Abstract
Heap leaching structures and waste dumps are the most important mining structures, and paying attention to their stability issues at different stages of construction and operation is important. Investigating the thermo-hydromechanical parameters of the materials of these structures is very important to evaluate stability and geotechnical issues. Various factors affect the thermo-hydromechanical properties of materials, which can change the aforementioned properties and ultimately cause structural instability. Therefore, it is necessary to study the effect of various factors such as pH, salinity, temperature, consolidation, and precipitation (moisture) on the thermo-hydromechanical properties of materials and to investigate their behavior over time. This paper reviews some studies to investigate the effect of the mentioned factors on the thermo-hydromechanical properties of different soils. The results show that the change of some factors like pH affects the hydrodynamic properties of materials, which reduces soil strength parameters. Finally, one may conclude that by examining the hydrodynamic properties of the materials of mining structures and monitoring them over time, a favorable understanding of the behavior of the structure can be achieved, and its behavior can be predicted to some extent.
