摘　　要：为了确保5G技术在矿井的安全使用,促进煤矿移动通信的快速发展,探讨了矿井移动通信系统应用现状,研究了爆炸性环境的相关标准,分析了阈功率的计算方法,讨论了考虑天线叠加情况下与不考虑天线叠加情况下基站发射阈功率的计算过程,分析了电磁兼容评价标准和矿用5G系统安全性评估方法;并在发射阈功率参数、电磁兼容、核心网检验、系统组网方式判别、通信类别及制式检验、天线参数检验等方面提出了矿用5G产品安全性能的计算和测试方法,规范了矿用5G产品生产,保障了井下人员、资源设备安全。In order to ensure the safe use of 5G technology in mines, and to promote the rapid development of mobile communication in coal mines, the application status of mobile communication system in mines was discussed. The relevant standards of explosive environment were studied, the calculation method of threshold power was analyzed, and the calculation process of base station transmitting threshold power with and without antenna stacking is discussed separately. The electromagnetic compatibility evaluation standard and the safety evaluation method of mining 5G system are analyzed. The calculation and testing methods for the safety performance of mining 5G products are proposed in terms of transmission threshold power parameters,electromagnetic compatibility, core network inspection, system networking mode discrimination, communication category, system inspection, antenna parameter inspection, etc. These standardize the production of 5G products for mining and ensure the safety of underground personnel and resource equipment.
