Definitions
- the present invention relates to the field of the preparation and implementation of explosive products including explosive emulsions used in the extraction of raw material and mining industry.
- a discontinuous aqueous phase consisting of various oxidizing salts in aqueous solution.
- ammonium nitrate sodium nitrate
- calcium nitrate The most frequently used oxidizing raw materials in this industry are: ammonium nitrate, sodium nitrate, calcium nitrate. With regard to fuels, it is gas oil that is either pure or mixed with new or used mineral oils, especially recycled motor oil.
- the present invention relates to the manufacture of explosive charges from an emulsion or matrix that is sensitized by mixing with reagents that react with the emulsion and generate a chemical gasification. More particularly, but in a nonlimiting manner, for reacting with ammonium of said emulsion matrix (hereinafter M), a gasification reagent (hereinafter R) based on sodium nitrite or equivalent is used. in the presence of a catalyst such as an acid, especially acetic acid of the following chemical reaction: NH 4 + + NO 2 - ⁇ N 2 + 2H 2 O
- the present invention relates more particularly to the implementation of these products in a hole in which a priming charge and a detonator wire are placed and in which the explosive products (emulsion mixture + gasification reagent) are transferred using a flexible hose.
- EP338707 describes an installation in which the two emulsion and gasification reagent components are mixed at a sort of rigid lance or gun which is introduced in small quantities into a hole. It is not an installation in which products are remotely stored in larger quantities in a truck and transferred using pipe (s) unwound (s) from a reel to a load hole . This type of installation can only be used to load holes with small diameters (less than 50mm) as it is repeated several times in this document.
- the present invention relates more particularly to a process in which the emulsion and porosity reactants are mixed at the site of use of the explosive and more particularly in a hole, in particular a borehole, which the an explosive charge is supplied by means of a transfer line from an installation where the emulsion matrix is made and / or stored at a distance from the hole.
- the hole has a depth of 5 to 30m and a diameter of 5 to 50 cm.
- the basic raw material, the emulsion matrix can be produced on site by a modular plant as described in PCT / FR2014 / 050032 or by mobile installation called UMFE (Mobile Explosive Manufacturing Unit) therefore trucks carrying materials useful for manufacturing that go to the site of use (mines, quarries or construction site) for the production of explosives.
- UMFE Mobile Explosive Manufacturing Unit
- the reactants and catalyst are introduced together and mixed with the emulsion matrix in a static mixer upstream of the loading line whose downstream end is introduced into the mine hole for pump the explosive product.
- a static mixer upstream of the loading line whose downstream end is introduced into the mine hole for pump the explosive product.
- Gasification begins after the introduction of the gasification reagent and the mixture begins to be explosive from the introduction of the gasification reagent therefore in the transfer pipe which creates pressure increase constraints in the pipe and risks to safety because the pipe is filled with explosive.
- one can not vary the density in real time during filling of the hole because there is a relatively large and reliably indeterminable product contained in the pipe to be taken into account.
- Another problem underlying the present invention relates to the implementation of explosive mixtures of different densities during filling according to the depth of the hole or between different holes.
- it is advantageous to be able to produce a product of higher density, about 1.2 in the bottom of the hole and a lightened density of about 0.8 at the top of the column.
- the downhole is more difficult to destroy and requires more explosive volumetric energy than the upper parts, and an optimal explosion in a borehole than the explosive energy column.
- the rock mass to be destroyed varies in composition and volume between the borehole and the free surface, depending on the depth and also because of the deviations resulting from the inclination of the substantially cylindrical borehole, and from one hole to another because of the different inclinations varying from 0 to 25 ° of the said holes and the heterogeneity of the rock mass composition.
- the justification for making an explosive product lower in density is also to reduce the cost of shooting because if the density decreases, this means that there is less mass of product and therefore a lower cost of explosive product.

- the stop 8 has the essential function of holding the static mixer 7 within the downstream end of the first pipe 6i.
- the unscrewing of the abutment 8 makes it possible to release the first mixer 7 from the downstream end of the first pipe 6i and thus to be able to cut the downstream end of the pipe 6i when it is damaged after a certain number of uses because the outer surface of the downstream end of the hose 6i in contact with the walls of the drill holes 11 formed of rock mass 15 tend to damage the downstream end of the hose 6i during the operation as described below.
- the second pipe 6 2 is removed from the inside of the first pipe 6i by uncoupling at the collar 1c as described above or by disconnecting the pipe 1b and closing said second inlet port 2 has a cap and orienting the valve V3 three channels so that all the gasification reagent passes through the lbi pipe and mixes with the matrix upstream flow of the second mixer 2.
- the explosive product is transferred via the conduit 6i to a borehole in which the downstream end 6if of the hose 6i is disposed.
- the static mixer 7 in practice extends over a length of 0.5 to 1 meter so that the explosive product produced is in reduced quantity inside the first hose 6i.
- the static mixer 7 in practice extends over a length of 0.5 to 1 meter so that the explosive product produced is in reduced quantity inside the first hose 6i.
- a method according to the invention is implemented in which the density of the explosive product produced continuously is varied during the filling of a borehole 11 in a single pass, that is to say, without having to raise the pipe 6 during filling, as described below.
- the emulsion consists of the following components:
- nonionic surfactants 1%,
- ammonium nitrate and / or calcium and / or sodium approximately 75%
- ammonium and / or calcium nitrates are added in a proportion of 15 to 35% and a catalyst for example of acetic acid in a proportion of 0.5 to 2%. to which one can also add aluminum (in the form of powder of particle size between about ⁇ and 2mm) in a content of 1 to 10% by weight also.
- This matrix is thus obtained according to the present description within the first reservoir 1-1.
- An example of a matrix formulation is therefore: mineral oil and / or motor oil: 4.55%, - gas oil: 0.7%
- a gasification reagent which is here in particular an aqueous solution of about 20% of sodium nitrite and 80% of water may include catalysts such as sodium thiocyanate , sodium formate, zinc nitrate and / or calcium nitrate.
- the method of sensitizing the matrix consists of a chemical reaction between said gasification reagent and the ammonium nitrate contained in said matrix.
- This chemical reaction releases a gas, in this case nitrite reacted with nitrate to form nitrogen gas, which generates sensitization of the product by the creation of "hot spots", that is to say interstices in the mixture product allowing the propagation of the shock wave, therefore the detonation of the explosive product.
- the product is therefore explosive because of this sensitization.
- the increase in the quantity of gas bubbles decreases the density of the product and therefore the explosive energy obtained for a constant volume of hole (volume energy).
- the density of the basic emulsion (not supplemented) described above is for example about 1.4 to 1.6 and the density of the supplemented emulsion defining said matrix as described above, before mixing with the gasification reagent is 0.8 to 1.3.
- the density of the gasification reaction mixture product within said first mixer is from 1.25 to 1.45 according to the respective proportions of quantities and / or flow rates of said matrix and said gasification reagent and the density of the explosive product after gasification. is from 0.8 to 1.2.
- the average energy of an explosive product of density 1.2 is 3.7 MJ / kg, ie 4.44 MJ / L.
- the explosive energy will be 1.85 to 5.55 MJ / L.
- the automated control and control unit 9 makes it possible to control the proportional valves VI and V2 regulating the flows of matrix and gasification reagent, and the actuation and speed of the motors of the pumps 2-1 and 2-2.
- the flow rates X and Y are provided by calibrating the pump 2-2 speed sensor 2-2 for the values of X (kg / min) and by the flow meter 2-2a for the gasification reagent Y flow (L / 2). min).
- the operator driving the selected plant will select the desired explosive product densities as well as the corresponding quantities for each density based on his needs analysis in the relevant borehole given the surrounding rock mass environment. the hole to be felled.
- X being constant, the flow rate of gasification reagent is determined automatically from the chart according to the desired density.
- the operator will choose up to four different densities called dl, d2, d3 and d4.
- the densities d1 to d4 of explosive products to be produced and the corresponding quantities are entered at the level of the central unit 9 via a touch pad 9a appearing on the screen of the graphic interface 9b. The operator can then start a pumping cycle.
- the centralized and automated control unit 9 then automatically controls the regulation of the flow and therefore the flow rate of reagent R2 for a given matrix flow M.
- the production cycle of a cylindrical hole 20 m deep and 115 mm in diameter will be performed as follows for a supplemented matrix having a density, in the example below, of about 1.3 :
- the automated central unit 9 thus makes it possible to control and control the gasification reagent flow rate values as described above, simply by adjusting the speed of the hydraulic motor of the second pump 2-2 transferring the gasification reagent, and by maintaining a substantially constant flow rate of 125 kg / min of said matrix.
- Such control and flow regulation of the gasification reagent makes it possible to vary, almost in real time, the product density value obtained at the outlet of the first static mixer 7 and discharged directly into the borehole, because of the automation of the control and regulation of the flow of gasification reagent by the central unit 9.
- the CPU 9 may offer additional advantageous features such as the import and export of data, instructions and results in terms of quantity, throughput and density.
- the method according to the invention is also advantageous in that it gives rise to an improvement in safety, the mixture product becoming explosive only at the end of the hose 6 lf thus avoiding the transport over a long distance of dangerous product at inside the pipe.
- the coaxial introduction system of the gasification reagent to bring it into contact with said matrix promotes a faster and more efficient intimate mixing of the two components, which induces, not only: the possibility of optimally varying in real time the density of the product obtained in mixture with the matrix, but also
- the quantity of product contained within the downstream end of the pipe 6i is limited to the explosive product produced gasified in the second downstream portion of the static mixer, or for a mixer 50 cm long in a pipe 6i 32 mm in internal diameter, an amount less than 0.5 kg of a relatively negligible value compared to the amounts of explosive products of different densities that it is necessary to introduce, one can thus consider that the variation of density is thus obtained almost in real time by modification of the ratios of flow of reagent of gasification and matrix.
- the measurement of the density can be carried out by weighing in the open air in a calibrated pot of known volume.
- the process for producing a variable density explosive product according to the present invention therefore consists in varying the gasification of the explosive product in the blasthole, in a manner that is almost instantaneous in order to obtain a differentiation of the density of explosive product in the column. within the borehole, while performing only one loading pass.
