[0002] Of my country's 14 coal energy bases, 7 are located in arid and semi-arid regions. Coal mining has caused a certain degree of ecological damage, and the protection and utilization of water resources are particularly important in the process of ecological restoration.

[0003] Most of the Loess Gully Region is located in arid and semi-arid areas. Its characteristics include concentrated rainfall in July and August, which has problems such as large soil erosion and high soil evaporation. In addition, the water resources in the Loess Gully Region are unevenly distributed in time and space, with more rain in summer and less in spring, autumn and winter; more rain in the valleys and less in the top and middle of the slopes.

[0004] In the first prior art, a method for utilizing natural precipitation suitable for mine spoil heaps and mine pits is provided, but it requires the construction of maintenance roads and the excavation of large-scale containment trenches and intercepting ditches. It can play a certain role in open-pit mine spoil heaps with limited land area, but it is not suitable for underground mines in the loess gully area of ​​the middle reaches of the Yellow River with complex terrain and large land area.

[0005] In the second prior art, an intelligent water supply and storage device is provided, but it is only applicable to places such as residences and communities, and relies on the water level to regulate water supply and storage, rather than being able to actively regulate based on external needs (e.g., adjusting water supply according to the dryness and wetness of the soil).

[0031] Please refer to Figure 1 The present invention provides a method for forming a water storage area, comprising: surveying the surface of a mining area to obtain a subsidence-stabilized zone to be operated on the surface of the mining area, and selecting a crack of a predetermined size from a plurality of cracks in the subsidence-stabilized zone as an operational crack; grouting the bottom of the operational crack with concrete, so that after the concrete solidifies, a supporting bottom wall 100 is formed at the bottom of the operational crack, and the crack space above the supporting bottom wall 100 is a water storage area 10, so as to use the water in the water storage area 10 to irrigate the soil around the operational crack to be irrigated.

[0032] This invention selects a crack of a predetermined size from multiple cracks in a subsidence-stabilized zone to be operated in a mining area as the operating crack. The bottom of the operating crack is then grouted with concrete. After the concrete solidifies, a supporting base wall 100 is formed at the bottom of the operating crack. The crack space above the supporting base wall 100 serves as a water storage area 10. This method of forming the water storage area eliminates the need for constructing maintenance roads or excavating large areas of containment trenches or intercepting ditches. This makes the water storage area suitable for loess gully areas with complex terrain and large land areas. Furthermore, the water in the water storage area 10 is used to irrigate the surrounding soil to be irrigated, thus solving the problem of uneven spatial and temporal distribution of water resources in loess gully areas in existing technologies.

[0033] In this context, along the depth direction of the operating crack, the bottom of the operating crack refers to the end of the operating crack that is furthest from the ground.

In this way, water-guiding slopes are provided on both sides of the water inlet 110, which can improve water storage efficiency.
