The ecological irrigation system obtained in the above steps is shown in fig. 2 and 3, and utilizes mine water of a coal mine underground reservoir to irrigate farmland in a mining area. As shown in fig. 1, a groundwater channel 1 is arranged at an optimal mine water taking position of an underground reservoir, and the groundwater channel 1 extends downwards from the ground surface to below a groundwater level; a water lifting device 4 and a main irrigation pipeline 9 are arranged in the underground water channel 1; the output end of the water lifting device 4 is communicated with the irrigation main pipeline 9 and is used for conveying the water in the underground water channel 1 to the irrigation main pipeline 9. Wherein, the main irrigation pipeline 9 comprises a lifting section positioned in the underground water channel 1 and an irrigation section positioned in a soil layer below the frozen soil layer. The pipelines are realized by adopting the pipelines conventionally selected in the existing reservoir.
In the above scheme, the mine water is lifted to the irrigation section of the main irrigation pipeline 9 through the water lifting device 4, so that the surface land is irrigated, and meanwhile, the frozen pipe phenomenon cannot occur in winter because the irrigation section is located in the soil layer on the lower side of the frozen soil layer. The water lifting device 4 can be realized by adopting a water pump, the water pump is controlled by a control system to be opened or closed, and when the mine water is required to be lifted from the underground water channel 1 to the irrigation main pipeline 9, the water pump can be opened to provide lifting force for the mine water.
