Technical Field

[0001] The utility model relates to the technical field of pumping test devices, in particular to a stratified pumping test device for a water-bearing layer on a roof of a mining area. Background Art

[0002] During the exploration of salt lake minerals, when there are multiple brine-containing mineral layers in the local stratum, in order to understand the water quantity and water quality of each aquifer, it is necessary to conduct pumping tests and sampling work separately. In the past, due to the difficulty of stopping water, pumping tests were often conducted by constructing a borehole for each aquifer, thereby realizing stratified pumping tests on the roof aquifers in the mining area.

[0003] However, during use, when the main control box is removed for equipment inspection and cleaning, the bolts connecting the support frame and the main control box are difficult to quickly locate during assembly. This affects the efficiency of the equipment's inspection, cleaning, and installation after the main control box is removed, and also affects the subsequent stratified pumping test of the mine roof aquifer. Therefore, those skilled in the art have provided a stratified pumping test device for the mine roof aquifer to address the problems raised in the above-mentioned background technology.
