Abstract: In order to solve many problems such as a wide variety of equipment and different equipment operating systems and data protocols caused by different equipment manufacturers in the process of intelligent construction of thin coal seam comprehensive mining face, taking the 12422 comprehensive mining face of Ulanmulun Coal Mine as an example, the characteristics and equipment layout of the comprehensive mining face of thin coal seam were analyzed, and combined with the relevant guidance requirements for the intelligent development of coal mines, an underground 5G communication network was established, the operating system of Kuang Hong was transplanted into the equipment of the comprehensive mining face of thin coal seam. The results show that the system unifies the data interface and data protocol standards between the equipment, realizes the interconnection between the equipment and the intercommunication of information, and the successful application of the Kuang Hong operating system in the comprehensive mining face of the 12422 thin coal seam not only improves the mining rate of the thin coal seam, but also enables operators to control the equipment through the intelligent explosion-proof mobile phone.
