“…Since RF signal cannot propagate without remarkable attenuation, above the surface technologies; like wireless local area network (WLAN) or wireless personal area network (WPAN) failed to provide desirable result in underground mine. In work [6], authors described different frequencies that may be used in underground mine communication.…”

“…Various mine communication system, namely wired communication systems (coaxial, fiber optics, twisted pair), radio communication system, carrier current communication system and a mix of these two named as hybrid system has been developed over the years. Among these, wired communication is most inappropriate; as mine structure is dynamic and underlying wire get damaged during mining operations and can cause accidents inside the mine [6]. Radio communication system provides wireless connectivity but uses RF band for establishing communication.…”

This paper presents an approach to access real time data from underground mine. Two advance technologies are presented that can improve the adverse environmental effect of underground mine. Visible light communication (VLC) technology is incorporated to estimate the location of miners inside the mine. The distribution of signal to noise ratio (SNR) for VLC system is also studied. In the second part of the paper, long range (LoRa) technology is introduced for transmitting underground information to above the surface control room. This paper also includes details of the LoRa technology, and presents comparison of ranges with existing above the surface technologies.
