Baranov Y. Feasibility of technological parameters of selective-gross mining of alluvial titanium-zirconium deposits

This Thesis is devoted to solving urgent scientific-and-practical problems of feasibility of technological parameters of selective-gross mining of alluvial titanium-zirconium deposits of Ukraine by means of using conformity to natural laws of heterogeneity of mineral area extent in the line of mining and recovery process during opencast mining to provide selective-gross recovery and also productive work of mining transportation to afford separate warehousing of ores according to their mineral composition. For the first time mechanism of changing horizontal and vertical heterogeneousness of mineral spreading in ore deposits in the line of mining was established. Increased mineralization zones of different component were also determined together with the mining-geometric analysis of colliery field using geoinformational and geological modeling. Developed mathematical model of moving dump trucks and wheel loaders will make it possible to effectively define optimal speed along the colliery road having different relief using minimal fuel rate. Ratio-navigation system for technological and technic parameters of the open-pit transport has been developed where theoretical model of defining optimal speeds for dump trucks and technical decisions as to managing cargo traffic in real time mode in accordance with the requirements for selective-gross mining of ores has been tested and put into operation. All these results were used for "The standard Operating Procedures for Using Technology of Partial Selective Mining of Partial Selective Mining of Titanium-Zirconium Ores on the Basis of Three-Dimensional Geological Models" implemented by Open Joint-Stock Company "Ukrgiproruda" and in "Guidelines for increasing the efficiency of Technological Parameters of Colliery Transport While Extracting Titanium-Zirconium Ores" introduced by State Engineering Research Institute "Krivbassproekt". Estimated economic effect due to these offered technologies in Volnogorsk GMK comprises 4476.425 grivnal per year.
