The article presents a methodology for resource estimation of a phosphate deposit based on block modeling. The advantages of applying regularization and geometric optimization algorithms for mineable units are demonstrated, ensuring more accurate differentiation of ore grades and a reduction in ore losses and dilution. A comparative analysis is conducted on the excavation of pit benches with varying slope angles and equipment configurations. It is established that a block size of 5m ×5m provides an optimal balance between model accuracy and equipment productivity. The most effective slope angle of the benches is determined based on equipment performance and cost-efficiency. The results contribute to improving the accuracy of resource forecasting and the overall economic viability of deposit development by significantly reducing operating costs and enhancing the quality of extracted material. The study outlines practical approaches to selecting appropriate equipment configurations for different mining scenarios. Special attention is paid to the influence of excavation geometry on the performance of hydraulic excavators. The methodology proposed can be applied to similar deposits with complex morphology. The research findings may serve as a basis for developing more adaptive and data-driven mine planning strategies.
