PROBLEM TO BE SOLVED: To provide a radio communication system and a mine management server that prevent reduction in the operation rate of a mine due to radio disruption.SOLUTION: Each of a mine management server 31 for managing the operation state of a work machine 20 operating in a mine and a terminal device 26 comprises a communication control unit 261b for controlling multiplexed radio communication connection using a broadband communication line and a narrowband communication line having a narrower band than the broadband communication line. Regarding first type data for shifting the work machine 20 to next operation of data transmitted and received by radio, the communication control unit 261b outputs transmission object data to both of a first system radio communication device 121 for connecting with the broadband communication line and a second system radio communication device 122 for connecting with the narrowband communication line (S806/Yes, S807 and S808). Second type data that is used for operation of the mine but does not shift the work machine 20 to next operation is output to the first system radio communication device 121 every time, but to the second system radio communication device 122 less frequently than output to the first system radio communication device 121 (S806/No and S808).SELECTED DRAWING: Figure 8

    【課題】無線途絶による鉱山の稼働率の低下を抑制する無線通信システム及び鉱山管理サーバを提供する。【解決手段】鉱山内で稼働する作業機械20の稼働状態を管理する鉱山管理サーバ31及び端末装置26の其々は、広帯域通信回線及びそれよりも帯域が狭い狭帯域通信回線を用いた多重化無線通信接続の制御を行う通信制御部261bを備える。通信制御部261bは、無線送受信されるデータのうち、作業機械20を次の動作に移行させるための第1種データは、広帯域通信回線に接続するための1系無線通信装置121及び狭帯域通信回線に接続するための2系無線通信装置122の双方に送信対象データを出力する(S806/Yes,S807,S808)。鉱山の操業のために用いられるが作業機械20を次の動作に移行させない第2種データは、1系無線通信装置121には毎回出力し、2系無線通信装置122には1系無線通信装置121に出力する頻度よりも少ない頻度で出力する(S806/No,S808)。【選択図】 図8
