foam components combine within the outer pouch to form a complete expansion foam. The foam expands slowly enough to provide sufficient time for the device to be lowered via the tether down a borehole to a preselected position. Once in position, the expansion foam bursts the outer pouch and escapes upward through the external pouch to form a deck plug at the preselected position.

摘要： The invention is a lid for a shaped charge which enables application of torque to the shaped charge for mounting in an expendable bar carrier borehole penetrating gun assembly. The lid comprises a plurality of flat surfaces facially parallel with the axis of a threaded stud forming part of the lid, the stud engaging mating threads in a hole in the carrier. The flat surfaces are arranged around the circumference of the lid so that a wrench or socket can be used to apply torque to the lid for mounting in the carrier. Each juncture of two contiguous ones of the flat surfaces includes a score line extending substantially perpendicular to the axis of the stud.In a preferred embodiment of the invention each juncture includes a crimp on part of the juncture on a side of the score line opposite to the stud, to retain the lid on the charge.The invention is also an apparatus for simultaneously torquing a plurality of shaped charged in a bar carrier. Each of the shaped charges comprises the charge lid of the invention. The apparatus includes a plurality of wrench sockets, corresponding final drives coupled to the sockets, an intermediate drive coupled to all of the final drives, and a motor to turn the intermediate drive, all mounted in a frame. The final drives are coupled to the intermediate drive to cause all the sockets to rotate in the same direction. Positioning the frame to enable the sockets each to engage a shaped charge will cause all the charges to be torqued simultaneously.

摘要： A method and apparatus are described for feeding a hose having a corrugated exterior surface into a mining borehole and the like. The apparatus includes a support frame and a rotatable drive wheel having an annular groove for receiving the hose and ridges extending therefrom for meshing with the corrugated surface of the hose. An idler wheel having an annular groove for receiving the hose is disposed on the support frame to bias the hose against the drive wheel. A reversible, variable speed motor coupled to the drive wheel is provided for causing the drive wheel to rotate in a selectable direction and at a selectable speed. The apparatus is mountable on an implement used in a mining operation. The hose is couplable to a source of liquid explosive and to an inflatable wand for charging boreholes with explosive.

摘要： Hard compact materials, such as rock, concrete, et cetera, are broken by igniting an appropriately designed explosive or propellant charge placed within the hole or carried in a special charge-containing device with a short barrel which is inserted and sealed into a pre-drilled hole of particular geometry. One or more approximately cylindrical holes are drilled into the material to be broken by conventional drilling, such as used in the mining and construction industries. The holes have a relatively short depth to diameter ratio, being in the range of about 2:1 to 6:1, and preferably about 3:1 to 5:1. The holes are percussively drilled with microfractures in and around hole bottoms to provide fracture initiation sites at the hole bottoms so as to provide preferred fracture initiation roughly parallel to a free surface of material being excavated. The explosive or propellant charges may be any of several commercially available explosives or propellants, including standard military and commercial rifle powders and various recently developed liquid propellants. The propellant charges, whether solid or liquid, may be placed and ignited within a charge-containing device, which includes a short barrel inserted into the holes drilled into the material to be broken. The barrel of this device may be further sealed into the holes by a helical shim sealing method.
