湖南新邵县谢家山金锑矿区水文地质特征分析

Analysis on Hydrogeological Characteristics of Xiejiashan Gold Antimony Mine in Xinshao County of Hunan

本文对谢家山金锑矿区水文地质条件进行分析与总结,认为矿区属裂隙充水矿床,主要充水水源为浅变质岩裂隙含水岩组,充水方式主要为顶、底板分散滴入或渗入。采用"大井法"和"比拟法"对谢家山矿区李家冲矿段进行矿坑涌水量预测,估算矿坑涌水量均小于300m3/d,属小水矿床,矿区水文地质条件简单,能为矿山开发利用提供水文地质依据。

This paper analyzes and summarizes the hydrogeological conditions of the Xiejiashan gold-antimony mining area.It is believed that the mining area is a fractured water-filled deposit.The main water source is shallow metamorphic rock fractured water-bearing rock group,and the water filling method is mainly scattered dripping or infiltration of roof and floor.The"big well method"and"comparison method"are used to predict the pit water inflow in the Lijiachong section of the Xiejiashan mining area.It is estimated that the mine water inflow is less than 300m3/d.It is a small water deposit with simple hydrogeological conditions in the mining area,which can provide for mine development and utilization.
