Freezing liquid stopping device and freezing liquid stopping method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of soil water conservation mining, in particular to a freezing liquid stopping device and a freezing liquid stopping method. Background technique [0002] At the current mining site, there are often water resources in the soil that may affect the mining operation. For example, in the mining operation site, the groundwater resources in the mine are very rich. When the groundwater gushes out, it may reduce the mining efficiency or even cause the mining operation Stop, and may also cause safety hazards, especially in the mining operations of soft rock slopes, which are common types in open pit mines. Flowing water can easily cause topographical damage to soft rock slopes, and then dangerous situations occur. [0003] In response to this problem, the conventional technical solutions in the industry in the past include: adopting dewatering to remove water from the work site, performing curtain grouting to form a ...

Problems solved by technology

However, these technical solutions all have obvious defects. First of all, for the method of draining precipitation, the water resources at the operation site are often huge. Using this method needs to consume relatively large resources, resulting in a substantial increase in operating costs, and it will affect The distribution of water resources in the entire region will affect the water level, which will cause serious damage to the local ecological system including the surface vegetation, which is not conducive to the sustainable development of the ecology. Especially, in Inner Mongolia and other grassland areas rich in mineral resources, in order to protect the local In grassland ecosystems, it is particularly important to realize soil water conservation mining; and for the method of curtain grouting, a large amount of grouting materials are required to form a water-blocking curtain, which is also expensive, and the formed water-blocking curtain is limited to areas with little water. In areas with too much water, it is difficult to form effective barriers, and grouting materials will also have an adverse impact on the ecological environment; similarly, setting up local concrete waterproof walls also requires a large amount of concrete materials, and it is also difficult to Many areas form an effective barrier, and the formed concrete is difficult to handle, which will also have an adverse impact on the ecological environment
