Abstract
Problem Statement (Relevance). Maintaining a given level of quality of the extracted products is a task that occupies a leading position in any production, especially in the extraction of ore minerals. But the requirements for the quality of coal products are no less fundamental, so the issues of dependence and interrelation of the quality characteristics of coal deposits are relevant. Given the indisputable fact that the quality in the subsoil cannot be changed, designers, researchers and technical specialists in production are forced to seek the most effective methods for predicting the quality during the extraction and storage of minerals and improve methods for stabilizing the flow of extracted products. Most studies suggest quality management methods during extraction by averaging or enrichment. Despite the high efficiency, such a process increases the time for obtaining the final product, and, consequently, costs and can be complicated by the high variability of the quality of the products coming from the open pit. Therefore, flow stability plays a key role in obtaining products of a given quality. Objective. Is to analyze the deposit for coal quality distribution dependencies for their further use in the product quality management process. Methods used. The article uses the correlation analysis method to detect distribution dependencies. Originality. The results of the work will allow developing a new approach to substantiating the height of the mining bench, taking into account not only the equipment parameters, but also the discovered dependence. Results. This study includes generalized results of coal sample analysis and identification of quality distribution dependencies within the seam boundaries. Conclusions. A certain dependence makes it possible to most accurately predict the quality of the mineral and thus will allow determining the direction and parameters of mining operations, in which the minimum variation in quality levels will be achieved. Practical Relevance. The application of the results of the work in practice will allow stabilizing the quality level of the products supplied from the open pit, thereby reducing the costs of averaging operations.
