Definitions

  • the present invention relates to explosive compositions of the water-in-oil emulsion type, their manufacturing process and their application.
  • Another means, of more recent origin, consists in producing a much more intimate mixture between the solution of oxidizing nitrates and the fuel oil by combining them in the form of an emulsion.
  • an aqueous solution of the oxidizer is emulsified in the form of a dispersed phase inside a continuous carbonaceous combustible phase; a lightening constituent introduced in the form of mechanically included air, either in the form of a gas obtained by chemical means, or also in the form of microbubbles either spherical of the "microballoon" type, or in any form such as perlites, polyurethane, polyvinylidene chloride or expanded polystyrene is necessary to adjust the density and ensure sensitization in diameters which can be greatly reduced (of the order of 30 mm and less).
  • Patents US-A-3,447,978.4,008 108.4 110 134.4138,281 and 4,141,767, EP-A-0,019,458, DE-A-235,005 and BE-A-881,116 and 880,736 describe genre of compositions; numerous patents specify the nature of the oxidizer (s) used, that of the combustible oily phase, as well as that of the emulsifiers and gaseous constituents used.
  • an explosive emulsion consists of approximately 93 to 97% of an emulsified gel (in which 5 to 15 parts of water enter, 70 to 80 parts of one or more salts oxidizing minerals, 3 to 6 parts of combustible oil and possibly wax and 1 to 2 parts of emulsifier), to which approximately 3 to 7% of lightening material is added.
  • Document EP-A-18 085 discloses an explosive composition of the water-in-oil emulsion type comprising an emulsified gel, an inert lightening component and NaCl in an amount of 25%.
  • the emulsified gel consists of a solution of NH 4 N0 3 in water, an oily phase and an emulsifier.
  • the present invention relates firstly to an explosive composition of the water-in-oil emulsion type, comprising at least one emulsified gel, consisting of an oxidizing solution obtained from at least one mineral salt dissolved in water and d '' a combustible phase containing at least one liquid hydrocarbon and an emulsifier, associated with a lightening constituent, inert or reactive and, optionally, with one or more oxidizing salts or metallic fuels and / or inert materials, characterized in that '' it contains from 4 to 55% of inert or semi-inert solid materials which are silicates or diatomaceous earths or a mixture of the two at a rate of 1 to 4 parts of the former and 0 to 7 parts of the latter, depending on the degree of plasticity that we want to obtain.
  • emulsified gel consisting of an oxidizing solution obtained from at least one mineral salt dissolved in water and d '' a combustible phase containing at least one liquid hydro
  • inert and "semi-inert” must be understood in their acceptance of the technique of explosives. Mixtures of emulsified gel with inert or semi-inert materials, in proportions ranging from 96/4 to 45/55, always constitute true explosives whose detonation is complete and normal for as much as they contain the usual lightening component for water-in-oil type emulsions regulating their density and sensitization.
  • the safety character is obtained by the fact that the intervention of inert or semi-inert materials within the emulsified and aerated gel is marked by a reduction in its detonation speed (the latter being able to be adjusted to values less than 2000 m / s), and its energy potential, which are just as many fundamental factors in regulating the safety of an explosive.
  • the compositions comprise additions of inert materials from the family of chlorides or alkaline bicarbonates up to 10 to 45%, which makes it possible to obtain sureties such as those defined above, the salts to be taken into consideration being, inter alia, NaCI or NaHC0 3 .
  • This inert material can in particular be, in the case where it is desired to ensure safety of the P5 type, NaCl, with a particle size 250 to 500 microns and preferably at a content of 10 to 45%.
  • the inert material can be a premix of NaCl with a particle size of 250 to 500 microns, of calcium silicate and of diatomaceous earth, with a preferential content of 17 to 45%, comprising 15 to 38 parts of NaCl, 1 to 4 parts of calcium silicate and 0 to 7 parts of diatomaceous earth, which ensures both PS type security and paper cartridge filling on a conventional machine.
  • a semi-inert material which is a premix of N0 3 Na or N0 3 K, of which 80 to 90% of the grains are between 53 and 125 microns, and of NH 4 CI of which 50% of the grains are larger than 200 microns, calcium silicate and diatomaceous earth, at a content advantageously between 25 and 43%, comprising 11 to 24 parts of N0 3 Na or NO 3 K, 7 to 15 parts of NH 4 CI, 1 to 2 parts of silicate and 4 to 5 parts of diatomaceous earth, ensuring both P5 type safety and cartridge filling on a conventional machine.
  • part of the inert materials is calcium silicate, preferably of the silene or Calflo types and the diatomaceous earth is of the hyflosupersel type.
  • the lightening agent must have an apparent density of less than 30 g / liter; the one that has given the best results so far is expanded polystyrene at 18 g / liter.
  • an additional supply of oxygen must be provided to the composition by adding one or more inorganic oxidants.
  • This oxidant can be an inorganic nitrate, preferably of high molecular weight, optionally combined with an inorganic perchlorate.
  • inert materials the content of which remains between the limits already defined (from 4 to 55%), they consist essentially of extinguishing salts (NaCI for example) and sand.
  • NaCI extinguishing salts
  • the base gel content can be limited to 25 - 30% of the final composition.
  • the emulsion containing the lightening agent could be made extrudable on the cutting machine, without enjoying any kind of safety in the presence of an explosive gas atmosphere.
  • inert materials in the case where 10% of inert materials are used, it will be a premix comprising 2.5 to 3% of calcium silicate and 7.5 to 7% of diatomaceous earth; in the case where it is desired to use for example 45% of inert materials, it will be a premix consisting of 2.5 to 6% of silicate, 7.5 to 14% of diatomaceous earth and 25 to 35% of sand.
  • the diatomaceous earths could be replaced by hydrophobic, non-inert materials, such as calcium stearate; for this purpose, it is preferable to combine 1 to 3 parts of the latter with 3 to 7 parts of silicate; unlike the other additive materials taken into account until now, it is necessary to take into account in the calculation of the thermodynamic balance of the explosive of the fact that the stearates have an energy potential which takes part in the primary reaction of detonation.
  • Inert or semi-inert materials used both for extrusion and for safety in an explosive atmosphere, are, in the form of a premix, fed by means of a metering device into a continuous or discontinuous mixer, or they meet either the gel hot leaving the foaming device and the lightening component (continuous process) or a cold gel having already undergone a certain storage to which is also added the lightening component.
  • the finished product is poured or pumped onto the conveyor belt of the cartoning machine; if a hot gel is used, this strip must be cooled so that the temperature does not exceed approximately 40 ° C at the time of cutting.
  • the invention extends to the application of the explosive compositions of the invention having either a safety character with respect to the atmospheres encountered in coal mines, or the ability to be paper cartridges on a machine of the type classic, that is to say these two properties at the same time, while preserving with the explosive, even in small diameter of the normal characteristics of detonation.
  • the gel prepared at 75 ° C consists of:
  • 50% of the emulsified gel (hot or cooled) is mixed with 45% NaCl and 5% microbeads of type C15 - 250; NaCI is of a type whose particle size is between 250 and 500 microns.
  • Its safety is of the P5 type, it is not intended for extrusion on a Rollex machine, but it can be carted in plastic sheath on a Chub-Pack machine.
  • Example 1 50% of the emulsified gel of Example 1 is mixed with 45% of a premix consisting of 38 parts of NaCl and 7 parts of guhr and with 5% of Microbeads C15 - 250.
  • the explosive emulsion is such that it has both the safety characteristics of a P5 type explosive and the property of being paper-insertable on the cutting machine; in 30 mm, the density is 1.15 and the speed at detonator No. 8 is 2870 m / s for the fresh explosive; after 3 months, the speed is 2700 m / s.
  • the critical diameter of such a composition is between 10 and 15 mm; in diameter 15 mm, the speed is 2300 m / s. In ballistic mortar, the relative power is 20.8% of that of blasting gelatin.
  • the characteristics of the explosive emulsion of Example 2 do not change, but the extrudability is even better if the 7% of guhr is replaced by a mixture comprising 2% of calcium silicate, of type Silene or Calflo and 5% of diatomaceous earth of the Hyflosupersel type.
