Similarly, Hartman and Mutmansky (2002) define waste as the material that accompanies the ore and needs to be removed to enable access to the ore, and then disposed of in a controlled manner.<\/span><\/p><p>\u00a0<\/p><h3><b>Strategic Importance of Waste Disposal<\/b><\/h3><p><span style=\"font-weight: 400;\">Therefore, waste rock disposal throughout the mine&#039;s lifecycle is a strategic and high-impact operation. Besides representing one of the largest operating costs, how waste rock is managed directly influences the project&#039;s economic viability. The waste-to-ore ratio (REM) defines the minimum economically viable grade, directly affecting mineable tonnage, production scale, CAPEX, OPEX, cut-off grade, Net Present Value (NPV), rate of return on investment, and payback period, as noted by dos Santos (2011).<\/span><\/p><p>\u00a0<\/p><h3><b>Factors Influencing the Quantity and Disposition of Waste<\/b><\/h3><p><span style=\"font-weight: 400;\">Several factors influence the amount of waste rock to be removed from a pit, impacting the selection of the area for its disposal. Selecting a waste rock pile (WRP) site involves analyzing land availability, physical constraints, environmental impacts, and socioeconomic and political considerations.<\/span><\/p><p>\u00a0<\/p><h3><b>Geotechnical Criteria and Detailed Design<\/b><\/h3><p><span style=\"font-weight: 400;\">Once the site is defined, geotechnical criteria become essential to ensure the pile&#039;s stability and safety over time, avoiding technical problems and economic losses. Developing the detailed design of the PDE requires a sequence of geotechnical studies that gradually increase understanding of the ground conditions (Figure 1).<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-314eefa e-flex e-con-boxed e-con e-parent\" data-id=\"314eefa\"

style=\"font-weight: 400;\">Waste rock piles are composed of heterogeneous materials from different lithologies and present a wide range of grain sizes, from large blocks to fine soils. The foundations can also vary, from firm ground to soft soils with low bearing capacity.<\/span><\/p><h3><b>Geotechnical Risks and Control Practices<\/b><\/h3><p><span style=\"font-weight: 400;\">Waste rock disposal poses significant geotechnical risks to the safety of people, equipment, and structures.
