【技术实现步骤摘要】
本技术涉及一种用于模拟全覆式稀土矿山原地浸矿收液巷道出渗边界渗流规律、测量出渗坡降和收液效果的室内模型试验装置。
技术介绍
目前,“原地浸矿”作为第三代绿色环保的开采工艺,已经在我国南方离子型稀土矿中推广开来。该工艺流程为:先在稀土矿体区域布置注液井网,再通过注液井将浸矿剂溶液注入矿体,矿体中的稀土通过离子交换反应变成稀土离子进入溶液,最后通过收液工程加以回收处理。对于底板深潜的全覆式稀土矿山,一般需要在山体内开挖收液巷道作为收液工程,溶液从收液巷道边界出渗进而收集,其出渗坡降是校核巷道工程稳定安全的重要数据,其收液效果是矿山收液效果的重要评价指标。因此,设计出原地浸矿收液巷道出渗坡降与收液效果试验装置是当务之急。
