Abstract: In order to reduce the occurrence of ecological geological environment disasters caused by mining surface subsidence effectively, Huangyuchuan coal mine has developed a Tianyan-patrol monitoring system for surface subsidence area with traditional surface movement observation station combined with GNSS, UAV, remote sensing, radar and modern sensor technology. The system designs five core functions according to different research objectives and data acquisition ways. The software architecture adopts the modern design concept of front and rear end isolation to separate the data acquisition end, data service end and client end. The data acquisition end transmits the data to the server through GPRS / 4G / 5G technology for data storage and management. Data storage management and application programs are deployed on the server side to realize data management, analysis, mining subsidence calculation and response to client requests. The client realizes data query, modification, and large screen display through HTTPS request of browser. The client and data server design rest API technology to realize the separation of front and back ends. Taking the three functions of surface movement observation station analysis, geological environment risk zoning and mining subsidence prediction of 11401 working face of Huangyuchuan coal mine as examples, the engineering application demonstration is carried out. The deployment and application effect of the system shows that the system realizes the integration and unification of data acquisition, data management and data use. It provides a basic basis for data analysis and decision-making in the direction of ecological geological environment monitoring to promote the construction of intelligent green mine in Huangyuchuan coal mine. The system research results have popularization and application value in other underground mining areas.
