In response to the problems of high cost and low reuse rate of wired networks, small coverage range and high interference of wireless networks, the in-depth research was conducted on the existing network system in uranium mines, and demand analysis was carried out based on the actual needs. With the goal of full coverage of wireless local area networks for signal wireless transmission, positioning, and remote monitoring of underground personnel and equipment, and on the basis of unified network transmission protocol, the applicability of wireless network transmission technologies such as 5G and Wi-Fi was analyzed. Suitable equipment and working frequency bands were selected, and a network testing platform was built for wireless signal transmission rate and delay experiments to verify the applicability of underground wireless technology applications. The result can guide the construction of underground networks in uranium mines and provide reliable network support for underground production equipment monitoring, environmental monitoring, positioning, communication and important data transmission.
