The water penetration accident is also called as water bursting accident, and refers to a flood accident, which is commonly called water penetration, caused by that surface water and underground water flow into a mine working surface through various channels such as cracks, faults, collapse areas and the like without control because water prevention measures are not in place in the construction and production processes of a mine. Coal mine water permeability and gas explosion casualties are large, and serious accidents, even extra-large accidents are often caused. Therefore, in the emergency of water-permeable accidents, the underground space and oxygen are limited and continuously reduced, and the water must be discharged in a short time, so as to fight for underground personnel for rescue.
The existing mine underground drainage pipeline is an important task for draining underground water burst and production wastewater of a mine and draining and rescuing accidents, and is a key link for ensuring the safe production of the mine. Because the existing drainage pipelines are mostly designed in a high-low drainage mode, the existing drainage pipelines are not suitable for mine drainage from bottom to top. In the water pumping and rescue process, because solid components such as coal blocks and stones are mixed in the accumulated water, the conventional pipeline often falls back or piles up due to the solids, so that the fluid passing rate is reduced, the normal drainage of the pipeline is hindered, and the rescue time is prolonged.
