Influence of ammonium nitrate grade on the efficiency of the industrial mixed explosive compositions

Keywords: on industrial composite explosives, ammonium nitrate fuel oil (ANFO), ammonium nitrate, porous ammonium nitrate (PAN), emulsion explosives, blasting operations

The results of researches on industrial composite explosives applied in mining enterprises have shown that nowadays, when performing the blasting operations in different mining and geological conditions, the most effective and safe explosives are porous ammonium nitrate (PAN) based industrial explosives such as ammonium nitrate fuel oil (ANFO) and PAN based emulsion explosives. The performances of PAN enable producing more effective industrial explosive compositions and obtaining less toxic explosion products due to achievement of the optimum stoichiometric oxidizer-to-combustible ratio in industrial explosive composition.

On the assessment of the efficiency of explosives by the method of "plate-witness"

Keywords: explosive charge, specific impulse of explosive influence, polytropy coefficient of explosion products, relative efficiency of explosive

The theoretical analysis of estimation of working capacity of explosives by the "plate-witness" method is presented. It is shown that it is impossible to carry out a correct assessment of its performance only by the breakdown ability of explosives. It is necessary to additionally determine the detonation rate and polytropy coefficient of the explosives detonation products. At the same time, if the detonation velocity can be measured simultaneously with the experience of the penetration of the witness plate, then additional experiments using special devices and techniques are necessary to determine the polytropy coefficient of the explosion products. In addition, the dependence of the strength and deformation properties of metals on the level and rate of increase in the load reduces the accuracy of determining the efficiency of explosives using the method of "plate-witness". However, in the case where the detonation rate and the polytropic coefficient are known, the assessment of the relative efficiency of the explosive is easily carried out on the basis of known thermodynamic criteria without experiments on the penetration of the plates.

Pyrotechnic compositions, nanothermites and primary explosives in laser initiating system

Keywords:ignition, laser initiation, pyrotechnics, initiating explosives, nanoaluminium, nanothermite, laser radiation, detonation

The process of ignition by a continuous infrared laser with a wavelength of 0.98 μm of the pyrotechnic composition Pb3O4 / Si, initiating explosives of lead and azide lead azide, their mixtures with 0.5 % nanoaluminum and nanothermite based on nanoaluminum and nanosized copper and bismuth oxides was studied. The ignition delay of these materials was investigated at a laser radiation power of 0.1 to 10 W. It has been established that the ignition delay time ti decreases with increasing power P of the laser radiation according to a power law: ~ P– k, where k is a constant in the range 1-10, depending on the material. It is shown that the addition of 0.5% nanoaluminum in the TRW allows to lower the initiation threshold by almost two orders of magnitude. Among the materials studied, nano-thermites demonstrated a noticeable advantage in sensitivity to laser radiation and the rate of initiation.

Development of civilian industry products based on salvageable ballistite-type powders and propellants

Keywords: salvageable powder, propellant, industrial explosive, one-piece body, sensitizer, retarder, charge, detonator, accumulator

The result of investigations carried out by JSC “NIIPM” was the formulating and processing techniques development of granular and water-filled industrial explosives based on salvageable ballistite-type powders and propellants with a maximum use of existing facilities in the industry enterprises. Some methods have been found for reducing the burning rate of salvageable powders by adding fire retarder and filling agents to their compositions. High-performance downhole pressure accumulators have been constructed on the basis of powders with a low burning rate (U = 3  4 mm/s at Р = 10 MPa). The in-downhole running time of such accumulators measures up to 15-30 min at a depth of 1500-2000 meters. A processing technique has been proven which involves the production of seismic charges, boosters, shaped charges of different typical sizes from the salvageable powders and propellants with a wide range of detonation wave power. Field tests of developed charges showed that the operating reliability of the industrial explosives based on ballistite-type powders and propellants is highly competitive with that of TNT containing industrial explosives. All articles of civilian industry production based on salvageable ballistite-type powders and propellants are provided with the prepared design and process-control documentation and permitted by Russian Federal Service for Ecological, Technical and Atomic Supervision (Rosthekhnadzor) for industrial application.
