They are effective and simple to use for detecting underground infrastructure as long as it is accessible and conductive (so as to be able to induce a signal in the pipe or cable). The Leica DS2000 GPR devices (for example, the Leica DS2000 ) can detect not only nonmetallic objects, but also provide 3D location (reporting depth as well as X,Y ...

Establishment of a reliable system in an underground mining environment is very difficult because of extreme working conditions [8] [9] [10][11]; poor line .
Radio signal mapping. Research has shown that radio frequency (RF) signal propagation in underground mines differs significantly from that on the surface (Emslie, Lagace and Strong, 1975; Zhou et al., 2015; Jacksha and Zhou, 2016).With this in mind, it was decided to carry out RF signal mapping in areas of the mine where remote data radios could possibly be installed.

The system also enables the banksman to signal to each underground level and also to signal to the winding engineman. In addition to the shaft signaling system for sending out and registering normal working signals, there is usually an emergency stop system which can be operated from any signalling position. When an emergency stop key is ...
The proposed Mining Plan Modification would allow Signal Peak to continue underground coal mining, within the permit area, on approximately 1,725 acres of additional Federal coal lands. In connection with mining this Federal coal, Signal Peak would also mine adjacent private and State coal.

The underground/surface receivers flashed cap lamps and activated remote devices, such as strobe lights, within 30 to 40 s after the encoded signal was received. Evaluation results showed fullmine coverage of the electromagnetic field and that the encoded signal was received at the farthest point underground and on the surface perimeter.
