[0002] Based on the refraction and reflection of light, when light passes through a prism, due to the changes in the light speed and the direction of the light ray when the light passes through different media, the light ray will be decomposed into different spectra, and this phenomenon is called dispersion. In addition, the prism can also change the propagation direction of light through reflection and refraction. Before and during the gold mine mining, underground surveys are required to master the driving direction and driving level. The suspended prism meets the basic control traverse survey work underground, and the accuracy fully meets the relevant regulations of the "Coal Mine Surveying Regulations", and can effectively reduce the labor intensity of surveyors and improve the survey speed. When the existing prism is suspended, it is generally suspended by a hook, which is easily affected by the external environment and shakes, affecting the normal use of the prism.
