Description

Technical Field

[0001] The invention relates to the technical field of mining production, and in particular to a rapid mud discharge device for an underground mining water tank and an application method thereof. Background Art

[0002] During the mining process, after the underground water passes through the mining face and the transportation tunnel, it contains a large amount of mud and sand. Together with the particulate matter in the filling water, when it enters the water tank, it will precipitate and produce a large amount of mud and sand, which not only reduces the water storage capacity of the water tank, but also seriously affects the service life of the drainage pump. For this reason, mud discharge from the underground water tank is a very important link. The existing mud discharge method usually uses a special mud pump to discharge water and mud together, but the sewage and sludge in the sewage will still remain in the water tank. The current cleaning method generally treats the sludge remaining in the water tank and the sewage pipe separately. This method not only has a slow sludge treatment efficiency, but also affects the discharge of sewage. It is extremely inconvenient to use, and has a great impact on the treatment of sewage in the mine water tank and the overall efficiency of mining production. Summary of the invention
