Detonation of water gel explosive based on grained single-base powder

Keywords: single-base powder, explosive, detonation, water gel, detonation properties, critical diameter of detonation, detonation overpressure

Article devoted to investigation of detonation ability and some properties of the water gel explosives based on single-base powder. Review of investigation of detonation properties of single-base powder by scientists of Soviet Union and Russian Federation was conducted. Water gel explosives, also known as " slurry" explosives, based on grained single-base powder were investigated. The effect on detonation ability and properties by changing of composition of water gel and its and content in explosive mixture was found and values of critical detonation parameters for that mixtures were provided. Same water gel explosives was investigated by the electromagnetic method of a study of the parameters of shock and detonation waves and comparison of the results of that investigation was carried out. On the basis of the provided investigation were proposed the mechanism of detonation process for water gel explosives based on grained single-base powder.

Industrial explosives and their production technology on the basis of persuasi emulsions

Keywords: ammonium nitrate, Rebinder effect, absorptive reduction of strength, completeness of chemical conversion, multi-component granular explosive, Granulite EF-P

The article emphasizes the importance of industrial explosives perfection and discusses an opportunity of solving the problem of incomplete chemical conversion of explosives due to the application of pore-and-channel forming emulsions providing the absorptive reduction of strength. The influence of Rebinder effect on ammonium nitrate granules is shown. Some results of Granulite EF-P tests are described. Its liquid phase contains water-in-hydrocarbon emulsion providing the formation of additional systems of pores and channels in ammonium nitrate granules without heating in the process of industrial explosives fabrication thus resulting in the multiple expansion of the area of fuel contact with an oxidizer and enhances the completeness of chemical conversion in the process of explosive charge detonating.

Ignition of pyrotechnic compositions with continuous naer ir lasers

Keywords: laser ignition process, pyrotechnic compositions, blasting cup, ignition, ignition composition

The process of laser ignition of two pyrotechnic compositions used in the blasting cup: KClO4/Pb(CNS)2/PbCrO4 and Pb3O4/ Si has been studied. Lasers with continuous pumping and fiber delivery of radiation at wavelengths of the near infrared range were used: 0.98 μm and 1.56 μm. The ignition delay time was measured at a laser spot diameter of 600 μm and at a laser radiation power of 0.1-10 W. It is established that the delay time for ignition depends on the nature of the composition, on the power of the laser radiation and on its wavelength. The composition of Pb3O4/Si ignites 5-8 times faster than the composition of KClO4/Pb(CNS)2/PbCrO4 . The ignition delay time is proportional to the power of the laser radiation to the power of minus 1.4-1.5. At a wavelength of 0.98 μm, the ignition time is 2-3 times shorter.

Determination of the mass of the charge in the parameters of the discharge funnel and compression zones of up in the clay under water

Keywords: charge, depth, clay, radius, release, area, explosive

At present, the formulas for calculating the charge to foundation of the apparent explosion crater and the compressed camouflage area in underwater clay are not yet available. It is necessary to apply the principle of geometric uniformity with equivalent depth the standard in clay, in order to analyze the dependence of the relative parameters of the apparent explosion crater and the relative radius of the compressed camouflage area when camouflage explosion into the depth charge. Based on these dependencies it is possible to establish the formula for calculating the charge in different conditions of the depth charge.

Features of development of mineral deposits of the Аrctic territories with the use of blasting

Keywords: the Arctic, the Arctic zone of Russia, the Arctic shelf, mineral-resources, solid commercial minerals

Distinctive feature of the modern range of industrial PVV around the world is extremely high level of production and use of explosive ANFO and EVV mixes, as safest, more environmentally friendly and economic PVV. Experience of use of energy of explosion in mining industry and a tendency of improvement of equipment and explosive technologies testifies to an exception of the use of individual brisant PVV, as expensive, toxic, dangerous in the address and practically not suitable for the mechanized technologies. Use of the high-quality porous ammonium nitrate (PAN) allows to cut a specific expense of PEVV in view of lower density of a granule the PASS, and also to decide a number of questions with ecological action of mass explosions that is important at development of mineral resources in the Arctic zone.

Short-circuit protection devices based on high-speed explosive type switches

Keywords: protective device, short-circuit, current-limiting device, high-speed explosive type switch, fusible switching element, inductionless resistor, special reactor.

In the article, short-circuit protection devices based on high-speed explosive type switches are considered: a current-limiting device for 220 kV (CLD), providing a deep limitation of short-circuit currents (SCC) in 220 kV electric networks (operating time in the current limiting mode, not more than 2 s) and a high-speed protective device for 110 kV (HSPD), which continues the idea of ultra-fast limitation of short-circuit currents, but without a long current-limiting mode (disconnects the network in a not more than 0.01 s, thereby excluding the shock current in the first half-wave since the emergence of the SCC). Equivalent schemes of the developed devices are presented and their basic elements are considered. The research of their work was conducted, which showed the prospects of the developed circuits as protective devices of the new generation. The developed devices meet all the requirements for the devices of the new class, and can become one of the key components of the safety of electric networks in the future.

Seismic impact of mass explosions on quarry objects at alternating temperatures of the massif

Keywords: mass explosion, parameters of explosive charge, seismic action of explosion, explosion seismicity factor, thawed and frozen massif

Based on a significant number of instrumental observations of mass explosions conducted at various quarries of the Udachninsky GOK, it was proposed to use the explosion action index equated to the proportionality factor equal to 1.5 for large distances from the investigated object to the locations of mass explosions. This coefficient of proportionality K1.5 can be taken as the seismicity factor of the explosion, which characterizes various technological and natural factors of environmental influence, including the thawed or frozen state of the rock masses studied.

Forecasting the size of the zone of influence of the explosive noise of the explosion in open cast mining

Keywords: safety of blasting, sanitary protection zone, air shock wave explosions sound pressure level, impulse noise high energy, sources of impulse noise is high energy, the noise from the explosions

In article the assessment of admissible size of a level of sound pressure and admissible size of superfluous pressure in a shock air wave on influence of the noise caused by industrial explosions, on the people who are being on open space outside a sanitary-protective zone of the mountain enterprise, as well as on animals and birds on farms and in reserves is executed. The admissible size of superfluous pressure and admissible level of sound pressure are accepted in view of requirements of state standards operating in Russia and normative documents. At definition of admissible sizes of superfluous pressure and a level of sound pressure it is considered, that explosions under the acoustic characteristics and a level of display of noise, are short-term sources of pulse noise of high energy. The recommendations resulted in article, can be used at definition of the sizes of a zone of influence of explosive noise on the open space for people, animals and the birds who are being abroad established for mountain enterprise of a sanitary-protective zone.
