Abstract
Description
Technical Field
[0001] This utility model relates to a drainage device, specifically a drainage device for water control in coal mining. Background Technology
[0002] Coal mines are areas rich in coal resources that are mined. They are generally divided into underground coal mines and open-pit coal mines. During the mining process, a large amount of groundwater seeps out. When mining underground, it is necessary to continuously discharge the seeping groundwater. Therefore, drainage equipment needs to be installed in underground coal mines to discharge the groundwater.
[0003] Existing drainage equipment used for water control in coal mines often contains large amounts of silt and sand in the accumulated water. This silt and sand can clog the inlet of the drainage device, preventing effective drainage and, in severe cases, damaging the drainage pump. In some coal mines, the water level is too low to allow the pumping hood to be lowered into the water, making pumping impossible. Furthermore, the drainage equipment directly discharges the pumped-out muddy water, causing silt and sand accumulation, and wastewater flowing into rivers, severely damaging the environment. The silt and sand clogging the drainage device can also damage the equipment itself. Therefore, those skilled in the art have proposed a drainage device for water control in coal mines to address the problems mentioned above. Utility Model Content
