Description

Technical Field

[0001] The utility model relates to the technical field of anti-leakage of mine closed walls, in particular to a device for preventing water leakage and returning water to a mine closed wall. Background Art

[0002] Mine fireproof and sealed walls refer to walls connected to the goaf and used to eliminate air leakage channels or reduce air leakage pressure differences. Water leakage and backflow may occur during wall installation, so anti-leakage and anti-backflow coordination are required.

[0003] The utility model with the announcement number CN208858404U discloses a device for preventing air leakage and water return in a sealed wall of a mine, comprising a water inlet, a cavity, a water outlet, and a cleaning port. The water inlet and the water outlet are arranged horizontally and symmetrically. The cleaning port opens upward and is arranged above the water inlet. The water inlet, the water outlet, and the cleaning port are connected through the cavity and are higher than the middle of the cavity. The middle of the cavity is horizontal, its bottom surface is placed on the horizontal ground, and a sealed wall is built above it.

[0004] With the above technical solution, the accumulated water in the old pond can flow out freely through the water-repelling device, and the gas flow between the old pond and the tunnel in use can be isolated. It also solves the problem that when the water-repelling device is blocked by the accumulation of silt from the old pond, it can be easily cleaned without affecting the normal use of the water-repelling device. However, the leak-proof water-repelling structure is not convenient for stable combination installation with the closed wall of the mine, and does not have a multi-layer protective structure to reduce the impact of friction damage caused by long-term use.
