Yangmei group built the first 5G base station of underground coal mine in China

Recently, Shanxi Mobile, together with Yangmei group and Huawei Company, successfully deployed the first batch of 5G base stations of coal mines in Yangmei group Xinyuan Coal Co., Ltd. in China and carried out networking application, realizing 5g coverage of main mine roadway and transportation roadway. The underground coal mine has complex working conditions and special scenes. After more than two months of field investigation and in-depth discussion, the three parties have jointly completed the explosion-proof transformation of 5g base station. Shanxi Mobile 5g Lianchuang laboratory independently innovates and develops multi-mode and large gain mine special antenna, coordinates the whole process of field work, successfully completes the new transmission and landing work of base station, and finally overcomes various difficulties such as no GPS of underground base station, large optical attenuation of mining ring network, multiple underground electric and gas equipment concentration, strong multi-path interference of mine, and completes underground 5 in one week On November 18, the 5g base station and the HD video system were successfully connected. After preliminary optimization, the field test data shows that single underground 5g base station can effectively cover the mine area with a length of more than 400m, the downlink rate is stable at more than 800Mbps, the uplink rate is stable at more than 70mbps, the end-to-end delay is less than 20ms, which is beyond the expectation of customers, meets the actual demand rate, is better than the control parameter requirements, and can fully meet the remote ultra-low delay operation Control, Ultra HD video simultaneous interpreting and industrial control scenario for network demand. This is the first time to realize the deployment and application of 5g in the coal mine underground operation scene in China, marking the key step of 5g intelligent mine. In the next step, Shanxi Mobile will continue to rely on "5g joint innovation mechanism", cooperate with Yangmei group, Huawei and other partners to develop "5g + Intelligent Mining", "5g + intelligent driving", "5g + auxiliary transportation", "5g + intelligent inspection" and other kinds of "5g +" mine intelligent systems, improve the safety management and control capacity of coal mines, improve the production and operation capacity of coal mines, and promote with "5g +" technology as the traction The construction of intelligent coal mine, continuously promote the coal mining industry in Shanxi and even the whole country to change the coal mining mode, and move forward to the era of green intelligence.
