新立海底金矿水文地质特征及水文地质结构分析

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

在大量现场调查的基础上,对新立金矿的水文地质特征和水文地质结构进行了详细的分析和论述,指出新立金矿属于水文地质条件中等的裂隙充水矿床。根据矿坑渗水点分布特征、渗水强度及水力联系,将矿区整体划分为七大渗水区域。并基于矿区地质结构特征和岩体透水性的差异,建立了矿区岩体水文地质结构系统模型,对岩体结构类型、结构模型和结构特征进行了分析和描述,最后提出了保障矿山安全生产的合理化建议。

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 groundwaterfilling 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 hydrogeologie 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.
