A drainage pipe 19 is installed at one end of the purification box 3 to facilitate the discharge of purified water for daily use, and the other end is connected to the water storage channel. 1 is connected through the extraction component, and for the purification box 3, a treatment membrane 10 (which can be a hollow fiber ultrafiltration membrane or an RO membrane, and the figure does not show the style of the treatment membrane 10, but only represents that it is the treatment membrane 10, which is a relatively mature technology and will not be described here), an activated carbon plate 21 and a filter screen 20 are arranged inside the purification box 3 along the direction from the drain pipe 19 to the extraction component. According to the actual situation of the coal mine, corresponding flocculation sedimentation, aeration and other treatment devices can also be arranged when purifying groundwater. They are arranged according to the actual situation, which is a relatively mature technology and will not be described here.

[0026] See also Figure 1-Figure 5In order to facilitate the utilization of coal gangue in the coal mining area, groundwater can be preliminarily purified and filtered through it, and it is convenient to replace it. A holding bucket 8 for holding components is arranged inside the water storage channel 1, and leakage holes 13 are equidistantly provided at the bottom of the interior thereof to facilitate water to enter the holding bucket 8, and the interior thereof is filled with coal gangue (the particle size gradually decreases from bottom to top, and gauze can be provided on the topmost layer to prevent coal gangue from entering the water storage channel 1 and ensure the filtering effect.
