Description

Description of the invention

The invention relates to industrial explosive mixtures (IS), in particular to the simplest explosives of increased 2 density for the mining industry and other industries.

The closest technical solution, chosen as a prototype, is an explosive mixture containing granular ammonium nitrate, liquid fuel, aluminum-bearing material and small coke-chemical production waste, where the liquid fuel contains diesel fuel or liquid lubricant waste, or combustible oil refining waste as an aluminum-bearing component contains aluminum powder (powder) or ferrosilicon (powder), 70 av as small waste of coke chemical production contains small blast furnace coke waste of a fraction of no more than 1.5 mm with the following ratio of components in percent by mass fraction: ammonium nitrate 83-1 liquid fuel (diesel fuel or liquid lubricant waste, or combustible oil refining waste) 6.5-0.5 12 aluminum-containing component (aluminum powder (powder) or ferrosilicon (powder) 1.5--0.5 small waste of coke chemical production (small waste of blast furnace coke fraction no more than 1.5 mm) 90.5

This mixture has the following explosive properties: density 1130Kg/cm C oxygen balance 002296 calculated heat of explosion A18OKJ/kg volume of explosion gases 980l/kg critical diameter of the open charge 50-bbmm s 29 critical diameter of the charge in a strong shell 30-Z5mmM Ge) ( Ukraine, Patent Mo46594, IPC 7 СО6В31/00, 2004).

The disadvantages of the known explosive mixture are insufficiently high explosive characteristics, physical stability and energy consumption, both during its preparation and during storage, transportation to the place of explosive works, charging of wells and holes, significant costs for the manufacture of the explosive mixture, in addition, it is narrowed " - the field of application with insufficiently high economic efficiency of blasting works. The presence of a fine fraction of no more than 1.5 mm of blast furnace coke waste in the composition of the fuel significantly reduces its energy performance according to Me. due to the fact that the presence of small particles of small blast furnace coke waste in the HC fraction up to 1.5 mm (not He) ensures a uniform distribution of components over the mass of the HC, which worsens the energy indicators of the explosion. In addition, for the combustion of these small particles saturated with diesel fuel, a lot of energy is spent, and at the front - the detonation wave, the temperature decreases, which leads to a decrease in the detonation speed. Due to the high speed of propagation of the detonation wave, some blast furnace coke particles of this fraction do not have time to burn completely, which worsens the temperature regime of the explosive chemical reaction. The high content of liquid fuel, aluminum powder (powder) in the mixture increases the cost of manufacturing the explosive mixture, which negatively affects the economic efficiency of explosive works. A small amount of the fine fraction in the volume of small waste (no) blast furnace coke of a fraction of no more than 1.5 mm in the explosive mixture during its preparation leads to insufficient dense covering of the surface of ammonium nitrate granules with fuel-wetted coke particles and strong retention on its surface, which leads to delamination of the air under the influence of the reverse jet of air during charging into the well, disrupts the homogeneity of the prepared mixture along the length of the well charge, which, accordingly, worsens the energy indicators of the explosion. it. The use in the explosive mixture of small waste only from coke chemical production - small waste

Ge") of blast furnace coke with a fraction of no more than 1.5 mm with a large content of liquid fuel and aluminum powder (powder) not only narrows the scope of its application, but also increases the cost of production, which reduces the economic efficiency of blasting operations with insufficiently high energy indicators. - about 70 The following are the reasons preventing the obtaining of the technical result of the invention claimed by the prototype:

What. - the presence of small particles of blast furnace coke in the HC fraction of no more than 1.5 mm does not ensure uniform distribution of components in the HC mass, which significantly worsens the energy indicators of the explosion; - the high content of liquid fuel and aluminum powder (powder) in the aircraft increases the cost of manufacturing 22 aircraft, narrows the scope of its application and lowers energy performance;

F! - a small amount of the fine fraction in the volume of fine blast furnace coke waste of a fraction of no more than 1.5 mm leads to an insufficiently dense enveloping of coke particles moistened with liquid fuel and their firm retention on the surface of ammonium nitrate granules, which negatively affects explosive characteristics, physical stability and energy intensity of the aircraft; 6o - the use of small blast furnace coke waste of a fraction of no more than 1.5 mm as small waste of coke-chemical production in the nuclear power plant increases the cost of manufacturing the nuclear power plant, narrows the scope of its application and reduces energy performance.

The object of the claimed invention is the development of the explosive mixture "Igdanit MK-1", in which by providing the possibility of obtaining a cheap TNT-free metal coke explosive mixture with high energy performance indicators due to the replacement of small blast furnace coke waste of a fraction of no more than 1.5 mm with a small amount of -D -

small foundry coke waste with a wide fraction up to 0.7 mm, containing a small amount of aluminum (powder) or secondary aluminum (powder), or silicoaluminum (powder), or silicon powder, a small amount of liquid fuel as diesel fuel or waste liquid used lubricants with a density of no more than 1g/cm3 of the increased amount of ammonium nitrate with the additional content of iron-containing sludge of a wide fraction up to 0.7 mm or iron concentrate of a wide fraction up to 0.7 mm, or agglomerate of a wide fraction up to 0.7 mm, or ferrosilicon of the same fraction, improvement of explosive characteristics is achieved, increasing physical stability and energy intensity, both during the preparation of the explosive mixture and during its storage and transportation to the place of blasting, charging wells and holes mechanically and manually and equipping 70 cumulative charges with a reduction in the cost of its production while preserving the ecological condition in the area blasting works with complete utilization of p industrial waste, both coke-chemical production and powder metallurgy, and due to this, the scope of application of the explosive mixture with high economic efficiency of explosive works is expanding.

The task is solved by the fact that the explosive mixture "Igdanit MK-1", which contains granular ammonium 75 nitrate, liquid fuel, an aluminum-containing component (powder) and small waste of coke chemical production, according to the invention, it additionally contains iron-containing sludge of a wide fraction up to 0./7mm or iron concentrate with a wide fraction up to 0.7 mm, or agglomerate with a wide fraction up to 0.7 mm, or ferrosilicon of the same fraction as liquid fuel containing a small amount of diesel fuel or waste liquid used lubricants with a density of no more than 1 g/cm7, as an aluminum-containing component ( powder) contains a small amount of aluminum (powder) or secondary aluminum (powder), or silicoaluminum (powder), or silicon (powder), and as small waste of coke chemical production contains a small amount of small waste of foundry coke with a wide fraction of up to 0.7 mm in the following ratios of components in percent by mass fraction: liquid fuel (diesel fuel or waste used oils dense with a weight of not more than g/cm C) 2.023 se aluminum component (powder) (aluminum (powder) or secondary aluminum (powder) or silicoaluminum (powder)), or 0.01. o silicon (powder) 1.0 small waste of coke chemical production (small waste of foundry coke with a wide fraction up to 0.7 mm 7.0 iron-bearing sludge with a wide fraction up to 0.7 mm or iron concentrate with a wide fraction up to 0.7 mm or agglomerate with a wide fraction 30 0.7 mm, or ferrosilicon of a wide fraction up to 0.7 mm, the rest is ammonium nitrate.

Essential features of the claimed invention are: - granular ammonium nitrate; F - liquid fuel; (se) - aluminum component (powder); - small waste of coke chemical production; - - iron-containing sludge with a wide fraction up to 0.7 mm or iron concentrate with a wide fraction up to 0.7 mm, or agglomerate with a wide fraction up to 0.7 mm, or ferrosilicon of the same fraction; - liquid fuel contains a small amount of diesel fuel or waste liquid used lubricants « 20 with a density of no more than 1 g/cm3; в-в - the aluminum-containing component (powder) contains a small amount of aluminum (powder) or secondary aluminum (powder), or silicoaluminum (powder), or silicon (powder); :z" - small wastes of coke chemical production contain a small amount of small wastes of foundry coke with a wide fraction up to 0.7 mm with the appropriate ratio of components in percent by mass fraction.

The new essential features of the claimed invention are: - iron-containing sludge with a wide fraction up to 0.7 mm or iron concentrate with a wide fraction up to 0.7 mm, or agglomerate with a wide fraction up to 0.7 mm, or ferrosilicon of the same fraction; (o) - liquid fuel contains a small amount of diesel fuel or waste liquid used lubricants

Ge) with a density of no more than 1 g/cm3; - the aluminum component (powder) contains a small amount of aluminum (powder) or secondary aluminum (powder), or silicon aluminum (powder), or silicon (powder); "M - small waste of coke chemical production contains a small amount of small waste of foundry coke with a wide fraction of up to 0.7 mm with the appropriate ratio of components in percent by mass fraction.

Thanks to the new essential features, a cheap TNT-free metal coke explosive mixture "Igdanit dvo MK-T" is formed with high energy indicators, improved explosive characteristics, increased physical stability and energy intensity, both during the preparation of the explosive mixture and during its storage and

F) transportation to the place of blasting, charging of wells and holes by mechanical means and by hand and equipment of cumulative charges while preserving the ecological condition in the area of blasting with full utilization of industrial waste, both coke-chemical production and powder metallurgy, because the reduction of the production cost explosive mixture, and due to this, the scope of application of the explosive mixture with high economic efficiency of blasting works is expanding.

The analysis confirms that small foundry coke waste with a wide fraction of up to 0.7 mm and iron-containing sludge of the same fraction when mixed with liquid fuel as diesel fuel or waste liquid used lubricants with a density of no more than 1 g/cm3, due to the high porosity of foundry coke particles, provide instant 65 Absorption and strong retention of particles by the pores under the influence of capillary pressure up to 20905 of liquid fuel from its volume, since the particles of iron-containing sludge have a less expanded pore network, but such a structure that under capillary pressure, the pores instantly absorb and firmly hold up to 1595 of liquid fuel from its volume, both during preparation, storage, transportation and loading into wells and holes, and when used for equipping cumulative charges.

When the density of liquid fuel as a waste of liquid used lubricants is more than g/cm3, under the influence of capillary pressure in the pores of foundry coke and iron-containing sludge particles, due to the increased density of liquid fuel, the pores of the particles do not absorb it and its volume is placed between the particles. Under the influence of molecular forces, tension films of such liquid fuel are created on the surface of the component particles and between them, when they are mixed with this liquid fuel, it leads to the fact that small particles of foundry coke, iron-containing sludge 70, aluminum powder are attracted to each other, forming lumps of high density, which significantly worsens the energy indicators of the explosive mixture.

In the production of the explosive mixture "Igdanit MK-1" (metal coke) uniform mixing of the components is ensured in a short period of time, due to the presence of components with a wide fraction up to 0.7 mm, with full and uniform penetration of liquid fuel under the influence of both osmotic and capillary pore pressure particles, 75 V in the pores of the particles of the components - ammonium nitrate, small wastes of foundry coke and sludge of iron-containing or iron concentrate, or agglomerate, or ferrosilicon with the formation of a film of tension on their surface at the molecular level, with mutual penetration of the particles of fuel-moistened particles of the components of the explosive mixture, dense sticking of the remaining part of the small moistened particles of the components on the moistened fuel granules (particles of granules) of ammonium nitrate with their firm retention on the surface of the granules and with the filling of the intergranular space with the remainder of the liquid fuel moistened fuel particles. Thanks to this, the perception of the explosive device to the initial impulse increases, which contributes to the improvement of explosive characteristics, the increase of physical stability and energy intensity, and this makes it possible to destroy rocks of various strengths with borehole charges, the hole method, and to use them for equipping cumulative charges, as well as to expand the scope of application with high the effectiveness of blasting operations while preserving the ecological state in the area of blasting operations with full disposal of industrial waste, both coke-chemical production and powder metallurgy. i9)

The rational ratio of the components of the declared explosive mixture is as follows in percentage by mass-I part: me) liquid fuel (diesel fuel or waste liquid used lubricants with a density of no more than 1 g/cm 3) 2.0-2.3 («e) aluminum component (powder) (aluminum (powder) or secondary aluminum (powder) or silicoaluminum (powder)), or 0.01 silicon (powder) 1.0 - small waste of coke chemical production (small waste of foundry coke of a wide fraction up to O, 7 mm) 7.0 "And iron-bearing sludge of a wide fraction up to 0.7 mm or iron concentrate of a wide fraction up to 0.7 mm, or agglomerate of a wide fraction 30 up to 0.7 mm, or ferrosilicon of a wide fraction up to 0.7 mm ammonium nitrate the rest. 25 Method of preparation and action of the claimed explosive mixture.

GF) 8895 of granular or crushed ammonium nitrate (AS) from the total mass of the explosive mixture (AS) is loaded into the hopper of the mixing machine, which is authorized by the State Inspection and Protection of Ukraine for the production of explosive cue mixtures, for example "Tera-500", and liquid fuel containing a small amount is poured - 295 of the total volume of fuel oil, diesel fuel or waste liquid used lubricants with a density of no more than 1 g/cm" are mixed for 5-7 minutes. In the process of mixing, due to osmotic pressure, a portion of the liquid is absorbed into the pores of the upper dense layer of the AS granules fuel, some part of it envelops the AS granules, creating a tension film on their surface, and the rest of the liquid fuel migrates through the intergranular space through the thickness of the AS volume to the bottom of the hopper of the mixing machine. After mixing, 395 of iron-containing broad fraction sludge is added to the hopper to 0, 7 mm or iron concentrate of a wide fraction up to 0.7 mm, or agglomerate of a wide fraction up to 0.7 mm, or ferrosilicon of the same fraction, then a small amount - 795 small waste foundry coke with a wide fraction up to 0.7 mm and a small amount - 0.0195 of the total volume of the aluminum-containing component (powder) containing aluminum (powder) or secondary aluminum (powder) or silicoaluminum (powder ), or silicon (powder) and the mixing process is continued for 7-10 minutes until a homogeneous mass is formed.

In the process of mixing, due to the capillary pressure of the pores of the particles into the pores of the larger particles of small waste foundry coke and sludge of iron-containing or iron concentrate, or agglomerate, or ferrosilicon, a part of the remaining liquid fuel is absorbed, with which, at the same time, fuel-moistened dust particles of the aluminum-containing component - aluminum or secondary aluminum, or silicoaluminum, or silicon, and there is mutual penetration into the pores of larger particles of foundry coke waste, moistened with fuel, of small particles (dust) of iron-containing sludge or iron concentrate, or agglomerate, or ferrosilicon, and into the pores of larger particles of iron-containing sludge or its substitute penetration component of fuel-wetted fine particles (dust) of foundry coke waste. The remaining liquid fuel that has not been absorbed envelops the remaining small particles of powder, dust of the mixture components, creating tension films on their surface at the molecular level and due to the large difference in weight and volume between the particles of 7/5 Energy-carrying components and AS granules, small particles (dust) moistened with liquid fuel are attracted to the surface of wetted and maximally saturated AS granules, tightly enveloping the surface of AS granules and firmly held on their surface, thanks to the molecular forces of cohesion of homogeneous liquids under the influence of molecular tension forces and capillary and osmotic pressure of AS pores, and some residue of these particles partially fills the intergranular space, forming a dense structure of the explosive mixture.

The produced explosive mixture "Igdanite MK-1" has a homogeneous, dark gray mass with a density of 1140-1200Kg/m?3, it is loaded into the pneumatic charging machine URZ-1 for charging holes or into the pneumatic transport machine MTZ3-3 for charging wells in underground conditions for mining, or in the M3-8 transport-charger for transporting the explosive mixture to the place of blasting for charging wells on quarry blocks. The explosive mixture can be used to equip cumulative charges. at

Conducted experiments when charging into a well with a diameter of 250 mm showed that due to osmotic and capillary pressure in the pores of the components of the explosive mixture, liquid fuel, for example, diesel fuel, does not migrate along the charge column. The duration of the charge in the well, depending on the number of drilled wells, ranges from 3 to 7 days. what

The small content of liquid fuel in the mixture, which is 2.0-2.395 relative to the mass of the explosive mixture, thanks to the small particles of the components of a wide fraction up to 0.07 mm, confirms not only the uniform mixing of the components, the complete and uniform saturation of their particles with liquid fuel with their coating, as well as strong and He) dense retention of them on the surface of granules (particles) of ammonium nitrate with dense filling of some of them from the intergranular space, which creates a dense structure of metal coke explosive mixture with full use of the given volume of liquid fuel, which improves its explosive characteristics with increasing - physical stability and energy intensity with a decrease in the production cost and expands the scope of application with high economic efficiency of blasting works.

To study the shelf life of the resulting explosive mixture, 21 kg of explosives were produced, which "were packaged in 7 kg polyethylene bags and stored in the explosive materials warehouse for 90 days."

Migration of VS was not observed. - c In order to determine the sensitivity to the initial impulse of the missile after storage for 90 days, three cardboard tubes with a diameter of 160 mm were filled with missiles of 7 kg each and detonated. In each tube, the anti-aircraft gun was initiated by one cartridge - a combatant, "ammonite 6 ZhV (2532 weighing 250 g). The detonation of the anti-aircraft gun in all three tubes was complete. The sensitivity to the initial impulse did not decrease after storage.

Example 1 - At the quarry of OJSC "CGZK" when undermining rocks with a strength of 18-20 points on the scale of prof. Protodyakonov charged wells with a diameter of 250 mm with explosive mixture "Igdanit MK-1" in the amount of 5 tons. The mixture was produced cyclically on the Tera-500 mixing machine, 500 kg from the total volume. For this purpose, 43-5 kg of granular ammonium nitrate was loaded into the hopper of the mixing machine, 10 kg of diesel fuel was poured in and mixed for 20 5 minutes. The pores of the upper dense layer of ammonium nitrate absorbed almost 3095 of diesel fuel from its volume, almost 1095 of diesel fuel, created a tension film at the molecular level on the surface of the ammonium nitrate granules. And the rest of it, almost 6095 along the intergranular space, migrated to the bottom of the bunker. After of this, 15 kg of the total volume of the mixture of iron-containing sludge with a wide fraction up to 0.7 mm, 35 kg of fine foundry coke waste of the same fraction and 5 kg of an aluminum-containing component (powder) containing aluminum (powder) were added to the hopper. It was mixed for 7 minutes until a homogeneous mass was formed. During displacement, due to the capillary pressure in the pores of the particles of fine foundry coke waste and iron-bearing sludge of a wide fraction up to 0.7 mm, mutual absorption of the part of the diesel fuel-moistened particles and dust of these components takes place, with the remaining particles and dust covered with diesel fuel. At the same time, in the pores of these of the components, fuel-soaked aluminum dust particles are sucked in. The added amount of di of kerosene is fully used. 60 The resulting mixture has a homogeneous structure of a loose mass of dark gray color with a density of 1200 kg/m?. Each portion of Б5О0Окг from the total weight of the explosive mixture, which is bt, was loaded into the M3-8 transport-charging machine and transported to the loading block of the quarry.

Charging of the explosive mixture into wells with a diameter of 250 mm was carried out according to known technology.

The explosive mixture of each well charge was initiated with the help of an intermediate detonator - two T-400 checkers and a DSh-12 detonating cord. When the well charge column is initiated under the action of high pressure and temperature at the front of the detonation wave, ammonium nitrate granules with particles and dust of foundry coke, iron-containing sludge and aluminum powder tightly adhered to their surface are instantly compressed and crushed, while diesel fuel instantly evaporates from their pores. , the vapors of which interact with part of the oxygen released from the crushed ammonium nitrate granules, the pressure and temperature of the chemical reaction increase, particles of foundry coke and aluminum begin to burn, and iron oxides in the iron-containing sludge under the influence of the products of combustion of foundry coke are reduced to metallic iron, which instantly burns in oxygen released from the AS. The temperature and pressure at the front of the detonation wave increases, which increases the speed of detonation and improves explosive characteristics, increases physical stability and energy intensity.

Example 2. 70 In the underground conditions of the mine named after Ordzhonikidze on rocks with a strength of 18-20 points on the scale of Prof.

Protodyakonov, an experiment was conducted on charging and detonating a battle with 32 holes 1.5 m long and 40 mm in diameter. The holes were charged with the explosive mixture "Igdanit MK-1" using the charging machine URZ-1, the initiation of each hole was carried out according to the technical card, with one cartridge - ammonite bullet BZHV F32, weighing 250 g. The charging and detonation of the explosive mixture took place without changing the technology used for 7/5 charging with standard explosive ammonite 79/21. The analysis of the results of the explosion showed that all the charges in the holes detonated completely, the length of the penetration into the rock was 135-140 cm, the utilization factor of the hole is 0.86.

As the experiment showed, when pneumatically charging the claimed mixture into the hole, its density was 1200 kg/m3. Such a saturation of energy per unit volume of the charging hole allows crushing rock of high strength up to 20 points on the scale of prof. Protodiakonova with high grinding efficiency.

The presence of a small amount of aluminum powder with an increased amount of porous iron-containing sludge particles of a wide fraction up to 0.7 mm and an increased amount of small waste foundry coke particles of a wide fraction up to O0.7 mm, which ensure the absorption and retention of a given amount of diesel fuel, which necessary for the start of an explosive reaction give the explosive mixture the ability to possess high energy indicators of the explosion. at

The composition of the declared explosive mixture stably detonates from ammonite 6 ZhV 232 combat cartridge in holes with a diameter of 30-40 mm and wells with a diameter of 100-250 mm, the mixture also detonates from a reinforced assembly of the detonating cord (DSheE-12). Moistening the explosive mixture with water up to 495 does not reduce the explosion indicators, the mixture stably detonates from the ammonite 6 ZhV 023432 250g cartridge, which allows charging of moistened wells. "-

The application of the explosive mixture "Igdanit MK-1", which is claimed, will improve explosive characteristics, increase physical stability and energy intensity, both during the preparation of the explosive mixture, and during its storage (22) and its transportation to the place of blasting, charging wells and holes with mechanical method with and manually and equipping cumulative charges with a reduction in the cost of its manufacture while preserving the ecological condition in the area of blasting with full utilization of industrial waste, both coke-chemical production and powder metallurgy, and due to this, the scope of application of the explosive mixture with high economic efficiency is expanding blasting works, in connection with the replacement in the proposed explosive mixture of small wastes of coke chemical production - blast furnace coke of a fraction of no more than 1.5 mm in a mass fraction of 95 (9--0.5) with a small amount of small wastes of foundry coke of wide fractions up to O0.7 mm in mass. 95 (7.0) with the content of small circles bones in mass. 9o (0.01--1.0) of aluminum-containing component (powder) as aluminum (powder) with or secondary aluminum (powder), or silicoaluminum (powder), or silicon (powder) and in mass 9o (2.0-2.3) of liquid fuel in the form of diesel fuel or waste liquid used lubricants with a density of no more than 1 g/cm3 with an additional additive of a small amount of iron-containing sludge of a wide fraction up to 0.7 mm or iron concentrate of a wide fraction up to O0, 7 mm, or agglomerate of a wide fraction up to 0.7 mm, or ferrosilicon of the same - 15 fraction and with the content of a large amount of 9% by mass of ammonium nitrate with the appropriate ratio of components.
