Comparative technical-economic analysis of application the dumping process of fly ash and slag from thermo power plants, heating plants and metallurgical plants by conventional procedures and backfilling to the 'place of origin' i.e. in the abandoned mined areas of mines with previous preparation and application of modern dumping technologies, reclamation and remediation and modern methods of protection

Abstract

Previous experiences in production and processing of metals, nonmetals and coals, have shown the significance of problem of dumping the waste materials on the surface of e terrain, with all following consequences on the agricultural land and eco system as whole. Since, in this case is delaying with the material in annual amount of several millions m3, which is almost certainly in some measure poisoned, and not rarely cancerous, the question of its dumping in nature (mostly on the agricultural land ore in the close neighborhood, closed to the facilities which produce it), and with it interruption of whole eco system must be treated with appropriate care. Therefore, the process of dumping such materials presents significant problem, which demands ecologically acceptable and economically sustainable solutions.
