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.
Wireless Communication in Underground Mines focuses on the recent advancement in wireless communication technologies for underground mines and other hazardous areas. This comprehensive book provides a unified foundation of wireless communication systems for transmission of data, voice and video. The book also incorporates intrinsically safe design and development aspects of circuits, which are essential for underground mines and hazardous areas. The book consists of recent wireless communication technologies designed and developed by the authors for underground mines and draws upon their experiences in the fields. Wireless Communication in Underground Mines covers a wide range of the recent practices of wireless communication systems as well as wireless sensor networking, radio frequency identification devices, system specific embedded software, application software, and designing and developing techniques for intrinsic safe circuits.

Wireless communication has emerged as an independent discipline in the past decades. Everything from cellular voice telephony to wireless data transmission using wireless sensor networks has profoundly impacted the safety, production, and productivity of industries and our lifestyle as well. After a decade of exponential growth, the wireless industry is one of the largest industries in the world. Therefore, it would be an injustice if the wireless communication is not explored for mining industry. Underground mines, which are characterized by their tough working conditions and hazardous environments, require fool-proof mine-wide communication systems for smooth functioning of mine workings and ensuring better safety. Proper and re- able communication systems not only save the machine breakdown time but also help in immediate passing of messages from the vicinity of underground working area to the surface for day-to-day normal mining operations as well as for speedy rescue operations in case of disaster. Therefore, a reliable and effective commu- cation system is an essential requisite for safe working, and maintaining requisite production and productivity of underground mines. Most of the existing systems generally available in underground mines are based on line (wired) communication principle, hence these are unable to withstand in the disaster conditions and dif?cult to deploy in inaccessible places. Therefore, wireless communication is an indispe- able, reliable, and convenient system and essential in case of day-to-day normal duty or disaster situations.
