Strip mine distributed water resource storage and utilization system and implementation method thereof

Abstract

The invention discloses a strip mine distributed water resource storage and utilization system and an implementation method thereof. The implementation method comprises the following steps: S10, a contour map and a stratigraphic histogram of a mining area and surrounding terrain are obtained; S20, water storage area parameters of the distributed water resource storage and utilization system are planned, and a geomorphic contour line is remodeled; S30, a part of storage and utilization systems are built in the internal drainage operation period of the strip mine, so that resource utilization of part of mine gushing water and rainfall is achieved; and S40, construction of the distributed water resource storage and utilization system is completed during the pit closing period of the strip mine. According to the method, mine gushing water in the open-pit mine production period in the water-deficient area is effectively stored and converted into production water and greening water in time; after a pit is closed, rainwater is stored and called through the height difference between distributed water storage areas and the height difference between the water storage areas and a reclamation area. The volume of a water storage area is used for counteracting the volume of produced resources, so that the elevation of an area reconstructed by internal drainage operation is close to that of an original landform, and geological disasters such as landslide and debris flow are avoided.

Description

technical field [0001] The invention relates to the field of protection and utilization of water resources in open-pit mines, in particular to an open-pit mine distributed water resource storage system and an implementation method thereof. Background technique [0002] A large amount of pit water will be generated during the open-pit mining process, which can be divided into two categories according to the source of pit water: one is atmospheric precipitation directly falling into the mining field; the other is groundwater from bedrock fissures. In order to ensure the safe production of each operating site in the mine pit, the mine gushing water must be drained away in time. Open-pit mines also need to consume a lot of production water and green water in the normal production process. The reality that mine water gushing cannot be kept and production water is extremely scarce has greatly intensified the contradictions in water resource utilization in open-pit mines in water-...

AI Technical Summary

Problems solved by technology

[0003]It is a common practice in open-pit mining to create land through internal drainage operations. The space leads to a large height difference between the inside and outside of the open pit, so the edge area becomes an area with high incidence of geological disasters such as landslides and mudslides
