Abstract
The analysis of the mineral base of graphite of the Ukrainian shield with the use of geological and economic eassessment methods was carried out. Directions of the rational development are outlined. The main problems of sustainable development of graphite mineral raw-material base in modern conditions are determined. Geological and technological factors of economic value of graphite deposits and occurrences are characterized. A scheme of comparative assessment estimation of graphite deposits was proposed. This scheme allows to establish the most promising objects for further exploration in the initial stages of mineral deposits prospecting. The analysis includes the main geological, economic, technological and industrial factors of economic value of graphite deposits, such as reserves / resources, graphite content in ores, depth of ores, exploration degree and complexity of the deposit and others. The following methods were used in the work: the method of rapid assessment of the minerals value for determining the potential economic value of objects and the method of scoring. At the first stage, the deposits and occurrences included in the state balance, were ranked according to geological and industrial parameters. Each of the parameters rated according to its qualitative characteristics. The number of points obtained for graphite deposits with proven development efficiency (Burtynske, Balakhivske) and the developed field (Zavalivske) were used as optimal indicators. According to them, the most promising for further exploration works graphite occurrences with the best geological and industrial indicators were selected. The commodity value of these deposits was calculated using the method of coefficients. The results of the calculation were also taken into account for determining the most promising deposits for investment. According to the obtained data, a map of potentially promising graphite deposits of the Ukrainian shield was constracted.
