摘要
分析地浸铀矿山抽液井地下水位动态变化规律和矿山地下水流场特征对铀资源可持续利用和矿山生产实践具有重要意义。基于抽液井地下水位连续自动监测数据,直观揭示了地下水埋深动态变化特征,并利用Pearson相关系数分析了抽液井地下水位埋深与抽液量的动态响应关系。研究表明,开采条件下抽液井地下水位埋深低于初始水位埋深,并与抽液量呈显著正相关关系;地下水流场分布特征与采区抽注活动密切相关,形成了以井场为中心的区域降落漏斗;井场范围内地下水流场分别形成了以注液井和抽液井为中心的突起和凹陷。
It is significance for the sustainable utilization of uranium resources and the production practice to analyze the dynamic variation law of groundwater level and the characteristics of groundwater flow field in in-situ leaching uranium mines.Based on the continuous automatic monitoring data of the groundwater level of the pumping wells,the dynamic variation characteristics of the groundwater depth were revealed intuitively,and the dynamic response relationship between the groundwater depth of the pumping wells and the pumping volume was analyzed by using the Pearson correlation coefficient.The results show that the groundwater depth of the pumping wells is significantly lower than the initial depth of water level under the mining conditions,and has a significant positive correlation with the pumping volume.The distribution characteristics of groundwater flow field are closely related to the pumping and injection activities in the mining area.An obvious regional depression cones is formed centered on the well field,and the groundwater flow field in the well field forms protrusions and depressions centered on the injection wells and the extraction wells respectively.
