Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coal mine water treatment, and in particular relates to a flat pan water drainage device for open-pit coal mines. Background Art
[0002] Open-pit coal mines refer to coal deposited on the surface or shallow coal layers due to geographical changes, which are directly mined through open-pit mining. Open-pit mining can obtain a larger proportion of coal mines than underground mining, because more ore layers are used. Open-pit coal mines can cover an area of tens of square kilometers. About 40% of the world's coal production uses open-pit mining.
[0003] Open-pit coal mining operations have formed a depth reduction funnel, and groundwater is continuously replenished into the open-pit coal mine pit, which has a large erosion capacity. At the same time, after entering the rainy season, as the rainfall increases, there is more water accumulation in the open-pit coal mine flats, which can easily cause flat collapse and road interruption. The destruction of the flats poses a major hidden danger to vehicle traffic and side stability, and will also incur higher flat management and restoration costs. Therefore, effective control of flat water accumulation can avoid groundwater damage to loose rock flats, which has a significant effect on the stability of the side walls of open-pit mines and safe production.
[0004] However, in the process of using the existing flat plate water drainage device, most of them directly discharge the accumulated water and filter the sludge and other materials and then clean them manually, which is not only time-consuming, but also requires frequent cleaning of the filter device due to the large amount of dust and sludge in the coal mining area, which is a waste of manpower; in addition, when discharging the accumulated water on the open-pit coal mine flat plate, the accumulated water and sludge cannot be effectively utilized.
