Systematization of the mineral-raw material base of backfill materials and backfill methods in the Kryvyi Rih region

Abstract

Purpose. The research aims to analyse and systematise the mineral-raw material base of backfill materials and backfill methods in the Kryvyi Rih Region based on the study of sources of industrial waste accumulation and types, as well as specifications of backfill technologies. Methods. To achieve the purpose set, an integrated approach is used, including a generalisation of world experience in the use of industrial waste as backfill materials, a study of the register of waste accumulation sites in Dnipropetrovsk Oblast, schematization of the geospatial location of the mineral-raw material base of backfill materials using Google Earth, systematisation and classification of possible backfill methods and combinations of backfill mixture options. Findings. It has been determined that the mineral-raw material base of backfill materials in the Kryvyi Rih Region is insufficiently studied. The scheme of geospatial location of mineral-raw material base sites of backfill materials in the Kryvyi Rih Region has been developed. A general assessment of information data of existing types of backfill materials, their functional purpose, sources of formation and resource reserves is provided. Classification of possible combinations of component backfill mixtures in the Kryvyi Rih Region by types of backfill technologies is proposed. Originality. For the first time, the existing mineral-raw material base of backfill materials in the Kryvyi Rih has been systematised, and a classification is proposed of possible combinations of the backfill mixture component composition by types of backfill methods. Practical implication. Operating the available mineral-raw material base and possible types of backfill methods gives reasons to consider a wide range of resource-saving technologies to minimise geo-ecological problems in the Kryvyi Rih Region.
