Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine water hazard treatment, in particular to a mine water hazard prevention and control device. Background Art

[0002] At present, water disasters in coal mines affect the progress and quality of mine construction, worsen the working environment of workers, increase the drainage facilities and drainage costs of mines, and bring unsafe factors to coal mine production. In severe cases, flooding accidents may even occur, causing significant losses of life and property. In the process of coal mining, it is very easy to cause water accumulation in old cellars, causing mine water seepage accidents. Coal mine water disasters will also lead to erosion and weakening of surrounding rocks, induce secondary disasters, damage water resources, and reduce resource recoverability.

[0003] For example, Chinese utility model patent CN214464382U discloses an improved coal mine comprehensive mining water hazard prevention and control device, which is provided with a sewage outlet at the lower left end of the filter screen fixedly installed in the middle of the sewage pipe, and an L-shaped sewage storage pipe is fixedly connected to the lower end of the sewage outlet. When we extract the accumulated water in the mine, a large amount of impurities in the accumulated water can be filtered out through the filter screen in the sewage pipe, because the impurities will accumulate in the sewage storage pipe at the lower end of the sewage outlet under their own gravity. Finally, the impurities in the sewage storage pipe are regularly cleaned to ensure smooth drainage, which is conducive to more practical use of the improved coal mine comprehensive mining water hazard prevention and control device; because a rubber mounting port is provided in the middle of the mounting plate, and a filter frame is fixedly installed on the outer side of the lower side wall of the mounting plate, when the filter frame is fixed in the middle position of the liquid pump through the locking port, a large amount of impurities can be effectively blocked from entering the drainage pipe during liquid extraction, which is conducive to more practical use of the improved coal mine comprehensive mining water hazard prevention and control device.

[0004] Although the above-mentioned prior art can temporarily filter and store impurities, if there are too many impurities, the machine needs to be stopped to clean the impurities during pumping, which will lead to poor drainage efficiency. Utility Model Content
