在过去几年中,进行了大量的井下无线电通讯方面的研究工作。然而,直到最近用中频无线电波通过地下金属构件传播进行通讯之前,没有几个系统获得真正的成功。基尔克矿(Quirke)为了提高生产能力和改善安全状况,应用了这项技术。无线电通汛系统的研究分为4个阶段:选择设备;安装试验;扩大到整个试用的无轨水平;扩大到所有无轨水平。选择设备在考虑采用市场提供的9种
In the past few years, there has been a great deal of research on downhole radiocommunications. However, few systems did not achieve real success until recently, using IF radio waves to propagate through underground metal structures. Quirke applied this technology to increase productivity and improve safety. The study of the radio flood control system was divided into four phases: the selection of equipment; the installation of tests; the extension of the trackless level of the entire trial; the extension to all trackless levels. Select the device to consider using the market to provide 9 kinds
