Organization of processes for complex mining and processing of mineral raw materials from coal mines in the context of the concept of sustainable development

Abstract

Purpose. The research purpose is to form the principles and procedures for developing an organizational concept of complex mining of minerals from coal mines using the example of a promising model of transition of the PJSC “DTEK Pavlohradvuhillia” mines to multi-product production of clean drinking water, utilization of methane, secondary coal from rock dumps and slurry reservoirs, low-grade thermal energy of mine groundwater and associated raw materials from desalination waste. Methods. The instrumental basis of the research is the methodology of the process approach to organizing multi-product activities of an enterprise. In addition, an integrated approach is used, including an analysis of existing experience and available complex coal mining and processing technologies. Findings. The paper presents the research results of the prerequisites for the development of innovative technological solutions related to the integrated use of mineral raw materials formed in the process of coal mining and processing. It has been revealed that at the present stage the technological, environmental and economic aspects of such innovations have been sufficiently developed, while the organizational issues regarding the balanced interaction of multi-product production units have poorly been studied. The necessity has been substantiated, as well as the content and sequence of actions have been determined for the development of an organizational concept of complex mining and processing of mineral raw materials in the conditions of PJSC “DTEK Pavlohradvuhillia”. Originality. The principles and procedures for developing an organizational concept of a multi-product enterprise, formed in the research process, provide further development of a methodological basis for searching and substantiating innovative solutions for complex mining of mineral resources from coal mines. They can be used to assess the efficiency and identify weaknesses in current processes for mining and utilization of coal, thermal energy, methane gas, groundwater, dry residue chemicals from desalination and coal mining waste, and to analyse and make changes to improve performance and reduce costs. Practical implications. The proposed complex of organizational solutions based on the process approach tools to ensure the effective implementation of a promising production model for mining and processing of mineral resources in PJSC “DTEK Pavlohradvuhillia” coal mines provides an opportunity to predict the results and develop development strategies based on various scenarios, analyze the interaction of various factors and their influence on the results of the production complex functioning, while reducing costs for experiments and testing of various production technologies.
