“…First of all, the domestic germanium market can include producers of germanium coke chemical concentrate, companies developing coal deposits with category "B" (deposits with significant concentrations of germanium), as well as enterprises that produce germanium ash concentrate. In the second and third stages, the market can be composed of enterprises processing germanium raw materials and enterprises consuming germanium and its compounds, which respectively produce hightech products with high added value [18].…”

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.

“…The criterion for assessing the effectiveness of the proposed mining system is the specific cost for strip-mining of 1 m 3 [19,20,21,22]. Therefore, we will calculate all cost items for this stripping site, and based on the obtained data, construct a histogram for calculating unit costs for mining the Zakhidnyi Quarry No.1 site (Fig.…”

The paper examines a complicated non-transport system for mining a gently sloping fireclay deposit using ESH-10/70 dragline excavators. The research purpose is to substantiate the technological scheme of stripping operations and determine their parameters to reduce the strip-mining costs. Theoretical research is performed using the following methods: methods of scientific analysis of theoretical research, as well as practices of project and production organizations; mining-geometric calculations; variant method for comparing and selecting a mining system. As a result, the dependence of the excavator block mining velocity on the entry way width has been determined, which makes it possible to study the relationship between mining and stripping equipment in time. The change in the re-excavation coefficient depending on the width of the dragline excavator entry way has been studied and its rational value has been determined. The practical value of the research results is in the substantiation of an effective system for mining a gently sloping fireclay deposit.

“…The mining of overburden benches [24] is carried out by Caterpillar 365С and Caterpillar 345СL excavators with a shovel volume of 4.8 and 3.2 m 3 , respectively. Rocks from external overburden are haulage to the internal dumps [25] of the pit by Caterpillar 735 dump trucks with a carrying capacity of 32.7 tons, where they are dumped separately from each other in the same order as before development.…”

The article is devoted to the issue of the overburden excavators effective standard sizes substantiation in the conditions of the development of kaolin pits. The influence of the excavator standard dimensions on the total weight of the extraction and loading equipment in the pit at a given annual productivity of the pit was investigated. It has been proven that when the shovel capacity of a hydraulic excavator increases by 7 times from one to 7 m3, the total number of excavators in the conditions of the Rozivskyi kaolin pit decreases by 6.7 times from 20 to 3, and their total metal capacity decreases by 2.3 times from 760 to 348 t. The established dependences of the daily productivity of the equipment and the excavation work cost on the excavator shovel volume allow claiming that scheme where using 5 Volvo EC 750D excavators and 10 Volvo A45 dump trucks is the most effective. The worst performance for all types of costs is the technological scheme using 20 Volvo 350D excavators and 17 Volvo A45 dump trucks. When using 5 Volvo EC 750D excavators and 10 Volvo A45 dump trucks in the proposed scheme, the cost of excavation works up to 34.5 UAH/m3 and is minimal due to the lowest costs for depreciation and repair of equipment, as well as for fuel and lubricants.
