Abstract

The increasing development of mineral resources have posed a significant challenge in the safe disposal of large volumes of tailings with high water content. This study aims to investigate the engineering properties and drainage consolidation characteristics of manganese tailings and assess the feasibility of vacuum drainage technology in enhancing the strength of manganese tailings with high water content and improving the stability of manganese tailings dam slope. To this end, an indoor model test apparatus was developed to separate mud and water in manganese tailings soil and a scaled model was established for indoor vacuum drainage consolidation. By varying parameters such as the number of drainage channels and the site slope ratio during the application of vacuum pressure, the study examined the drainage volume and rate consolidation patterns of manganese tailings soil. Settlement deformation data at various distances and depths from the drainage body were monitored to identify the impact range of the drainage consolidation process on the surrounding soil. Penetration tests were conducted before and after consolidation to clarify the role of vacuum drainage consolidation in improving the mechanical properties of manganese tailings soil.
