Patent number: 11209250Abstract: The present invention relates to a device, a system and a method for retaining detonators in an explosive booster, particularly a retention device for retaining a detonator in the blind hole of a booster which allows the safe extraction thereof from the booster. The retention device comprises a flexible holding means that is movable between a blocking position retaining the detonator inside the blind hole and an open position which allows extracting the detonator from the blind hole.Type: GrantFiled: April 17, 2018Date of Patent: December 28, 2021Assignee: MAXAMCORP HOLDING, S.L.Inventors: José Zuriaga Gascón, José Luis de Miguel Fuentes

Patent number: 10793485Abstract: The present invention relates to a water-based non-sensitized matrix or explosive suspension which itself has a rheological behavior such that it allows mechanically loading upward boreholes. This suspension behaves like a viscous liquid when it is forced to flow due to the action of a loading pump, and, however, has the characteristics of a soft solid when it is on standby once inside the borehole. The composition essentially consists of an aqueous solution of oxidizing salts and optionally water-soluble fuels and/or sensitizers, and one or more water-soluble polymers conferring the desired rheological characteristics. Particles of oxidizing salts with a grain size such that they enhance the rheological behavior characteristic of the suspension are dispersed in this aqueous solution.Type: GrantFiled: February 9, 2016Date of Patent: October 6, 2020Assignee: MAXAMCORP HOLDING, S.L.Inventors: José Ramón Quintana Angulo, Arturo Carranza Vítores

Patent number: 10532959Abstract: Manufacture is carried out in a continuous manner while simultaneously loading the blast holes in a device with mixing capability where (a) a less sensitive or non-explosive water-based matrix containing a cross-linkable polymer, (b) a cross-linking agent for cross-linking the polymer contained in the matrix, (c) a gas-generating agent, are mixed. The presence of the polymer distributed uniformly in the matrix together with the cross-linking agent results in a three-dimensional network formed by molecular polymer chains bound to one another in a short period of time after mixing. The process can be performed in trucks for loading explosives in blast holes having compartments for the different components of the mixture and one or several mixing devices allowing the manufacture of the final mixture which would be unloaded into the blast holes either by means of a pump or an auger.Type: GrantFiled: March 27, 2014Date of Patent: January 14, 2020Assignee: MAXAMCORP HOLDINGS, S.LInventors: Jose Ramon Quintana Angulo, Fernando Beitia Gomez De Segura, Arturo Carranza Vitores

Systems and methods for chemical and/or mechanical remediation of nitro compounds and nitrate esters
Patent number: 8585841Abstract: Systems and methods for chemoremediation or mechanical destruction of undetonated explosive materials. An explosive apparatus contains an explosive material in close proximity to a chemical reagent selected for its chemoremediative properties. A barrier is interposed between the explosive material and the chemical reagent to delay the chemoremediation of the explosive material. Alternatively a water expandable material may be incorporated into the explosive material, whereby upon exposure to moisture the water absorbing material will expand sufficiently to fragment the explosive material into initiation insensitive particles. Initiation insensitivity is achieved by incorporation of water, which acts as a desensitizing agent as well as fragmenting the explosive material into particles sufficiently small that they are below the critical diameter for explosive initiation.Type: GrantFiled: June 24, 2010Date of Patent: November 19, 2013Assignee: MaxamCorp Holding S.L.Inventors: Carl Hermanus Lubbe, Delana Harris, José Manuel Botija González, Fernando María Beitia Gómez De Segura -
