Mine underground reaches hundreds of meters often, mine water contains a large amount of coal dust and salt, and the mine water is discharged from underground to the ground, so that on one hand, larger electricity consumption is required, and on the other hand, the coal dust and salt are severely worn and corroded on the pipeline. The coal mine is basically located in northern areas, and the winter heating cost of ground treatment facilities is high. Thus, mine water is increasingly being treated downhole. However, the underground roadway is narrow, flammable and explosive substances such as gas, coal dust and the like exist underground, and underground treatment has more difficulty according to the conventional thought of the ground.

Supernatant fluid in the concentrated water circulating pool flows into the raw water tank, and the sediment concentration reaches more than 3 percent and is directly sent to a dehydrator for dehydration, so that the mine water is treated underground.
The underground cross-flow direct filtration system further comprises a gas washing pipeline, and the gas washing pipeline is communicated with the inorganic ultrafiltration membrane.
Through the air washing pipeline, the air washing mode is adopted to increase the scrubbing of the membrane surface and slow down the membrane pollution.
