Abstract:
Purpose. To develop the algorithm for selecting ways of rehabilitation of waste dumps at the end of their operation.
Methodology. Search and analytical work was carried out. We used the standard method of preparation of the decision-making algorithms.
Findings. The article presents a brief analysis of waste dumps of coal mines as a source of human impact and anthropogenic mineral deposits. After expiration of waste dumps exploitation raises the question of choosing the directions of their further use. Mine dump can be disassembled by the backfilling rocks in the areas of surface subsidence or by filling the mined-out space, reclaimed or used as a source of valuable components (carbon, alumina, rare earth metals, etc.). Therefore, we apply the principle of diversification in the treatment of waste dumps, providing variation in ways of their rational use. Selection of the most effective way and technology of dump use requires a system of defining criteria, i.e. the parameters of the mine dump, causing the feasibility of its development, or rehabilitation, followed by the inclusion of it into the ecological system of natural areas. Basic information for the selection process should be provided by its technological certificate. The block diagram presented in the article shows the algorithm for selection of right waste dumps treatment technologies. We consider the required information sources for the proposed algorithm: standard, typical and specialized, with step by step expansion of the data in waste dump database.
Originality. For the first time the algorithm of diversification of waste dumps treatment technologies has been developed in the form of a flowchart and levels of its information management have been suggested.
Practical value. The proposed approach to diversification of the technology of waste dumps treatment will contribute to effective management decision making at acting and liquidated mining companies and in the field of Post Mining.
