The accumulation and discharge amount of coal gangue are substantial, occupying significant land resources over time. Utilizing as subgrade filler can generate notable economic social benefits. Coal coarse-grained soil (CGSF) was used to conduct a series large-scale vibration compaction tests triaxial tests. results indicate that the maximum dry density CGSF initially increases then decreases with increase in fractal dimension. stress–strain curves samples exhibit distinct nonlinear growth pattern. Analysis effect suggests degree should not be lower than 93%. As confining pressure increases, extent failure strength improvement due increased decreases. Additionally, coarse particle content. A modified quadratic polynomial model gradation equation proposed describe after breakage. Based on this, new quantitative index for breakage established. revealed higher greater content lead exhibited size effect, impact sample pressure. relationship analyzed by using logarithmic constitutive model, correlation between parameters newly derived generated. incorporating established, its accuracy validated.

Coal gangue (CG) is one of the most frequent solid wastes in world, and it poses a severe hazard to both human society natural ecosystems. In light progressive increase environmental awareness unavoidable trend requirements sustainable development plan, how efficiently use these vast quantities CG has become an important subject China. Concrete aggregate, which can not only solve pollution but also compensate for scarcity gravel sand resources, cost-effective eco-friendly way utilize resources accordance with strategic green development. However, deal preparation high-quality aggregate needs be targeted research; blindly using concrete may bring some safety hazards. This requires that based on source, distribution, storage, chemical composition, mineral composition problems utilization process, efforts are made open up key routes utilization, provide theoretical guidance high-value environmentally friendly CG. paper summarizes characteristics its impact performance, discusses technical means improve performance concrete, analyzes if current application problem still exists, view gradually realize low-energy consumption bulk utilization. The popularization will accelerate solution brings, certain extent alleviate situation supply insufficient meet demand; today’s research economic significance.
