Abstract
Aim: This study analyzes the potential for processing coal mining waste in civil and road construction.
Materials and Methods. The research focused on rock dumps from eight mines in the Lugansk People’s Republic. According to current methods, samples of dump rock were collected and analyzed in the laboratory for various properties, including Al2O3 content (up to 22%), total sulfur (up to 4%) in rock samples of varying degrees of metamorphism, indicators of its plasticity, and radiation characteristics (up to 220 Bq/kg).
Results. This study addresses the processing of rock dumps from coal mines in the Lugansk People’s Republic as a source of raw materials for building materials. A brief analysis of existing methods for obtaining various building materials from waste rocks was carried out. The laboratory tests on waste rock samples from several mines demonstrated their potential use in civil, industrial, and road construction.
Conclusion. The research provides a detailed analysis of various indicators and properties of coal mining waste in the Lugansk People’s Republic, including specific effective activity and evaporation coefficient. Findings suggest that the waste rock can be effectively used as raw material in the construction industry, supporting the production of materials for industrial, civil, and road construction.
