A wireless system for a mine performs a management of the quality of wireless communication at each point in the mine at a time point closer to a current time while maintaining the operating state of each dump truck. The wireless system is provided with a server 31, wireless base stations 41 and dump trucks 20 in the mine. The server 31 contains fleet operations management information and communication quality information, and the dump trucks 20 each include a GPS and a wireless terminal. The server 31 specifies an update target point where the communication quality information requires an update. Then, the server 31 specifies one of the dump trucks 20, which is plan to travel through the update target point, from the fleet operations management information, calculates a time at which the dump truck 20 would arrive at the update target point, and performs communication trigger processing to make the dump truck 20 transmit wireless data.
