Analyses of hydrogeologic feature and structure in the Xinli seabed gold mine

Hydrogeological studies in mining areas are indispensable for exploration and exploitation of mineral resources.Large amounts of site investigation data show that the Xinli gold mine belongs to a fractured groundwater-filling mine with medium hydrogeologic conditions.According to the distribution features of seepage place,seepage strength and hydraulic links,the whole mining area is divided into seven seepage regions.Based on the geological structure characteristics and rock permeability difference,a hydrogeologic structure model is established for the Xinli mining area.The structure of the rock types,structure models and structure characteristics are also analyzed and described in detail.Some rationalization proposals are proposed to guarantee safety in production.
