Outline
The mining of building material quarries generally suffers from problems such as the use of high-quality resources for low-end applications and the indiscriminate mixing of superior and inferior materials, resulting in inconsistent product quality, diminished value, and severe resource waste. To address this, taking granite as the research object, a multi-dimensional comprehensive evaluation system for the optimal use of granite was constructed. This system comprised four first-level indicators, namely appearance quality/chemical performance, physical and mechanical properties, economic benefits, and ecological benefits, along with 19 second-level indicators. Concurrently, a decision model for the optimal use of granite was established, integrating multi-dimensional factors including physical and chemical properties, economic benefits, and environmental impact. To verify the practicability and reliability of the model, Yunfu granite, Luotian granite, and Golden Ma granite were selected as case studies. The results determined that the optimal uses for Yunfu granite, Luotian granite, and Golden Ma granite are natural stone for plazas (roads or pavements), natural stone slabs for furniture, and pebbles and crushed stone for construction, respectively. Further comparative analyses of the calculation results were conducted using the VIKOR method and the grey correlation degree method, which confirmed the feasibility of the AHP-EWM-TOPSIS decision model. Meanwhile, sensitivity analysis verified that the proposed AHP-EWM-TOPSIS decision model possesses good ranking stability. The research results can provide a scientific basis for the optimal use planning of granite resources. The constructed decision model and the developed decision analysis tools have broad application prospects and can effectively support the optimized allocation of granite products.
