Kalyakin S. The development of the scietific bases of safe manufacturing of explosive works in the gas-bearing massifs of coal mines

Object of researching: system "blast-hole charge - explosion atmosphere" and the processes which accured during detonation of explosives. The aim of researching - development of scientific basics of safe implementation of explosive works in massives of rocks, which consists in modernisation of explosives, rising of preventive properties of explosives, prevention of burn-out of explosives in blast-holes, creation of protection against explosions with the help of methane inhibitors. The methods of researching grounded on using of next methods: experimental detection of explosives' properties, natural modeling in experimental drift of explosion conditions, correlation analysis and mathematical statistics with using of detonation' theory and physics of explosion. Scientific results: depending of regularity of changing of inflammable ability of blast-hole charges, establishing the mechanism of influence of the salt-inhibitor on the igniting ability of the charge and dezrecombination effect in salt-inhibitor during the detonation of explosives. Practical results: the mono-charges and designs of blast-hole charges of safety explosives are developed, which resistant to burn-out, parameters of method of creation of a protective environment with the help of biphasic inhibitors’ system from the salt-inhibitor and the products of an explosion of permissible explosives. Novelty of this work: the regularities of changes in the igniting ability of explosives with the same energy and the likelihood of ignition of an explosive environment from the effect of shock waves and the burning particles of explosives are defined. Experimentally established phenomenon dezrecombination effect of the inhibitor - the unavailability of recombination of radicals on the surface of its crystals with the detonation of explosives safety. Results of work are used in coal mines to ensure the safety of blasting operations in gas-bearing arrays, olso they used by the research and design institutes for the development of technical means and ways to ensure work safety and health of miners, manufacturers of permissible explosives for coal mines in Ukraine. Thus, given the new solution of the actual scientific problem of safe production of explosive works in the gas-bearing rock massive, and improved the work safety in coal mines. Industry of use: the coal industry.
