HYPOTOXIC POWDER-WATER GEL COMPOSITIONS

In focus of the article is the commercial use of explosive materials, in particular, pyropowders, in Russia. The foreign publications in the sphere of recycling energy components of ammunition are reviewed. The use of water gels with a view to improving ecological properties of energy components utilized as commercial explosives is illustrated. Ecotoxicity of explosion products after blasting of pyropowders, including compositions with the extra content of oxidizer and standard industrial explosive (Ammonite No. 6ZhV) is calculated.

Based on the calculation results, the hypertoxic compositions which have the least ecotoxic products of explosion are determined with regard to detonation characteristics. Using electromagnetic method, the detonation parameters of the developed powder–water gel compositions are compared with the detonation characteristics of Gelpor GP1 and Ammonite No. 6ZhV. The studies exhibit advantages of detonation characteristics of the powder water–gel compositions and some features of their detonation process.

Based on the research results, it has been concluded that the introduction of an auxiliary oxidizer in the powder–water gel compositions has a positive effect on ecotoxicity of explosion products. Judging from insignificant differences in detonation parameters of the studied power–water gel compositions and on the basis of the earlier publications on efficient application of these compositions in mineral mining and rock breakage processes, it is stated that these properties are preserved in the model compositions with the improved ecotoxicity.

Keywords
