The device is suitable for draining deeply buried underground coal mines and non-coal mine mountains.

As shallow resources are depleted, more and more mines move to the deep. When the deep well is exploited, the problem of disturbance of three heights and one height is faced, and the mine drainage cost is rapidly increased along with the rapid increase of the drainage along with the exploitation depth of the deep well. These all restrict the increase of mining depth and the utilization and recovery of resources of the mine. Therefore, the development of energy-saving cost-reducing mining technology and the reduction of drainage cost are particularly important for deep well mining.

The water is discharged from the mine as soon as possible, so that major safety accidents such as flooding of the mine and the like are avoided, and the mining safety is ensured.
At present, deep well mines face the current situation that a large amount of high potential energy supplied to underground water from the ground surface is not utilized, and a large amount of energy needs to be consumed for discharging the waste water under the deep well, so how to reasonably and economically reduce the high water pressure of the ground surface water supply in the deep well mining and discharge underground water burst, and realizing energy conservation, cost reduction and efficiency improvement is an important problem concerned by the mines. If the high water potential energy in the underground water supply pipeline from the surface of the deep mine can be fully utilized as the power for discharging and lifting the underground wastewater, the utilization of the surface water supply potential energy and the discharge of the underground water can be perfectly combined, the method has wide application prospect in deep mine exploitation, and a new method and a new technology are provided for lifting ore pulp by utilizing the high water pressure at the bottom of the deep well in the deep mine exploitation.
