Abstract: The realization of unmanned, intelligent and wisdom gas management in large coal mines is the development trend of mine production technology, and it is also the national energy strategy decision and deployment requirement. Traditional coal mine gas inspection management methods have many drawbacks, such as false inspections, missed inspections, difficult storage of paper materials, and poor rescue. Coal mining enterprises need to use technology to upgrade management. The major advantages of 5G network technology such as data transmission rate and network capacity are seamlessly connected with the requirements of large-scale coal mine gas management to achieve unmanned and intelligent. Discussed the future large-scale coal mine gas management will go through the three development stages of 5G + artificial + sensor, 5G + robot, 5G + Internet of things, and intelligent interaction. The intelligent terminal at the 5G+manual+sensor stage can accurately locate the roadway and intelligently detect various parameters according to the requirements of the scene. The bionic robot developed in the 5G+robot stage will enable traditional tile inspectors, wind detectors, dust detectors, and monitoring workers waiting for the “one ventilation and three prevention” workers to withdraw from the historical stage of coal mine safety production. In the 5G+ IoT and intelligent interaction stage, everything is a gas management participant. The mine’s “smart brain” will use virtual reality and other technical means to deal with gas abnormalities and take measures to finally realize the intelligent management of mine gas.
