Coal mine underground reservoir monitoring simulation test device

Abstract

The invention discloses a coal mine underground reservoir monitoring simulation test device, and belongs to the field of coal mine simulation test devices. Comprising a test bed, and a bottom plate rock stratum, a coal seam, a spacing rock stratum, a water-resisting layer, a water-bearing layer and a surface soil layer which are sequentially paved in the test bed from bottom to top, and the coal seam comprises an open-off cut area and a coal mine area; the water injection pipe extends downwards into the aquifer along the surface soil layer and is used for injecting water into the aquifer, and a first water quality monitoring device is arranged in the water injection pipe; the first monitoring water pipe is installed in the coal mine area of the coal seam and used for collecting water flowing through the water-bearing layer, the water-resisting layer, the interval rock stratum and the coal mine area of the coal seam, and a second water quality monitoring device is arranged in the first monitoring water pipe; the second monitoring water pipe is communicated with the open-off cut area of the coal seam and used for collecting water flowing through the water-containing layer, the water-resisting layer, the interval rock stratum, the coal mine area of the coal seam and the open-off cut area, and a third water quality monitoring device is arranged in the second monitoring water pipe. The problem that the water quality of mine water cannot be intelligently monitored in an existing coal mine underground reservoir monitoring simulation test is solved.

Description

technical field [0001] The invention relates to the field of coal mine simulation test devices, in particular to a coal mine underground reservoir monitoring simulation test device. Background technique [0002] Coal mine underground reservoir is an important water resource for coal mining. During the operation of coal mine underground reservoir, mine water migrates in the rock cracks and pores inside the underground reservoir, and the suspended matter contained in it is under the action of free settlement and rock mass resistance. The ions and organic matter can be reduced through the water-rock coupling with the goaf rock mass. Therefore, the coal mine underground reservoir can remove the suspended solids, ions and organic matter in the mine water, and then purify the mine water. [0003] Because the coal mine underground reservoir is an underground project, coupled with the complexity and unpredictability of the collapse of the overlying strata above the goaf, similar sim...
