▲ Xinyan Coal Mine relies on 5G communication technology to promote intelligent transformation and achieve unmanned and intelligent operation in hazardous production areas. Wei Liang enjoyed video calls while taking photos on towering mountains, experiencing 5G surfing in humid underground areas, and experiencing "cloud based" farming in smart greenhouses... From mountains to mines, from cities to rural areas, from education to medical care, and from fields to dining tables, 5G signals are crossing mountains and mountains, bringing vitality to the "intelligence" of the revolutionary base area of Shanxi Lvliang. Lüliang Mountains stands like a bone ridge with towering peaks. In the depths of the cloud forest, only laughter can be heard but no one can be seen. The construction of 5G network is particularly important. ▲ Xinyan Coal Mine, coal miners step out of the intelligent comprehensive mining face underground centralized control center. Wei Liang said, "Up to now, Lvliang Mobile has invested a total of 1253.6 million yuan in 5G construction, built more than 3100 5G base stations, and made 5G networks from county to county, township to mining, and industry to industry." On the 10th, the person in charge of Lvliang Branch of Shanxi Mobile said that at present, there are 1260 gigabit communities in the districts and counties of Lüliang City, with a comprehensive coverage rate of 98.76%. With the help of a smooth network, the e-commerce live streaming of "one village, one internet celebrity" in Xingxian is in full swing. Baoma, who is unemployed and at home, has transformed into a "live streamer", and villagers share the beauty of rural cuisine on short video platforms; The bowl troupe in Liulin County, the folk tunes in Linxian County, the pastoral style of North Wudang in Fangshan County, and the red culture of Liu Hulan Town in Wenshui County are entering the hearts of thousands of netizens through the small screen. 5G empowers coal mines and also gives black gold wings of "cloud". In Xinyan Coal Mine in Zhongyang County and Zhaiyadi Coal Mine in Liulin County, "5G+Smart Mining" has realized the management of "one network" above and below the shaft, and the traditional manual coal mining has moved towards unmanned and intelligent coal mining; In Xiaoyi Dongyi Group, the "5G+intelligent patrol" made workers say goodbye to the "dirty, tired and dangerous". The machine patrol inspector turned into a personal assistant to patrol the belt conveyor "man, machine and ring" all day long, realizing "manned patrol and unmanned operation". There are combustible gases such as coal dust, methane, and ethane underground in coal mines. Ordinary communication equipment is prone to generating electric sparks during use, leading to underground explosions or fire accidents, posing significant safety hazards. In response to this practical problem, Shanxi Mobile Lvliang Branch has developed an intelligent coal mine solution for Xinyan Coal Mine. Through the application of "Zhikuangtong", we can obtain real-time communication on the ground and underground, and support high-definition video calls. "Even if we are deep in the mine, operators can keep in touch with the ground control center through mobile terminals at any time and anywhere, and the workers on the ground can flexibly allocate the call permissions of operators according to their job responsibilities and task requirements, which solves the" hoops "of communication safety for underground personnel." There are many mountains in Lvliang, and the terrain is complex, Underground tunnel wiring is difficult, costly, and has weak network coverage. We drill back and forth in dozens of kilometers of tunnels every day. The mine is dark and humid, with tight schedules and heavy tasks. We only want the project to be delivered on schedule, and the workers can quickly use intelligent terminals. "Member of the network construction team of Shanxi Mobile Lvliang Branch
