Microseismic monitoring is of great significance to mine safety and has been widely used. In view of the problems of large amount of microseismic monitoring data, redundant content, weak real-time display and low integration with mining engineering, a microseismic monitoring data analysis platform based on Unity3D platform was developed. The main process is as follows: 3D geological coordinates of the mine, the lithology of the formation and other datas are collected to build a 3D model of the mine, then they are imported into the Unity3D engine. After that, materials are added to the model, and the model coordinate data with the real coordinate data are rendered and integrated.Based on this,C# language scripting is employed torealize the real-time simulation of mining progress, and then calls the SQL Server data base to call the mine microseismic monitoring data to complete the integration and real-time display of the whole system geological data, mining data and microseismic data. By calling the system data, the relevant statistics and analysis of the microseismic data can be realized, and the correlation with the geological conditions and mining activities can be analyzed. The system has been applied in Yuejin and Changcun mines of Yima coalfield, and the joint analysis of microseismic monitoring data of mine-group mining has been realized.
