Wireless Communication in Underground Mines

Underground mines require fool-proof, mine-wide communication systems for smooth functioning of mine production and worker safety. Proper and reliable communication systems not only decrease machine break down time, but more importantly provide immediate transmission of messages from the underground working area to the surface for normal mining operations as well as necessary rescue operations in case of disaster. Therefore, a reliable and effective communication system is an essential requisite for safe working, and maintaining the requisite production and productivity of underground mines. Existing wired communication systems cannot reach parts of complex mines, and are ineffective in many disaster situations.
