为了管理现代化的煤矿企业,必须保证传输和处理有关工艺操作的进程、矿井大气状态和矿井设备工作的信息。所有这一切就构成了强大的信息流。目前这些信息是靠电话电缆、动力供电线路、接触线路、专门安设的多芯电缆和同轴电缆传递的。井下通讯线路运行条件的特点使得现行敷设电缆标准的要求不能得到满足。根据这些标准,必须保证动力电缆与电话电缆之间有一定的距离,否则就会造成互相干扰,降低通讯线路的安全性和信息传递的可靠性。
In order to manage modern coal mines, it is essential to ensure the transmission and processing of information on the progress of the process operations, the state of the mine’s atmosphere and the operation of the mine equipment. All of this constitutes a powerful flow of information. Currently, this information is delivered via telephone cables, power supply lines, contact lines, specially installed multi-core cables and coaxial cables. Downhole communication lines operating conditions make the current requirements of the laying of cable standards can not be met. According to these standards, there must be a certain distance between the power cable and the telephone cable, otherwise it will cause interference with each other, reducing the safety of communication lines and the reliability of information transmission.
