Abstract
Relevance. Fracturing of the array is one of the main factors in the formation of quality blocks of decorative stone. Systems of natural cracks form a separate rock and determine the shape and size of structural blocks, which determines the possible output of conditioned block products from the array, the choice of the method of preparing the rock for excavation, the location and direction of movement of the mining front in accordance with the nature, intensity and elements of the occurrence of cracks. To control the quality of decorative stone blocks, modeling and forecasting optimal parameters, it is necessary to investigate the possibility of identifying fractures and then determining their geometric parameters using modern digital equipment. Purpose of research is to analyze the quality management of the extracted rock based on the use of mathematical modeling technologies. The methodology of the work consists in using methods of mathematical modeling, as well as statistical data processing. Results. The practical application of the results is to apply the developed methods in order to optimize the quality management system of the extracted rock and increase its efficiency. As a result of practical research, a rational ledge height of 5.8 m has been established for the conditions of the granodiorite Deposit, which allows to ensure the necessary production capacity of the quarry, high productivity of mining equipment, safety of mining operations, minimal economic costs for mining operations, low production costs and minimal losses of block raw materials. Conclusions. The analysis of the complex of mining operations of mining enterprises allows us to make a conclusion about the need to introduce new technologies into production that would ensure the automation of work, increase the reliability of measurement results and calculations. At the same time, automation should be based on the use of remote methods for assessing the quality of decorative stone, new electronic devices and appropriate software.

Summary
Зависимость точности определения пространственных координат mY от угла конвергенции γ и базиса B при конвергентном случае съемки. The dependence of the accuracy of determining spatial coordinates mY on the convergence angle γ and the basis B in the convergent case of shooting. Зависимость максимального расстояния съемки от базиса B и требуемой точности определения координат точек по оси ординат mY. The dependence of the maximum shooting distance on the basis B and the required accuracy of determining the coordinates of points on the ordinate axis mY. Среди современных методов моделирования пространственной изменчивости показателей качества наиболее перспективными следует считать методы геостатистичного анализа, использование которых с большой степенью вероятности позволяет повысить эффективность процесса управления качеством сырья [2].
