Description

Technical Field

[0001] The utility model relates to the technical field of geological environment detection, in particular to a coalfield geological environment detection device. Background Art

[0002] Coal is formed from plant remains in geological periods. After the death of plants, their physical and chemical properties are changed by biochemical and geological actions to form coal. This process is called coal formation. Like general sedimentary deposits, coal is always distributed in layers. Any sedimentary rock system with geological causes that contains coal seams is called a coal-bearing rock system. In the process of coal mining, the geological environment is often affected by the conditions of coal seam occurrence, mining methods, and technical levels. This includes collapse of goaf areas, groundwater pollution, dust in mines, soil pollution, etc. In order to better detect the geological environment of coalfields, it is necessary to test the geological environment of coalfields.

[0003] Before mining a coalfield, it is necessary to conduct a geological environment detection on the coalfield. During the measurement process, in order to measure the stratigraphic profile in detail and understand the general situation of the coal seam and the marker layer, a level meter is needed for measurement. However, the surface of the coalfield is not flat, which affects the measurement result. A tripod is required for use, and the level meter needs to be installed. The level meter and the tripod are inconvenient to carry, making it inconvenient to use. Upon retrieval, the patent document with the publication (announcement) number: CN114509053B provides a multifunctional coalfield geological environment detection device, including a placement seat, a sealing cover is provided on the front of the placement seat, a support seat is provided above the placement seat, four connecting rods are rotatably connected to the lower surface of the support seat, and a horizontal surveying instrument is fixedly connected to the upper surface of the support seat. The multifunctional coalfield geological environment detection device, under the action of the lifting component, fixes the height of the support seat to achieve a suitable measuring height to meet the use needs of different personnel. Under the action of the limit component, the support seat can be rotated. When the support seat is rotated to a horizontal angle, the angle of the support seat is fixed.
