АНАЛІЗ ВИКОРИСТАННЯ ПРОМИСЛОВИХ ВІДХОДІВ ДЛЯ ФОРМУВАННЯ ЗАКЛАДНИХ МАСИВІВ У ТЕХНОГЕННИХ ПУСТОТАХ

Abstract

Purpose. The objective of this study is to examine and compile a list of the most common types of backfill materials based on the analysis of successful backfilling practices in the development of technogenic cavities in mineral deposits in Ukraine. Methodology. The study employed theoretical analysis, information systematization, and data synthesis related to the research problem. It investigated the characteristics of different backfilling methods and the experience of using backfill materials in various countries where backfilling practices have been implemented. The study relied on data from government statistics, waste disposal sites, regional environmental reports, and the environmental passport of a leading region in industrial waste accumulation. Results. The study determined that insufficient attention has been given to the analysis and study of various types of industrial waste and their potential utilization as backfill materials for filling technogenic cavities in Ukraine. The main advantages and disadvantages of existing backfilling methods commonly used in mining practice have been analyzed. Among these methods, solidifying backfilling was found to be the most promising in terms of geotechnical stability and reliability of the artificial mass. Based on the analysis of successful backfilling practices, a priority list of the most common types of backfill materials has been made. Additionally, the study examined the volumes of waste accumulation and occupied areas for different types of backfill materials using a leading region as an example. Scientific novelty. The study has identified the most practical and characteristic types of natural and technogenic backfill materials that can be considered for the development of backfilling practices for technogenic cavities in Ukraine. Practical significance. The study of natural and technogenic waste materials, their accumulation parameters, and characteristics is an important step towards the development of effective backfilling practices for technogenic cavities and subsequent restoration of disturbed territories.
