The Instability Mechanism of Soil-like Slope under the Action of Acid Corrosion in Open-Pit Copper Mine

Abstract:

Combined with the engineering geological conditions and geological characteristics of soil-like slope in a certain open-pit copper mine, based on the experiments and theoretical analysis, the instability mechanism of soil-like slope under the action of acid mine wastewater is researched. Because the acid wastewater goes into the weak structural plane, reacting with the constitutional materials and fillings in slopes, the react change the microstructure of the rock and soil, and replace, dissolve the components, causing the cohesion and internal friction angle of slope reducing eventually and slope failure.
