  • Patent number: 10309202
    Abstract: Applying shock waves using a plasma pulse generation system or other comparable systems, including an acoustic/pressure oscillatory system, would help to enhance the complexity of the far field hydraulic fracture during fracturing shale formation. It would also help in avoiding pre-mature screen out. The critical factor to maximize the desired results is to apply the shock waves at the correct time. By combining shock wave technology with the newly developed fracturing pressure data analysis, it is possible to achieve maximum results.

  • Patent number: 10267608
    Abstract: Munitions structures comprising one or more high strength reactive alloys, in particular reactive bulk metallic glasses, have significant amounts of inherent chemical energy. This energy may be discharged by subjection of the munitions structure to rapid impulsive loading and fragmentation in the presence of oxygen and/or nitrogen. A munitions structure can be configured in both large and small penetrators, e.g. warheads and bullets, with increased lethality. The lethality of these munitions structures is augmented by means of rapidly and simultaneously imparting both mechanical energy (kinetic energy through impact and fragmentation) and chemical energy (blast and/or fireball) to a target. A high-strength reactive alloy can substitute at least in part one or both of explosives and inert structural materials in conventional munitions systems to improve performance and reduce parasitic weight of structural casing.

The method involves providing each blast hole in a drill pattern with an individually identifiable first identifier and a GPS device capable of relaying identification and location data for the respective blast hole. A data reception system is provided to receive the data and store it in a database for processing purposes. The information may be later used to correlate any one or more of the blast holes with a corresponding detonator.

  • Publication number: 20120192749
    Abstract: A method for minimizing the carry-off of entrained airborne material and an apparatus for carrying out the method are provided that are particularly suitable for deployment in an open pit mining operation in which cyclic blasting operations create debris that, by virtue of its very small (particle) size and weight, is susceptible to being carried beyond the open pit mining location and deposited in adjacent communities. The method and apparatus of the present invention beneficially minimize the “carry-off” risk of such debris without substantially interfering with the blasting and material handling and transport operations of an open pit mining operation.

  • Patent number: 8119958
    Abstract: A matrix of explosive cells can include plural explosive cells formed in an array in a common substrate. Each cell can be formed as a recess filled with explosive material. An ignition device has an addressable ignition source for each cell. This matrix can be used in combination with a projectile guidance system. The projectile guidance system includes an antenna, a transceiver and a control processor. A method of guiding a projectile can include firing a projectile at a target, tracking the projectile and the target, determining a desired change in a flight path of the projectile, transmitting guidance commands to effect the desired change in the projectile's flight path to the projectile, receiving the guidance commands onboard the projectile and selectively igniting an explosive cell in a matrix of addressable explosive cells contained in a common substrate using the guidance commands.

  • Patent number: 8099240
    Abstract: Methods for evaluating drill pattern parameters such as burden, spacing, borehole diameter, etc., at a blast site are disclosed. One method involves accumulating the burden contributed by successive layers of rock and matching the accumulated rock burden to a target value for a borehole having a length related to the average height of the layers. Another method relates to varying drill pattern parameters and characteristics to match blast design constraints, including the substitution of one explosive material for another by the proper balance of materials and/or output energies to the associated rock burden. Analysis of deviations from target rock burdens and corrective measures are disclosed, as well as cost optimization methods. The various methods can be practiced using an appropriately programmed general purpose computer.

  • Publication number: 20110005422
    Abstract: A method and apparatus for cooling a planet uses an explosion to lift a dust cloud into the atmosphere. The dust cloud shields the surface of the planet from some sunlight. One aspect of the invention relates to detonating an explosive to generate a dust cloud and to create an updraft to lift the dust cloud into the atmosphere where it can be spread by winds over the area to be cooled. The dust in the atmosphere blocks sunlight from reaching the surface, allowing the planet to cool. Multiple explosions at multiple locations or at the same location may be use for greater cooling. Explosions may be caused by nuclear weapons or by the impact of an asteroid or comet.

  • Patent number: 7819063
    Abstract: A breaching device for positioning explosives on a structure for rapid entry constructed of soft, plastic material formed into elongated inflatable chambers allowing the breaching device to be positioned by secondary attachment means to a target surface. A sleeve is formed on the chamber for insertion of an explosive material thereby reducing the need for supplemental construction materials for the device. The rigidity of the inflated device is achieved by inflation so as to hold its shape and be semi self-supporting and to increase the ease to which the device can be deployed. By utilizing a device which will hold its specific shape and precise positioning of explosives therewithin will insure that the explosive force of detonation will be applied directly to the structure and the desired shape, size and amount for breaching a structure for entry.
