This utility model relates to a self-leveling positioning marker for mining, belonging to the field of positioning marker technology. The utility model includes a pipe clamp, a universal joint, a plumb bob, a marker, a U-shaped connector, a marker base plate, and a connecting assembly. The pipe clamp connects the overhead pipe and the U-shaped connector; the upper end of the universal joint connects to the U-shaped connector; the connecting assembly connects the lower end of the universal joint and the marker base plate; the plumb bob connects to the connecting assembly; and the marker is fixed to the marker base plate. This utility model enables the marker base plate to automatically adjust to a horizontal state, ensuring the marker plane is parallel to the ground, providing a stable visual positioning reference for inspection robots, effectively improving positioning accuracy. It is suitable for auxiliary positioning in complex environments such as mine roadways, ensuring that inspection robots obtain a stable and distortion-free positioning reference during vertical scanning, thereby improving auxiliary positioning accuracy and environmental adaptability.
