  • Patent number: 10213813
    Abstract: A method and cleaning device for removing deposits from interiors of receptacles and installations by way of explosion technology. The cleaning device includes a cleaning apparatus with a receiving space, and at least one pressure container that is connected via at least one metering fitting to the cleaning apparatus. The controlled introduction of the at least one gaseous component into the cleaning apparatus is effected according to the principle of the differential pressure between a maximal pressure at the beginning of the introduction and a nominal residual pressure after completion of the introduction. For this, based on a maximal pressure, the nominal residual pressure in the pressure container is ascertained on the basis of the quantity of gaseous component to be introduced, and the introduction of the at least one gaseous component is stopped on reaching the nominal residual pressure, which thereby lies in the overpressure range.

  • Patent number: 7707938
    Abstract: At least two gases combine to form a detonable mixture that is detonated near an avalanche start zone. Each gas is separately supplied at a pressure above ambient pressure so that the pressure differential drives the gases through a mixer and to deploy as a detonable cloud in open air near the start zone. An igniter is located in communication with the detonable cloud near its discharge point from the mixer so that the igniter will be in communication with the cloud near the end of a predictable time interval. A controller releases the gases to initiate the mixing and deployment of the gas cloud and measures the interval. At the end of the predictable time interval, the controller fires the igniter to detonate the explosive gas mixture in open air.

  • Patent number: 6460462
    Abstract: A method of blasting rock or similar materials in surface and underground mining operations is described in which neighboring bore holes are charged with explosives and primed with detonators. The detonators are programmed with respective delay intervals according to the firing pattern and the mineralogical/geological environment and the resulting seismic velocities.

  • Patent number: 6438191
    Abstract: A new approach to scabbling of surfaces of structural materials is disclosed. A layer of mildly energetic explosive composition is applied to the surface to be scabbled. The explosive composition is then detonated, rubbleizing the surface. Explosive compositions used must sustain a detonation front along the surface to which it is applied and conform closely to the surface being scabbled. Suitable explosive compositions exist which are stable under handling, easy to apply, easy to transport, have limited toxicity, and can be reliably detonated using conventional techniques.

  • Patent number: 6431075
    Abstract: Disclosed herein is a center-cut blasting method for tunnel excavation. The center-cut blasting method includes the step of drilling a single central center-cut hole at the center of a center-cut region, drilling a plurality of auxiliary center-cut holes comprised of large unloaded auxiliary holes and loaded auxiliary holes that are alternately arranged around the central center-cut hole to be situated in a circle having a predetermined diameter, and drilling a plurality of spreader center-cut holes outside the auxiliary center-cut holes to be situated in concentric circles centered by the central center-cut hole. Thereafter, the center-cut holes are loaded with delay detonators and explosives and the center-cut holes are stemmed with stemming material at their entrances. The loaded auxiliary holes of the auxiliary center-cut holes are blasted so as to create a circular pre-split. After that, the central center-cut hole is blasted so as to create initial dual free surfaces.

  • Patent number: 6431074
    Abstract: Supplying a predetermined amount of electric energy to a fine metal wire 4 in a short time causes the fine metal wire 4 to melt and evaporate. Following this phenomenon, a blasting substance 10 expands in volume, so that the evaporative expansion force resulting from the melting evaporation of the fine metal wire 4 is transmitted to and blasts a to-be-blasted object 5.

  • Patent number: 6431073
    Abstract: A device, system and method permitting on-line explosives-based cleaning and deslagging of a fuel burning facility (31) such as a boiler, furnace, incinerator, or scrubber. A coolant, such as ordinary water, is delivered to the explosives (101) to prevent them from detonating due to the heat of the on-line facility. Thus, controlled, appropriately-timed detonation can be initiated as desired, and boiler scale and slag is removed without the need to shut down or cool down the facility.

  • Patent number: 6415716
    Abstract: A line charge assembly and system are provided for use in a shallow-water obstruction clearing operation. Each assembly has a propulsion unit capable of flight through the air, a line charge array, an air-safed water-armed fuze, and at least one explosive diode. The line charge array is defined by a plurality of line charges successively coupled to one another by a line capable of transferring detonation energy therealong successively to each of the line charges. One end of the line charge array is coupled to the propulsion unit and the other end is coupled to the fuze. The fuze is capable of generating the detonation energy only when in water. The explosive diode is positioned in the line charge array to limit transfer of the detonation energy in a direction of propagation running from the fuze to the propulsion unit. The system utilizes a plurality of the line charge assemblies deployed over an area.

  • Patent number: 6415717
    Abstract: A line charge assembly and system are provided for use in a shallow-water obstruction clearing operation. Each assembly has a propulsion unit capable of flight through the air, a line charge array, an air-safed water-armed fuze, a first interrupter disposed between the line charge array and the fuze, and a second interrupter disposed in the line charge array. The line charge array is defined by a plurality of line charges successively coupled to one another by a detonation line capable of transferring detonation energy therealong successively to each line charge. The line charge array has a first end coupled to the propulsion unit and has a second end coupled to the first interrupter. The fuze generates the detonation energy at the expiration of a first time period provided the fuse is in water. The first interrupter permits the detonation energy to be transferred from the fuze to the second end of the line charge array until the expiration of a second time period.

  • Patent number: 6408761
    Abstract: A melting/vaporization substance 2 is melted and vaporized by supplying an electric energy of a predetermined amount from an electric energy supply circuit to the melting/vaporization substance 2. An explosive blasting substance 3 is exploded by a phenomenon caused in a process of melting and vaporization of the melting/vaporization substance 2, so that a to-be-blasted object 4 is blasted by that explosive force.

  • Patent number: 6374717
    Abstract: The invention concerns a device (10) for provoking an avalanche comprising a gas gun (12) the end of which is fixed to a seat (13) solidly anchored to the mountain and the downstream end of which is born by at least one leg (14) such that the mouth of the gun is arranged above the snow cover. The gun (1q2) upstream end is fixed to the seat (13) by an articulation (17), and the downstream end is ballasted, the leg (14) being mounted freely on a base (15) made integral with the ground. The leg (14) is hollow and contains ballast consisting of chippings or concrete. The gun (12) is further provided with ignition mechanisms (54) arranged upstream in its proximity and ensures the ignition of the detonating gas mixture.
