Definitions
- the invention relates to detonator sensitive
- Ammonium nitrate and mineral oil or diesel oil (English fuel oil), which is used in mining as handling-safe explosive.
- Initial explosives are found in commercial detonators. Initial explosives are characterized by high sensitivity to friction, shock, impact and heating. Bang Mercury is z. B. already by heating to 160 ° C (fuse) or by a 4 cm height detonated falling 2 kg monkey. The initial detonation with detonators was invented in 1862 by Alfred Nobel. Important initial explosives are
- Lead styphnate (leadrinitroresorcinate), tetracene,
- Nickel hydrazine nitrate (NHN), hexamethylene triperoxide diamine (HMTD), acetone peroxide (DADP, TATP or APEX), 3-nitrobenzene diazonium perchlorate, mercury azides,
- Tetraamine copper (I) chlorate TACC
- copper acetylide TACC
- Initiation charges also referred to as an initial enhancement detonator or IV detonator
- IV detonator is commonly used with compressed, cylindrical tetryl, trotyl, phlegmatized (reduced sensitivity) hexogen, nitropenta, picric acid, and other explosives. All these substances have in common that they have a greater sensitivity to the initial impulse than the explosive of the main charge (eg ANFO, cast TNT, powdery explosives).
- Rock blasting is often used in addition to blasting cartridges of gelatinized explosive to initiate the main charge from powder explosives or emulsion explosives.
- the mass and shape of the IV detonator are calculated so that the detonation produces a pulse that causes the main charge to detonate and to ignite
- Initiation of the IV detonator is by a detonator, an electro detonator or a NE detonator
- Non-electric detonator (Non-electric detonator) triggered.
- IV detonators A problem with the previously used IV detonators is that they either consist of military explosives that are no longer available in the long term (TNT pressed,
- Composition B cast, etc. or classic impact cartridges made of gelatinous explosives (dynamite successor on
- US 3 902 933 A discloses an initial burst charge for the detonation of nitromethane.
- the initial explosive charge is formed by a polyurethane foam which contains dispersed microspheres.
- microspheres may be hollow glass microspheres, resin beads, ceramic beads, etc.
- the inner channel has a small wall thickness to improve the detonation.
- US 3 797 392 A discloses microspheres which are used to sensitize liquid explosives. These microspheres, such as glass bubbles, ceramic microspheres or silicon carbide are immediately dispersed in the liquid explosive and then ignited. In addition, the use of open-pored
- Polyurethane foams described. is therefore to provide an IV
- Detonator specify which is safe applicable, inexpensive and is safe to produce and also safe to handle health.
- Initiation charge which comprises a mixture comprising a nitroalkane and a void-forming agent and a receptacle for an ignition device.
- nitroalkanes are suitable for use in detonator sensitive
- Nitroalkanes may be chemically, e.g. by amine addition and / or mechanically by the creation of small cavities or gas-filled cavities (foaming), i.e. they become susceptible to explosive capsules and behave like explosive explosives. To get the cavitation in
- nitromethane blends produced with commercially available glass micro balloons (GMB) which are more than 6000 m / s detonated and capsule-sensitive (Presles et al., Shock Waves, April 1995, Volume 4, Issue 6 , Pp. 325-329).
- Detonator-sensitive initiation charge formed from a liquid-impermeable material. This avoids leakage of the nitroalkane.
- the detonator-sensitive initiation charge has a concave curvature which is arranged on the opposite side of the receptacle for the ignition device. Under a concave curvature is in the sense of the present
- the concave curvature has a metallic coating.
- the metallic coating can be made of aluminum and can be arranged on the surface of the concave curvature by means of spraying, steaming or as a metallic foil.
- the metallic coating of the concave curvature causes a reinforcing initial pulse in a predetermined direction.
- the concave curvature with metallic coating is of particular importance for achieving a high chemical reaction rate at which the conversion process comes very close to the theoretical value. This will be the
- the ignition device is a detonator, detonating cord or a non-electric detonator.
- the detonator-sensitive initiation charge has a suitable wall thickness. This ensures a secure ignition transfer from the capsule or string to the nitroalkane mixture.
- the wall thickness is dependent on the material of the wall and the mixture used.
- the nitroalkane is selected from a group of 1 to 3
- the nitroalkane is nitromethane.
- the cavity-forming means is designed as a microglass hollow sphere (GMB).
- the cavity-forming agent is designed as a hollow glass microballoon (GMB) with a particle size of 20-200 ⁇ m, preferably 40-150 ⁇ m, particularly preferably 80-120 ⁇ m.
- GMB hollow glass microballoon
- the cavity-forming means is designed as a hollow glass microballoon (GMB) with a grain size of substantially 100 ⁇ m.
- GMB hollow glass microballoon
- the mixture comprises Aerosil.
- Aerosil is meant here a fumed silica.
- the Mixture 1.5-10% by weight, preferably 3-8% by weight, particularly preferably 5-7% by weight of Aerosil, 0.2-10% by weight, preferably 0.5-5% by weight %, more preferably 0.8-2% by weight
- Microglass hollow sphere as well as 85-98,3 Gew. ⁇ 6, preferably 89-95, particularly preferably 91-93 wt .-% nitromethane.
- the mixture comprises 6.5% by weight of Aerosil, 1% by weight of hollow glass microbeads (GMB) having a particle size of essentially 100 ⁇ m and 92.5% by weight of nitromethane.
- the mixture further comprises at least one oxygen-containing compound selected from the group of nitrates for increasing the oxygen balance.
- the oxygen-containing compound is ammonium nitrate.
- Initiation charges are used to initiate non-capsule-sensitive commercial explosives, preferably in downhole and underground wells, to initiate larger booster charges and to use them directly
- Nitroaromatics which are suspected of being carcinogenic and no nitro-esters, which are physiologically problematic by possible vasodilation, formed. This avoids health problems for the users.
- the invention is preferred
- Niroalkane nitromethane is a cheap, due to
- nitromethane is not a classic explosive, which makes transport and storage convenient, and it has Storage Class 3 (Flammable Liquids).
- nitromethane has a low toxicity: LD50 oral rat: 940 mg / kg, WGK 2.
- the detonator-sensitive initiation charges according to the invention are in the
- the components contained in the mixture are not explosives, which requires only low storage and transport costs.
- Embodiments are intended to describe the invention without limiting it.
- pure ammonium nitrate and ANFO (each with 13 g of the
- composition according to the invention in a cylindrical initial charge) with the following composition for the detonative reaction: 6.5%, Aerosil, 1% GMBs about 100 ym, 92.5% nitromethane.
- Detonation velocity of about 4500 m / s were measured, which is a sufficient suitability of the mixture for the initiation of non-capsule-sensitive commercial
