The possibility of using slags as recultivating material, defining, primarily, by the water solubility of the composition components, has been studied. From the results of the investigation of various types of slag materials, their compositions and aqueous extracts in distilled water, the data on variation of pH-value and element migration into quarry and distilled water are obtained. The recultivation process of mined-out space is developed with the use of technogenic waste materials as stowage mixtures on the basis of the results of the investigations taking into account the engineering-geological conditions of the plant and feedstock provision.
