Wireless Audio/Videoless Communication Between Miners Working Underground and Control Station at Surface

Disasters in coal mines are very common and keep appearing frequently in our country as well as in the other countries in different parts of the world. Analysis on these accidents shows that most of the accidents are related to human factors. It affects the efficiency of the miners and that in turn affects the productivity of the mines. Several technologies are emerging to prevent and mitigate the disasters. The systems based on these technologies employ some software or other, for communicating the occurrence of disaster and persons trapped in it. A large number of communication software are developed and installed in coal mines all over the world. However, in most of the case, the mode of communication between the miners and the control station is either audio or video. These kinds of communications include the personal involvement of the miner as he has to convey his state of health visually/orally to the control station. This involvement not only hampers the working of the miner but also slows down the communication speed as well. In view of this it is proposed to develop data communication system through software and hardware (MineCom), which is going to inform the central control room about the disaster having occurred and its location.
