The development of the phosphate mine in the Bled El Hadba region represents a pivotal move to meet increasing demand. This study aims to develop a comprehensive 3D geographic model of the deposit, estimate its phosphate reserves, and assess the parameters and characteristics for effective exploitation. Utilizing the block model method in Surpac 6.6.2, a detailed analysis is achieved that supports informed decision-making for sustainable resource management. This approach underscores the importance of technological innovation in the strategic planning and efficient utilization of mineral resources. The results revealed total reserves of 425,304,000 m3, equivalent to 893,138,400 tons, with an average grade of 21.65 %. The stripping ratio was determined to be 3.3:1. These findings provide valuable insights into the deposit’s potential and the optimal depth range for extracting the highest concentration of P2O5. For detailed extraction planning and estimating P2O5 concentration over five-year periods from 2023 to 2066, with an average annual phosphate ore production of 20.7 million tons, Minesched software was utilized. This comprehensive approach ensures efficient resource management and maximizes the economic return from the deposit. These findings have profound implications for enhancing both the efficiency and sustainability of Algeria’s mining industry. By securing a consistent supply of phosphate products, particularly for agriculture, this research addresses the rising demand for phosphates. Additionally, the data can inform strategic planning, enabling optimized resource extraction and reduced environmental impact. This contributes not only to the immediate needs of the industry but also to the long-term economic and ecological sustainability of the region. Ultimately, the study supports sustainable development by balancing industrial growth with environmental stewardship, ensuring that future generations can continue to benefit from these vital resources.enArticle
