Abstract: During the development of intelligent coal mines, coal mines usually build the private clouds and the intelligent integrated management and control platform without the group-level planning, which results in information islands, difficulties in data fusion and data mining. With the utilization of the new generation information technologies such as big data, artificial intelligence, edge computing and cloud computing, a three-level intelligent integrated control platform of the group, regional branch and coal mines was built. The platform included group-level private clouds, regional-branch-level and coal-mine-level data centers, as well as middle ground and application systems. At the group-level, an intelligent group platform with supervision function carried out intelligent analysis and intelligent model training with the massive data mining from production, safety and business operation, so that the platform could provide vital information for the group’s decision making. At the regional-branch-level, an intelligent regional-branch platform with management and operation functions was built, which provided continuous improvement and enhancement feedback to the regional branch, with the support of the group-level platform and statistical analysis of the production, safety and business operation data of subordinate coal mines. At the coal-mine-level, an intelligent coal-mine platform with cooperative management and control functions was built, which connected with the systems of production, safety and business operation, and processed all the safety alarms, faults and potential safety risks in par with the assistance of the group-level and the regional-branch-level platforms.
