JUSTIFICATION OF METHODS AND TECHNIQUES FOR THE ELIMINATION OF SELF-DISPOSAL OF MINING WASTE

Abstract

Purpose. To analyse the processes of spontaneous combustion of mining waste, too study the impact of waste combustion on the environment, to define the main factors that provoke spontaneous combustion of mining waste. Methods. A comprehensive approach has been applied, which includes an analysis and synthesis of literature and experimental data on the problem of spontaneous combustion of mining waste. The current status of spontaneous combustion of mining waste has been analysed. Results. The feasibility of applying methods and techniques for the treatment of waste rock to further prevent spontaneous combustion has been substantiated Scientific novelty. The dependence of the environmental impact on the processes of thermal oxidation of waste rock mass has been established. The expediency of applying methods and techniques for eliminating self-combustion foci as the main factors of environmental pollution has been determined. A new expedient method and method has been proposed that will allow estimating not only the economic effect but also the environmental one, which will contribute to improving the environmental and economic situation of mining regions where mining wastes are deposited. Practical implication. Practical implication consists in the development of recommendations for methods and techniques to eliminate spontaneous combustion of mining wastes A methodology for determining the necessary quantitative and qualitative composition of inert substances (suspensions) containing sodium group to eliminate sulphurous zones of exogenous combustion processes of waste stock has been proposed. Recommendations on the use of these means and methods have been developed.
