Wireless communication is very valuable in underground mines, in which channel characterization plays an important role. In this paper, both narrowband and wideband measurements at three typical ultra-high frequencies of 433, 900 and 2400 MHz in a real mine shaft are performed. To our knowledge, this is the first work focusing on radio propagation in the mine shaft environment. Important channel characteristics, such as the path loss, delay spread and the number of multipath components were extracted from the measured data and compared with that in tunnel channels. The effects of frequency and antenna position on the path loss were investigated. The relationship between the root-mean-square (RMS) delay spread and the transmitter-receiver distance was also analyzed. The results will deepen our understanding of the mine shaft channel and help to design shaft wireless systems.
