(57) Abstract: The invention relates to a powder keg of explosive compositions based on disposable smokeless gunpowder, explosives type RDX and HMX. According to the invention, the powder explosive composition contains smokeless pyroxylin or ballistic artillery gunpowder or smokeless solid fuel rocket with a particle size up to 50 mm, or a mixture in any ratio, powdered RDX or HMX, or their mixture, a saturated aqueous or aqueous-glycolic solution of ammonium nitrate, or a mixture of ammonium nitrate solution with a liquid oil and a surfactant is a wetting agent. A method of manufacturing a powder explosive composition comprising a dibasic processing fuel phlegmatizer and mixing it with a phlegmatized by the sensitizer. The invention is aimed at creating a powder explosive composition with enhanced efficiency, safe in the manufacture, transportation and use, capable of forming a continuous column of explosive charge in well watered, reducing the critical diameter of detonation charge and open extended field use. 2 S. and owe disposable smokeless gunpowders, explosive substances like RDX or HMX or mixtures thereof and the method of their manufacture for use as industrial explosives). The problem of disposal of the removed from service smokeless powders and propellants, explosives, highly relevant, but quite complex. Burning them is not economically feasible, as this will irrevocably destroyed material values, and applied ecological damage to the environment. The most appropriate direction of the utilization of smokeless powders and propellants, explosives is their use as industrial explosives for blasting borehole charges on the earth's surface. Smokeless powder are made on the basis of cellulose nitrates with various plasticizers. There are nitroglycerine (ballistic) and pyroxylin smokeless powder (Soviet encyclopedic dictionary. - M.: Soviet encyclopedia, 1983, S. 119). Their purpose smokeless powder are divided into artillery and rocket. Smokeless gunpowder, artillery pyroxylin and ballistic and ballistic missile solid fuel have plenty of diversity is friction), sensitivity to detonation impulse, energy parameters. As of explosives destined for recycling are HMX and RDX long-term storage. The high sensitivity of RDX and HMX to mechanical stress (shock, friction), high electrified not allow you to use them as industrial EXPLOSIVES without input phlegmatization. Known powder explosive compositions based smokeless pyroxylin, artillery ballistic powders, ballistic missile solid fuels, mixtures thereof (patent of Russia№№2130446, 1810321, 2026274, 2026275, 2021239,2099396, 2074160, 2092473, 2046117, 2176632 and others, U.S. patent No. 3235425, 4555276, 5445690). Powder explosive compositions and methods of utilization of gunpowder and fuels concerned brands and sizes utilized gunpowder and fuels having certain characteristic values for the sensitivity to detonation impulse (the critical pressure of the initiation of detonation, the critical diameter of detonation, the transmission distance of detonation). When this powder and fuel or processed by phlegmatizer (liquid petroleum products, water, aqueous solutions of inorganic oxidizer), or were introduced sensitizer in the form of TNT, about the tee on the sensitivity to detonation impulse and mechanical influences. Known powder explosive composition (patent of Russia №2086524), including, wt.%: dibasic fuel 20,0-99,8, the sensitizer 0,02-75,0, phlegmatizer else adopted by the authors for the prototype. Explosive composition prototype as a sensitizer contains monobasic fuel, or RDX, or HMX, or aluminum, or aluminum-magnesium alloy, or metallic oxides and salts, or multicomponent mixture; as phlegmatizer - industrial or instrument oil, or its mixture with ammonium nitrate, or multicomponent mixture. The lack of structure of the prototype is a high critical diameter of detonation public charge (90-130 mm), which does not allow to use it for loading boreholes with a diameter of less than 150 mm Explosive composition prototype containing RDX or HMX, unfit for loading flooded wells due to the formation of traffic jams on the surface of the water in the well (due to the poor wettability of RDX), high explosive due to increased sensitivity to mechanical impact, impact and friction, the electrified and accumulation of charges of static electricity in the manufacturing process, transportation, storage and application. The problem was solved by creating bulk waterproof powder explosive composition containing as dibasic smokeless fuel pyroxylin powder, or ballistic artillery gunpowder, or ballistic missile solid fuel with a particle size up to 50 mm, or a mixture in any ratio, as a sensitizer powdered RDX or HMX, or their mixture, as phlegmatizer - saturated water or water-glycol solution of ammonium nitrate or a mixture of ammonium nitrate solution with the liquid oil in the ratio of 12:1 to 84:1 and a surface-active substance, in the following ratio, wt.%: smokeless pyroxylin or smokeless ballistic artillery gunpowder or smokeless ballistic missile solid fuel with a particle size up to 50 mm, or their mixture is bottom-glycolic solution of ammonium nitrate or a mixture of ammonium nitrate solution with the liquid oil in the ratio of 12:1 - 84:1 10,0-14,0; surfactant is a wetting agent is 0.005 to 1.5. The inventive powder sun as smokeless pyroxylin powder contains granulated, or tubular or lamellar or spherical powder of all grades and sizes, or crushed to a particle size up to 50 mm, or their mixture; as a smokeless ballistic artillery powder comprises a tubular, or spherical, or belt, or plate of all brands and sizes, or cut up to 50 mm, or smokeless ballistic missile solid fuel with a particle size up to 50 mm, or a mixture in any ratio, phlegmatized water or water-glycol solution of ammonium nitrate, or liquid petroleum products. The choice of components and their ratio in the inventive powder explosive composition caused by the following factors. The size of the particles (elements) smokeless powder (fuel) in tens and hundreds times greater than the particle size of powdered RDX or HMX. Powder explosive composition and column borehole charge will be homogeneous component composition and bulk density only in the case when all the voids between the elements of smokeless powder or homeless persons in the om or HMX, or their mixture. The relationship between smokeless powder or smokeless fuel and RDX or HMX, or their mixture were chosen by calculating the volume-density characteristics of this mixture depending on the size of the powder elements with subsequent experimental verification (Menshikov B. A. calculation of density and voidness mixtures of granular materials. Sat. “Blasting”, No. 74/31. - M.: Nedra, 197). It is known that air-dry fine RDX or HMX or a mixture of poorly wetted by water and, despite the high proportion (1.8 g/cm3), a very long time does not sink in water and therefore when charged flooded wells hangs at the mouth of the wells. The use of RDX or HMX or mixtures thereof as component of bulk industrial EXPLOSIVES is only possible after pre-treatment of surface wetting. As wetting agent selected saturated water or water-glycol solution of ammonium nitrate with surface-active substances (SAS). Simultaneously a solution of ammonium nitrate reduces the electrification of RDX or HMX and smokeless gunpowder or smokeless ballistic missile solid fuel, reduces their sensitivity to mechanical impact of the new smokeless gunpowder or smokeless fuels and RDX, or HMX, or mixtures thereof. Declare the number of solution of ammonium nitrate selected from conditions ensure flowability, prevent caking of the powder explosive composition during storage, transportation and loading wells. To prevent freezing during winter operation as phlegmatizer-wetting is used aqueous-glycolic solution of ammonium nitrate with surfactant. When using several brands and sizes smokeless pyroxylin, ballistic artillery gunpowder, smokeless high-energy ballistic missile solid fuel (lamellar, spherical, fine-grained, tape) surface elements can phlegmatizers liquid petroleum product, and then further treated with a solution of ammonium nitrate. As of RDX can be used are stored on databases phlegmatized by ceresin or paraffin RDX after treatment with saturated aqueous or aqueous-glycolic solution of ammonium nitrate containing surfactant. As smokeless powder in the inventive powder sun can be used powder explosive composition consisting of granulated smokeless pyroxylin powder is artillery powders or their mixtures, phlegmatized on the surface of the powder elements of liquid petroleum products (granivory marks FM, BP, BM and others). A known method of manufacturing a powder explosive compounds, including the processing of powders and fuels the phlegmatizer, mixed with a sensitizer, packaging ready CENTURIES, adopted by the authors for the prototype to the proposed method of manufacture. The proposed method is that the pre-produce processing sensitizer - RDX or HMX, or a mixture of 0.85-0,80) parts or all of the amount of water or water-glycol solution of ammonium nitrate with a surface-active agent with stirring until complete wetting superfine powder, smokeless powder or smokeless propellant processed of 0.20 to 0.15 parts of the same solution of ammonium nitrate or liquid oil, or liquid petroleum products and the solution of ammonium nitrate to the uniform distribution of liquid phlegmatizer on the surface of the powder elements; mixing is carried out in a measuring vessel, for example a transport unit packaging by filling first hinge phlegmatized smokeless powder or smokeless propellant, then the sample F. the powder elements with the formation of a homogeneous composition; the open end of the packaging sew or clipshot to prevent moving components of the armed forces in the process of transportation and storage. The proposed method of manufacturing a powder explosive composition can be carried out at the manufacturer's of CENTURIES, and in the field of blasting in the process of loading wells by alternately loading charge wells estimated servings phlegmatized smokeless powder and phlegmatized RDX or HMX, or mixtures thereof. The suggested load order phlegmatized smokeless gunpowder (or phlegmatized smokeless propellant) and powdered RDX or HMX, or mixtures thereof in a single shipping package or charge well allow you to get the aircraft with a uniform distribution of components. Smokeless gunpowder artillery and a number of brands of smokeless ballistic missile solid fuels have a low sensitivity to mechanical stress, a reduced tendency to accumulate charges of static electricity, so they can be used as components of explosive powder formulations without prior surface treatment of phlegmatizer is the Oh! Ah! smokeless ballistic missile solid fuel and the method of their manufacture. As follows from the table, the inventive composition is superior to the prototype level characteristics and provides the main technical result of the invention. Lower critical diameter of detonation of an open battery can be used for loading wells of different diameters. Treatment of RDX or HMX saturated solution of speakers with a surface-active agent (or wetting agent) maintains flowability during the warranty period of storage and peoplemost when charged with water-producing wells without the formation of traffic jams and slowdowns. The selected percentage ratio between the concentrations of RDX or HMX, or mixtures thereof, and smokeless powder allows the use of all types of rocket fuels and smokeless powders - pyroxylin all brands and sizes, ballistic artillery of all brands and sizes, any brand of smokeless ballistic missile solid fuels crushed to particle size up to 50 mm, as well as mixtures thereof in any ratio that allows you to compose powder explosive compounds with a wide range of energy Set to produce an aircraft with a uniform distribution of components and to form a column of the charge constant composition and bulk density.
