Freezing liquid stopping device and freezing liquid stopping method
The invention discloses a freezing liquid stopping device and a freezing liquid stopping method. A refrigerant output by a refrigeration module is circularly transmitted along a refrigerant transmission channel, so that surrounding liquid is solidified, a freezing liquid stopping layer for blocking the flowing of the liquid is formed, the influence of underground water on exploitation operation isavoided, and particularly, for a soft rock side slope area of an open pit mine, the structural stability and water resistance of a side slope with underground water frozen are greatly enhanced. A physical method is adopted, materials for forming a water-blocking structure do not need to be consumed, only low-power operation is needed for maintaining freezing after the freezing liquid stopping layer is completely formed, the cost is low, the effect is excellent, and the device and the method are particularly suitable for exploitation operation in a high-cold environment. Most importantly, whenthe exploitation is finished, water resources can be restored to the original state after the freezing liquid stopping layer is melted, the situation that the water level is greatly reduced by drainage of precipitation is avoided, soil fixation and water control are realized, a green exploitation operation auxiliary scheme beneficial to ecological sustainable development is realized, and a greatsignificance is achieved for vegetation protection in a steppe region rich in mineral resources.
本发明公开的冷冻止液装置及冷冻止液方法中，制冷模块输出的冷媒沿冷媒传输通道循环传输，使周围的液体凝固并形成阻隔液体流动的冷冻止液层，避免了地下水对开采作业的影响，尤其是对于露天矿场的软岩边坡区域，边坡地下水被冷冻后的结构稳定性和隔水性大大增强。其采用的是物理方法，无需耗费形成阻水结构的材料，当冷冻止液层完全成型后，维持冰冻只需低功率运行，成本低但效果优良，特别适合高寒环境下开采作业。最重要的是，待完成开采，水资源在冷冻止液层融化后可恢复原状，不会如疏干降水一般造成水位的大幅下降，实现固土控水，是有利于生态可持续发展的绿色开采作业辅助方案，对于在矿产资源丰富的草原地区的植被保护具有重大意义。
