Background
The water sump is one of the necessary facilities in the coal mine, and before the coming of the rainy season every year, the coal slime in the water sump must be dredged to ensure the production safety in the underground in the flood season. For a long time, domestic coal mines basically adopt manual or semi-manual cleaning to clean underground water bins, and manual cleaning has the advantages of more labor, long time consumption, high labor intensity and poor safety production, and seriously influences the high-yield and high-efficiency construction of mines and the standardized construction of mines.
The domestic mechanical dredging sump mainly comprises the following modes: 1. the machine is simulated to be a tunneling machine type dredging machine, coal slime is collected on a scraping trigger by using a mechanical crab claw, the coal slime is conveyed to a mine car at the back through the scraping trigger, and then the mine car filled with the coal slime is pulled to a conveying roadway through a winch. The method has the advantages that the effect of treating the coal slime with large particles and low water content in the front section can be achieved, but the coal slime with high water content in the middle and rear parts of the water bin has no method and needs manual cleaning. 2. The slurry is pumped into the waste tunnel by a slurry pump, and is loaded by manpower and conveyed to the ground by a long-time air-drying method. But can only be adopted when the waste roadway is available, and has great limitation. 3. High frequency vibrating screen type mechanical cleaning. The device firstly stirs the coal slime water evenly. And then, conveying the coal slime water to a high-frequency vibrating screen by using a special pump for dredging the coal slime, separating the coal slime from water by using the high-frequency vibrating screen, directly spitting the coal slime onto a mine car or a belt conveyor, and returning the screened water to another water sump. Because of the limitation of screen dehydration, when the number of the screen meshes is particularly large, the screen pasting is easy to cause, and the slime water flows out from the screen; when the screen mesh number is reduced, the undersize is increased in a large proportion, so that the speed of the other water sump is increased. The method is suitable for the coal slime with good dehydration performance, and is suitable for the situation that more than 0.2 percent of particles account for more than 60 percent.
