Abstract: According to the current situation of wireless communication system of Wangpo Mine, the KT130 type mine wireless communication system was imported, the network technology and the network structure which used in the system was introduced, the composition of the system was expounded, the base station signal distribution was designed both the ground and underground in accordance with the actual production requirements, all the underground mining roadway was completely covered with wireless signal basically. The stability of system operation was improved because the signal transmission using the mine industrial Ethernet ring network. Application results showed that the KT130 type mine wireless communication system could replace the original PHS in the use function. The application of the KT130 type mine wireless communication system provides a communication guarantee for safety production throughout Wangpo Mine.
