“…Therefore, diversification of the production and supply of germanium in other worlds countries is an urgent task for the world community. Today, the market of Ukrainian Germanium can make a significant contribution to the corresponding needs of the European and world economy [17]. At the state level, the need to develop the deposit is confirmed by the President's order and relevant resolutions of the Cabinet of Ministers of Ukraine.…”

The article is devoted to determining the resource potential of Ukraine in supplying industry with germanium. Statistical information on the potential content of germanium in various types of mineral raw materials located on the territory of Ukraine is summarized. The trends of the world market of germanium consumption in industry have been established. The value of the average content of germanium in coal deposits of the Lviv-Volynsky and Donetsky basins is given. It has been established that the greatest potential for germanium extraction is found in lignite deposits, the content of the valuable mineral in which can be ten times higher than that of hard coal. According to the results of research, germanium is found in the condition standards in ferruginous quartzites of the Annivske deposit of Kryvbas, Horishno-Plavnenske, Lavrykivske and Bilanivske deposits of the Kremenchuk district. The average content of germanium in ore deposits formed from magnetite, hematite, ribeckite, etc. was also determined. The approximate resource availability of germanium contained in deposits of coal, ore and non-ore raw materials of Ukraine was determined.

Purpose. To justify the parameters of the technological scheme of working out an advanced overburden bench by a bucket-wheel excavator, to reduce the cost of overburden work at Pit 7 of Vilnohirsk Mining and Metallurgical Plant. Methodology. Setting the parameters of the technological scheme of the bucket-wheel excavator was performed by the graphic-analytical method, which involves taking into account the technical characteristics of the mining machine, the physical and mechanical properties of the mining rocks and the stable slope angle of the advanced overburden bench. The substantiation of the effectiveness of application of the technological scheme with a forward trench was made by the technical and economic calculation of the specific costs on overburden works. Findings. The possibility of increasing the height of the overburden bench when using a technological scheme with a forward trench was evaluated. Reasonable parameters of the forward trench, in which the bucket-wheel excavator can develop a forward pit bench with a capacity of 40 m with a stable slope angle of 30°. This allows reducing the amount of mining haulage equipment and reducing overburden costs by up to 50 %. Originality. The minimum slope angle of the overburden slope at the maximum digging height of the ERShR-1600-40/7 excavator, which is equal to 40° at a slope height of 40 m, was established. The dependence of the resulting slope angle of on the re-excavation coefficient of the mining rock mass was established. This makes it possible to assert that when this angle is increased the re-excavation rate will decrease. It was established that at the applying technological scheme with a forward trench in the conditions of Vilnohirsk MMP, the coefficient of overburden re-excavation will be k = 0.09. Practical value. A technological scheme for the development of an advanced overburden bench by the bucket-wheel excavator with a forward trench allows increasing its developed bench height. This makes it possible to reduce the operational cost for overburden works by refuse from haulage mining system with dump trucks.
