SUBSTANTIATION OF THE FEASIBILITY OF CHOOSING A SUSPENSION BASED ON THE SODIUM GROUP IN THE TREATMENT OF COAL MINING WASTE DUMPS

Purpose. To study the effectiveness of sodium group based suspensions: hydroxide, hydrocarbonate and carbonate for neutralisation spontaneous combustion processes waste rock during operation formation coal mining waste. establish dependence influence suspensions on chemical elements stockpile, taking into account external environmental factors. Methods. For solving set tasks, methods comparative analysis theoretical laboratory studies impact mechanism redox reactions heaps obtained in process processing minerals mines were used. The application rational method results experimental interaction mass with solutions using correlation Student’s t-criterion is described. Results. ignition mechanisms stockpile have been investigated, active stockpile: pyrite, sulphur iron oxide environment. selection optimization parameters a slurry when treating will solve problem treatment by crystallizing filling its porous structure. Scientific novelty. environment thermal oxidation established. expediency techniques elimination self-ignition foci, as main factors pollution, substantiated. A new expedient has proposed, which allow estimating not only economic effect but also ecological one, contribute to improving situation regions where wastes are located. Practical implication. It consists development recommendations eliminate wastes. methodology determining required quantitative qualitative composition inert substances (suspensions) containing sulphurous zones exogenous proposed. Recommendations use these means developed.
