Description

Technical Field

[0001] This utility model belongs to the technical field of groundwater collectors, and in particular relates to a groundwater collector for shallow aquifers in coal mining areas. Background Technology

[0002] In areas with frequent coal mining activities, the monitoring and research of shallow aquifer groundwater is crucial. The local groundwater sampler is designed specifically for coal mining areas to accurately and efficiently obtain groundwater samples from shallow aquifers, providing strong support for subsequent water quality analysis, water level dynamic monitoring, and other work.

[0003] During groundwater collection, the groundwater in shallow aquifers may exhibit significant spatial differences in water quality and level. A water sample collected at a single point may not represent the overall situation of shallow aquifers in the entire coal mining area. Furthermore, the flow of groundwater is dynamic. If factors such as flow direction and velocity are not considered during the collection process, the collected water sample may be affected by the mixing of different water bodies in the surrounding area. Therefore, we propose a groundwater collector for shallow aquifers in coal mining areas.

[0004] Therefore, it is necessary to provide a new groundwater collector for shallow aquifers in coal mining areas to solve the above-mentioned technical problems. Utility Model Content
