SYSTEM OF RADIO VOICE CONNECTIONS USING IN MINE ZD RMU KAKANJ D.O.O. KAKANJ

Summary/Abstract: Beside exploitation of mineral resources, saving people, animals, materiality goods and environmental protection are also part of mine industry. Radio connection or radio links presents the solution for flexible and effective communication among people for many years. Systems of radio-links present the second largest group of professional telecommunications. The space between input and output is called free space. Radio connection systems in mines are mostly presented through: radio-telegraphy, radiotelephony, radio mechanics, radio location and internal television. For the needs of automation and necessary work in mines, and because of its regularity and safety, the usage of radio-links is an indispensable need. Without using a radio devices it is not even unthinkable connection between dispatcher center and work machines; maintaining connections with teams responsible for troubleshooting on machines and devices, plants, telecommunication and signal-safety devices and cables. Radio connection enables current communication between one or more participants by simple clicking on button. System radio-telephone link for the needs of Mine Kakanj, primarily serves for transfer and exchange voice messages among participants in this system, whom can also be mobile during communication, so with this technical characteristic it makes the system of mobile terrestrial radio links. Participants of this system are employees of this company. Operatively, the importance of timing in giving services and synchronization participants, form a set of elements necessary for successful and rational management, and also to secure radio-telephone system. Radio-telephone system will be consisted from Repeater stations located on mountain Vrana, which will also have function of controlling stations for whole system, manual and transceiver stations. Work describes the usage of systems and devices used for radio-voice links that will be consisted in Mine ZD RMU Kakanj. The goal of this work is to present how information technologies though systems of radio links can develop safety in Mines of their employees and materially technical goods.
