摘　　要：5G在水泥矿山领域的应用发展受到关注。水泥工厂通常依石灰石矿山而建,通过5G网络可满足无人机安全巡检、矿山3D建模、矿车无人驾驶/远程控制等移动业务需求。首先,分析了5G在水泥行业矿山的主要业务场景及网络需求。其次,通过对5G水泥矿山网络部署的实际案例及测试数据分析,矿山5G网络覆盖的难点在于山坡状梯田式开采的石灰石矿山由于山体屏蔽及遮挡作用,5G网络覆盖率和信号强度欠佳。最后,从网络配套、规划仿真以及环境动态变化几个方面总结了5G矿山网络覆盖的难点并给出了初步建议。The application and development of 5G in the field of cement mining has drawn attention.Cement factories,usually built around limestone mines,in which 5G network shows great value to be used for safe inspection by drones,UAV 3D modeling of mines,unmanned driving and remote control of mining vehicles,of excavators and other mobile services.Firstly,the main business scenarios and network requirements of 5G in cement industry mines was analyzed.Secondly,via the analysis of practical cases and test data of 5G cement mine network deployment,the difficulty of 5G network coverage in mines lies in the poor coverage rate and signal strength of 5G network in limestone mines,which are due to mountain shielding effect mined by hillside terraced fields.Finally,the difficulties of 5G mine network coverage were summarized from the aspects of supporting facilities,planning simulation and environmental dynamic change,and preliminary suggestions were given correspondingly.
