Distributed underground reservoir and construction method thereof

Abstract

The invention provides a distributed underground reservoir suitable for storing underground water in open mining areas. The distributed underground reservoir comprises a plurality of reservoir bodies located underground, recharge water pipelines and connecting pipelines. Each reservoir body comprises a reservoir bottom, a dam and reservoir fillers, and the reservoir fillers fully fill a semi-closed area enclosed by each reservoir bottom and each dam. The lower ends of the recharge water pipelines are positioned in the reservoir fillers, and the upper ends of the recharge water pipelines extend above the ground. Besides, the reservoir bodies are communicated with one another by the connecting pipelines penetrating through the dams. The invention further provides a construction method of the distributed underground reservoir. The distributed underground reservoir can contain underground water outflowing during mining, occupancy of the ground and evaporation of moisture are reduced, stored superfluous water among the reservoir bodies can be automatically distributed, and storage of water resources in other places during stripping of an open pit mine is achieved by the aid of the recharge water pipelines so that water resources are protected.

Description

technical field [0001] The invention relates to a reservoir and a construction method thereof, in particular to an underground reservoir and a construction method thereof. Background technique [0002] For open-pit coal mining areas in severe cold areas, frequent strong winds, drought and little rain, rich sand deposits, and long-term cold make the land extremely prone to desertification and vegetation to be easily damaged. The development of open-pit coal mines has affected the original groundwater operation system, making the already fragile ecological environment worse, and the protection and utilization of water resources has become a bottleneck problem restricting the sustainable development of mining areas. [0003] At present, during the mining process of open-pit coal mines, through geological exploration and stripping process, the groundwater becomes mine water. Except for a small part that is treated and used as production and domestic water in the mining area, mos...

The development of open-pit coal mines has affected the original groundwater operation system, making the already fragile ecological environment worse, and the protection and utilization of water resources has become a bottleneck problem restricting the sustainable development of mining areas

[0003] At present, during the mining process of open-pit coal mines, through geological exploration and stripping process, the groundwater becomes mine water. Except for a small part that is treated and used as production and domestic water in the mining area, most of it is discharged after simple purification treatment, forming a huge On the one hand, it occupies land, on the other hand, due to the large evaporation of surface water, a large amount of water resources are evaporated, resulting in huge waste, and it is difficult to realize the effective use of water resources
