This invention keeps the wireless communication quality at each point inside a mine more up to date without changing the operating states of hauling vehicles. This wireless system for use in a mine is provided with the following inside said mine: a server 31, wireless relay stations 41, and dump trucks 20. The server 31 contains operation-management information and communication-quality information, and each dump truck 20 is provided with a GPS and a wireless terminal. The server 31 identifies a target update point for which the communication-quality information needs to be updated. The server 31 then uses the operation-management information to identify a dump truck 20 that is scheduled to transit the target update point, calculates the point in time at which said dump truck 20 will reach the target update point, and performs a communication-trigger process for making the dump truck 20 transmit wireless data at said point in time.
