Abstract


Modern mines and underground workings , how to implement the underground voice communication , video monitoring , personnel and equipment tracking and positioning to become the first to face the problem of mining enterprise managers . The downhole communication technology is gradually developed in response to these problems , it will be one of China 's mining enterprises upheaval . The establishment of underground communication systems have an important impact not only on the production safety of the underground work , and also has great significance for the achievement of the mining enterprise information and networking . Underground communication systems in a multi-disciplinary study based mining disciplines in the study must not only have knowledge , but also knowledge in the field of computer networks and communication technologies . In the writing of the paper , this article focuses on the following aspects : ( 1) to refer to a large number of references were analyzed on the principle of the underground radio propagation technology , mode of transmission , and anti-fading of the radio transmission technology research; ( 2 ) establishment of underground communication systems using wireless LAN technology . After comparison and analysis of the wired and wireless networks , establishing a the downhole wireless communications network . This article focuses on the working principle of the wireless LAN , using standard protocols , network topology , roaming technology and IP address management allocation ; for wireless LAN security and reliability of the study and the ; ( 3) optical fiber communication technology . Optical fiber communication technology principles and Zuwangfangshi studies , the establishment of a of underground backbone ring network structure . Effective solution to the existing problems in the traditional leaked cable communication by the optical fiber communication technology , wireless LAN , and because of its many advantages to become the development direction of future mine underground communication . The copper mine Dahongshan engineering examples Finally , take full advantage of mature wireless LAN technology and fiber optic communications technology , the establishment of a copper mine underground integrated communications system Dahongshan .
