Selection and justification of drilling and blasting parameters using genetic algorithms

Purpose. Using experimental and theoretical studies to justify the rational location of charges various types their technological parameters in fan, taking into account physical mechanical properties structural features rocks mountain massif. Methodology. In experiments, an improved method geostructural analysis was used obtain detailed data on properties, block structure massif, type direction development crack systems. Identification systems, density, intensity, systems is carried out petrographic sections using microscopic analysis, these are calculate average indicator cracking coefficient, while funneling – anisotropy coefficient. The justification number each fan performed methods genetic algorithms developed software product. Findings. coefficient uranium ores calculated, which 78 cr/sm2 1.4, respectively. According mathematical models product, optimization problem solved algorithms, determined main priorities: charge according massif diameter well, helps limit oversized blocks reflected ore. Originality. regularities established change from nature distribution microcracks (cr/sm2) quartz grains, present ore a linear law, output (in %) during destruction polynomial law. For first time, optimal wells, rock, its strength fissure, geometric deposit, were based constructed Practical value. indicated results will form basis for substantiation resource-saving seismically safe breaking strong complex extraction iron by energy explosion mines.
