Creating classification of ways to use coal mining waste

Purpose. To analyze innovative ways of utilizing coal mining waste. To identify the most relevant ways of using waste based on the economic indicators of the cost of using coal mining waste utilization technologies and their impact on the environmental condition of coal mining regions. Methods. In preparing for the research, the following tasks were set: to analyze the problem and assess the main ways of using coal mining waste; to identify the main advantages and disadvantages of using a particular method of using coal mining waste; to identify the most promising ways of using coal mining waste today. Findings. The article provides a critical analysis of scientific papers and Internet resources on innovative ways of using coal mining waste. The advantages and disadvantages of using coal mining waste processing technologies are substantiated. Originality. The interrelation of classifications of methods of utilization of coal mining waste depending on the lithological composition of the waste mass and its physical and mechanical properties is established. The necessity of using coal mining wastes is proved, taking into account the environmental indicator of their impact on the adjacent territories. Practical implications. The data obtained indicate the use of coal mining waste as a valuable raw material for the construction industry and man–made deposits of valuable rare earth elements. The market value of rare earth elements and their practical application in industry are considered. The main areas of use of waste heaps are highlighted – extraction of valuable components and as a source of valuable raw materials for the construction industry. Attention is focused on the technological, economic and social aspects of the feasibility of industrial development of waste heaps, as well as the main reasons that currently complicate this process. Keywords: coal mining waste, coal mining waste utilization technology, rational use of coal mining waste, assessment of the environmental method of waste processing
