摘要

目的。研究氢氧化钠、碳酸氢钠、碳酸钠等钠基悬浮液对煤矿矸石开采过程中自燃过程中和作用的有效性。在考虑外部环境因素的情况下,建立悬浮液对废物贮存化学元素影响的依赖关系。为解决既定任务,采用理论和实验室对比分析的方法,研究了悬浮液对煤矿选矿过程中获得的废渣自燃氧化还原反应机理过程的影响。介绍了利用学生t判据的相关分析,对废渣与钠溶液相互作用的实验研究结果进行合理处理的方法。根据库存中的活性化学元素:黄铁矿、硫和氧化铁与环境的相互作用,研究了库存的自燃机制。钠基浆料在处理库存时参数的选择与优化,通过使活性化学元素结晶并填充其多孔结构来解决库存处理过程中自燃问题。科学的新奇。建立了废岩体热氧化过程受环境影响的依赖关系。证明了消除自燃点作为环境污染的主要因素的方法和技术的方便性。本文提出了一种新的权宜之计方法和方法,既能对废矿区的经济效益进行评估,又能对生态效益进行评估,有助于改善废矿区的生态经济状况。实际的含义。它包括拟订关于消除采矿废料自燃的方法和技术的建议。提出了确定含有钠基的惰性物质(悬浮液)所需的定量和定性组成的方法,以消除废物外源燃烧过程中的含硫区。已经拟订了关于使用这些手段和方法的建议。

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