  • Apparatus, system and method for initiation of buried explosives
    Patent number: 10113843
    Abstract: An initiator apparatus (IA) for blasting, the apparatus including: a magnetic receiver for receiving a magnetic communication signal through the ground by detection of a magnetic field; a controller, in electrical communication with the magnetic receiver, for processing the magnetic communication signal to determine a command for blasting; and a light source in electrical communication with the controller for generating a light beam to initiate a light-sensitive explosive (LSE) in accordance with the command.
    Type: Grant
    Filed: March 23, 2015
    Date of Patent: October 30, 2018
    Assignee: Orica International Pte Ltd
    Inventors: Rodney Appleby, David Johnson, Richard Goodridge, Byron Wicks
  • Explosive composition
    Patent number: 10081579
    Abstract: An explosive composition comprising a liquid energetic material and sensitizing voids, wherein the sensitizing voids are present in the liquid energetic material with a non-random distribution, wherein the liquid energetic material comprises (a) regions in which the sensitizing voids are sufficiently concentrated to render those regions detonable and (b) regions in which the sensitizing voids are not so concentrated and wherein the explosive composition does not contain ammonium nitrate prill.
    Type: Grant
    Filed: December 13, 2012
    Date of Patent: September 25, 2018
    Assignee: ORICA INTERNATIONAL PTE LTD
    Inventors: John Cooper, Ian John Kirby, Richard Goodridge, Vladimir Sujansky, Simon James Ferguson
  • Microbial deactivation of explosive compositions
    Patent number: 9814918
    Abstract: A method of deactivating an explosive composition being used in a blasting operation, which method comprises exposing the explosive composition to a micro-organism that is indigenous to the environment in which the explosive composition is being used and that is capable of producing an enzyme that degrades the explosive composition, wherein the explosive composition has associated with it a chemical inducing agent that promotes production of the enzyme by the micro-organism.
