Underground water pollution prevention and control method for ionic rare earth mining process
The invention discloses a groundwater pollution prevention and control method for an ionic rare earth mining process, belongs to the technical field of mining, and solves the problem that the surrounding environment is inevitably irreversibly changed by anti-seepage means such as an anti-seepage curtain and anti-seepage cloth of the ionic rare earth mining process in the prior art. According to the technical scheme, the method comprises the following steps that according to geological conditions and mineral deposit distribution of a rare earth mining area, thermosiphons are spread in a freezing barrier area needing to be frozen, and every two adjacent thermosiphons are arranged in a spaced mode; a working fluid medium is injected into the thermosiphon; the matrix around the ore deposit is frozen through the thermosiphon, and a frozen soil type freezing barrier is formed; the temperature of the thermosiphon and the surrounding matrix is monitored, and the integrity of the frozen soil type freezing barrier is kept. The method has the advantages that a complete freezing barrier is formed at the edge of a mining area, pollutant seepage is prevented, and irreversible change to the surrounding environment is avoided.
本申请公开了一种离子型稀土开采工艺地下水污染防控方法，属于采矿技术领域，解决了现有技术中离子型稀土开采工艺的防渗帷幕、防渗布等防渗手段不可避免地对周遭环境造成不可逆的改变的问题。本申请的技术方案中，包括以下步骤：根据稀土采区的地质条件和矿床分布，在需要进行冻结的冻结屏障区域内遍布热虹吸管，相邻的两个热虹吸管之间间隔设置；向热虹吸管内注入工作流体介质；通过热虹吸管对矿床周围的基质冷冻并形成冻土型冻结屏障；监测热虹吸管及其周边基质的温度，保持冻土型冻结屏障的完整。本申请的优点在于：在开采区边缘形成完整的冻结屏障，防止污染物的渗出，并且不会对周遭环境造成不可逆的改变。
