[0040] The present embodiment provides a comprehensive treatment system for coal slurry water in underground coal mines, wherein the underground coal mine is provided with mining tunnels, raw coal conveyor belts 6, horizontal tunnels and water tanks 5. The water tanks 5 are used to store coal slurry water. The mining tunnels are tunnels used for coal mining operations; the raw coal conveyor belts 6 are used to convey the mined raw coal; the horizontal tunnels are underground passages excavated in the mine in a horizontal direction or a nearly horizontal direction, mainly used to connect different areas, provide conveying passages, ventilation paths and entrances to the working surface, etc. The mining tunnels, raw coal conveyor belts 6 and horizontal tunnels are parts where coarse particles are easily deposited.

[0041] In this embodiment, the coal mine underground coal slurry water comprehensive treatment system includes a first sedimentation tank 1, a second sedimentation tank 2, a centrifuge 3 and a surface water treatment system 4. Among them, the first sedimentation tank 1 is used to remove large particles in the coal slurry water, the second sedimentation tank 2 is used to remove finer particles in the coal slurry water, and the centrifuge 3 and the surface water treatment system 4 are used to remove fine particles in the coal slurry water. Specifically, multiple first sedimentation tanks 1 are provided, so that the first sedimentation tanks 1 can be configured in the mining tunnel, the raw coal conveyor belt 6 and the horizontal tunnel. The first scraper cleaning machine 11 and the first submersible mud pump 12 are provided in the first sedimentation tank 1. The first scraper bin cleaner 11 has a feed inlet. After the coal slurry water enters the first scraper bin cleaner 11 through the feed inlet, the large particles in the solid phase of the coal slurry water settle in the first scraper bin cleaner 11. The first scraper bin cleaner 11 is provided with a scraper and other structures. The settled large particles are hung to the solid phase outlet by the scraper and discharged to the raw coal conveyor belt 6 through the solid phase outlet; the coal slurry water with large particles removed enters the first sedimentation tank 1 through the overflow port of the first scraper bin cleaner 11, and is transported to the second sedimentation tank 2 through the first submersible mud pump 12 arranged at the rear end of the first scraper bin cleaner 11 in the first sedimentation tank 1.

By arranging the inclined plate settling component 24 in the second scraper cleaning machine 21, the sedimentation of finer particles in the coal slurry water can be promoted.

After testing, it can be achieved that the cleaning frequency of the water tank 5 is extended from once every six months to once every ten years or even more than ten years, which completely solves the problem of cleaning the water tank 5.

[0043] The comprehensive treatment system for coal sludge water in underground coal mines provided in this embodiment pre-treats the coal sludge water by establishing a first sedimentation tank 1 so that coarse particles do not enter the water tank 5, and indirectly clears the water tank 5, thereby reducing the subsequent mine water treatment cost and the wear of subsequent pumps.
