Description

Technical Field

[0001] The utility model relates to the field of coal mine sampling, in particular to a geological structure detection device used in coal mine working face recovery. Background Art

[0002] Coal mining areas are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine.
