Intelligent mine platform is able to increase mining production

among which communication

positioning and sensing system can guarantee miner and mineral safe. However

the lack of bandwidth of traditional redio frequency signal

serious attenuation and heavy communication equipment limit its application in mine. 5 G signals can be applied in mines

but electromagnetic interference is still existed. The wireless optical signal has the advantages of immune electromagnetic interference and high bandwidth

and the wireless optical communication

positioning and sensing can rely on the underground light source facilities

which reduce the cost and loss of communication equipment. This paper introduces the research status of mine wireless light from the aspects of wireless light propagation characteristics

wireless light communication scheme

wireless light positioning and wireless light sensing. Finally

we forecast the development of mine wireless light communication district layout

light source design

relay scheme and mine car collision prevention.
