Definitions

the invention relates to high-viscosity emulsion explosive and a method for its production and a method for Spend this highly viscous emulsion explosive in Cavities, in particular boreholes.
the Invention a method for loading boreholes with the high-viscosity emulsion explosive according to the invention over days and underground as well as for loose use in one Density range from 0.5 to 1.3 kg / l.
Emulsion explosives belong to the explosive-free, water-containing nitrate explosives. It is based on a water-in-oil emulsion, which is produced by emulsifying a highly concentrated nitrate salt solution with mineral oil. The salt solution is broken down into very finely distributed droplets - of the order of magnitude of about 10 -6 m diameter - and surrounded by an even thinner oil film of about 10 -8 m thickness. This fine emulsion matrix is the essential prerequisite for the special properties of emulsion explosives. Despite the extremely intimate contact sensitization by in the emulsion matrix finely distributed gas bubbles as reaction centers for the introduction and forwarding of a detonative reaction is required. Emulsion explosives are sensitized either by the introduction of hollow microspheres or by chemically formed gas bubbles (chemical gassing) by a so-called gasing agent.
the emulsion explosive is only after the sensitization, d. H. the formation of the gas cavity body within the Emulsionsmatrix sensitized and thus detonationsdoc. He finds application especially in the overground at the Rock extraction in quarries.
the Emulsion explosive either locally or mixed Matrix stationary premixed and on site only by Gas bubbles sensitized and by charging hose in prefilled holes are filled.
the gasing agent is added and As a result, the formation of gas bubbles within the Emulsion matrix, d. H. the sensitization of the Explosives, when pumping or in the borehole instead.
the Mixed charging device used for this purpose the individual can not Sensitized components safely to the blast site transport, because at this moment no detonatable mixture is present.
Emulsion explosives are liquid pulpy consistency and chemical sensitization at Small diameters of 40 mm and less often not are sufficiently detonatiostipp or capsule sensitive.
Emulsion explosives there is the conventional Emulsion explosives underground more often the problem of critical diameter. This is even with patronized Emulsion explosives due to a dense density of approx. 1.1 +/- 0.1 kg / l at about 25 mm.
the critical diameter is usually 40 mm and more. Underground but blast holes are usually lower Diameter inserted.
Pumpable emulsion explosives conventional type after the Sensitization is not always sensitive to capsules, so that Booster can be used.
Object of the present invention was therefore, the Overcome disadvantages of the prior art and in particular an emulsion explosive of high viscosity to provide, which also meets the requirements for the Use underground for critical diameter, Ignition or capsule sensitivity and consistency met.
Another object of the invention was to provide a method for Spend this explosive in boreholes, in particular obliquely upwardly extending boreholes, ready to provide.
Another object of the present invention was to provide a device with this Emulsion explosive according to the invention prepared and / or in Boreholes can be spent.
the object of the present invention is achieved by a Process for the handling-safe production of highly viscous emulsion explosive (1) by means of Gassing method, comprising the steps of: producing a High Viscosity Emulsion Matrix (10) Conveying the High viscosity emulsion matrix (10) through a conveyor system (30) using a Lubr ceremoniessmediums (15), wherein the lubrication medium (15) has a gas agent (16) having; Mixing the high viscosity emulsion matrix (10) with the lubrication medium (15) at the end of the Conveyor system (30) or loading tube; Post-emulsifying the discharged mixture of high viscosity emulsion matrix (10) and Lubrberichtsmedium (15) for high-viscosity Emulsion explosive (1).
Emulsion explosives are inventively from a Emulsion matrix of high viscosity, and mixing with made by a gassing agent.
a gassing agent By mixing the Emulsion Matrix with the Gassing Agent will be the required gas bubbles in the emulsion matrix introduced, with which this is then sensitized.
the high viscosity emulsion matrix of the invention is preferably from an emulsifier, an oil phase and a Oxidizer phase produced.
the emulsifier is preferred chosen so that the finished emulsion matrix at low Shear initially low tendency to Having post-emulsification and higher shear stress nachemulgiert.
the emulsion matrix of high viscosity is preferred all oxygen-releasing salts in the rest Solution.
the lies in the Compositions used amount of water between 1 and 30 Weight.
the amount used is between 10 and 25 weight percent, more preferred between 10 and 15 weight percent based on the Emulsion phase.
the immiscible with water continuously organic phase (oil phase) of the water-in-oil emulsion contains between 2 and 15 weight percent, preferably between 4 and 8 Weight percent based on the emulsion phase.
the emulsifier component of the composition of Emulsion matrix of high viscosity preferably contains between 0.5 and 5 weight percent of the emulsion phase.
the Emulsifier component preferably consists of an emulsifier from PIBSA type and from a sorbitan ester in any one Mixing ratio. It can also be a pure PIBSA emulsifier be used.
the mass fraction of the emulsifier is preferably chosen so that on the one hand the highest possible Stability reserve is achieved and on the other hand the Subsequent emulsification, with a viscosity increase of the Emulsion is accompanied, can be influenced purposefully.
As an emulsifier a mixture (blend) consisting of pure emulsifier (active phase) and oil are used.
Particularly preferred is higher in the emulsion matrix Viscosity when using an emulsifier of two Emulsifier components already a first, in the High viscosity emulsion matrix already activated phase of the Emulsifier before and another surplus at not yet activated emulsifiers, the first in the step of After-emulsifying the discharged mixture of High viscosity emulsion matrix and lubrication medium for high-viscosity emulsion explosive post-emulsified.
the Oxidizerphase is preferably chosen so that the Oxygen balance of the high-viscosity emulsion explosive at 0 to + 2.5%, preferably + 0.5 to 1.5%.
the through the inorganic phase caused excess oxygen of the Product allows the addition of other high-energy Components, such as metal powder, preferably Al, Mg, graphite, Carbon black, coal, etc. or a mixture of these components, in Concentrations of preferably up to 2%. This allows the energy content and other thermodynamic data of the high viscosity emulsion explosive for different Applications can be optimized.
an emulsion explosive or a Provided method for its production due to the high-viscosity property now against gravity too can be loaded into a wellbore that is oblique or even vertical was drilled to the top. Due to the high viscosity of the in the manner described explosive flows this no longer from the borehole but remains there against gravity.
Invention becomes higher in conveying the emulsion matrix Viscosity (10) between this and the lubrication medium (15) no turbulent, but a largely laminar Maintained flow, in particular a laminar Flow with a Reynolds number of less than 2300, preferably less than 2000, more preferably from less than 1500.
a laminar flow in this sense means that in particular no shear forces between the Lubrtechnischsmedium and the emulsion matrix occur and so no mixes. There are thus no Turbulence or mixing on. That's the way it is possible the gassing agent until mixing the To transport emulsion matrix at the end of the conveyor system, without any mixing or reaction the gassing agent can take place with the emulsion matrix.
the emulsion matrix (10) has a viscosity of more than 60,000 mPas, preferably more than 80,000 mPas, more preferably more than 100,000 mPas.
the viscosity of a conventional emulsion matrix is up to 50,000 mPas (measured by the method Brookfield, Spindle 7, 10 rpm, 20 ° C).
the inventive Emulsion matrix now has a much higher viscosity. This has been avoided in the prior art so far because it causes a mixture with the gasing agent could no longer be displayed effectively. Surprised was inventively found that even in a Emulsion matrix with a much higher viscosity, especially preferably of over 100,000 mPas mixing with the Gassing agents very well to the required mixing and Re-emulsification or sensitization of the final product can. For this reason, contrary to the prejudices of the State of the art according to the invention an emulsion matrix higher Viscosity selected.
the emulsifier consists of at least two Emulsifier components that are different Emulsify shear stress.
the one in the emulsion matrix high viscosity emulsifier is for the production this matrix has already been activated, d. H. for the production partially emulsified in the matrix. This will be the Emulsion matrix imparted this viscosity first.
the finally received Explosive then has a viscosity above 200,000 mPas, preferably 250,000 to 350,000 mPas and higher.
the High viscosity emulsion matrix has a viscosity of more than 60,000 mPas, preferably more than 80,000 mPas, more preferably more than 100,000 mPas.
an emulsifier of at least two components is thus making it possible to keep the emulsion matrix in a high level Produce viscosity range, and then at Mixing again to the final emulsion explosive to increase decisively in their viscosity.
the lubrication medium (15) comprises a mixture of water and gas agent (16).
the Lubrification properties of the lubrication medium be improved.
Invention is a high viscosity emulsion explosive obtained having a density of at least 0.5 kg / l to 1.2 kg / l, preferably 0.9 kg / l.
the production method described makes it possible to the density of the resulting emulsion explosive through the To set choice of different parameters.
the composition of the emulsion matrix can in particular be the type and manner of mixing in the end to a change in the Contribute density. By a particularly intensive mixing This makes it possible to generate low densities.

static mixer especially preferably by a number of preferably different static mixers are the emulsion matrix and the Lubricating medium mixed together, making it to the optimal gas formation as well as preferred for Post-emulsification of the explosive comes. So far was in the state The technique has been assumed to be use a static mixer would not be enough to one appropriate adequate mixing between the gasing Make agents and the emulsion matrix. It is particularly preferred, several static mixers depending on Use in a row.
the free cross sections or the length of the integrated Mixing distance can be varied to flow rate, To influence the mixing quality and final viscosity of the emulsion.
the geometry of the mouthpiece is varied, around a directional beam, a side beam, etc. adjust and always an optimal filling of the holes to ensure.
the mouthpieces are designed so that by means of a quick change system an exchange within the shortest possible time is possible.
the object of the invention is also achieved by a Method for bringing a high-viscosity Emulsion explosive (1) in a cavity (5), in particular a borehole, comprising the steps Promote an unsensitized emulsion matrix higher Viscosity (10) through a conduit system (33), injecting a Lubr ceremoniessmediums (15) in the conduit system, wherein the lubrication medium (15) has a gas agent (16) contains and between the emulsion matrix and the inner wall of the piping forms a lubricating film, Mixing the emulsion matrix (10) with the gasing agent (16) at the transition from the pipe system into the to be filled Cavity (5).
the task is also solved by a Emulsion explosive which after a Process is made.
the emulsion explosive thus obtained is distinguished in particular by having a viscosity of more than 200,000 mPas, preferably more than 250,000 mPas, especially preferably has more than 300,000 mPas and thus one has extremely high viscosity.
This high viscosity allows it the explosive, in the cavities once pumped there also to stick and not like the conventional one pumped explosives against gravity again to drain. Since the achieved high viscosity according to the invention preferably also with a correspondingly low density can be combined is the explosive thus obtained ideally suited for use underground or in tunnel construction get.
