Technical Field

[0001] This utility model belongs to the technical field related to mine drainage equipment. More specifically, it particularly relates to a drainage device for coal mine geological exploration. Background Art

[0002] In actual mining, the underground operation environment is complex, and there may be groundwater and surface water around. At this time, we usually need to drain water in time. If the water is not drained in time, the underground of the mine will gradually accumulate water, and the rising water level may flood the operation area, roadway and equipment, affecting the work progress and also endangering the operation personnel.

[0003] In the actual mining drainage operation, the drainage equipment will be blocked by bottom sludge, garbage and lumps, causing machine failures. When the drainage equipment fails, the accumulated water in the mine cannot be drained in time, which may force the mine to stop production. This will not only affect the production progress but also cause economic losses.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a drainage device for coal mine geological exploration is provided, in order to achieve a more practical value purpose. Content of the Utility Model
