Abstract: In order to achieve the comprehensive management of “photovoltaic + ecology” in coal mining subsidence areas and build a green, low-carbon and circular economy system, the Ningdong coal mining subsidence areas in Ningxia was taken as the research area. The goal is to accurately obtain comprehensive information on ground deformation, utilizing technologies such as synthetic aperture radar, laser scanning, oblique photography, and Internet of Things monitoring, coupled with 3D geological modeling and GIS technology, to conduct key technical research on comprehensive monitoring of ground deformation information at the State Power Ningdong Photovoltaic Base. A high-precision, multi-scale three-dimensional monitoring system has been established that integrates “space(aerospace)- air(low altitude)- ground (surface, underground)”; Established a multi-dimensional data warehouse consisting of mining survey data, ground deformation monitoring data, digital photogrammetry data, LiDAR data, mobile monitoring data, 3D geological models of coal mining subsidence areas, oblique photography models, digital elevation models, etc; A construction plan for a comprehensive information monitoring platform for ground deformation has been proposed, and a Web GIS based comprehensive information monitoring system for ground deformation in coal mining subsidence areas has been developed with independent intellectual property rights, which has been applied in the field; it has achieved integrated information supervision of “space, air, and ground”, display and analysis of three-dimensional scenes above and below the ground, dynamic sensing of coal mining subsidence area boundaries, and comprehensive early warning of geological disasters, among other functions; it can provide technical support for the four-in-one system of “real-time perception, dynamic evaluation, early warning analysis, and comprehensive remediation” to induce disasters in underground coal mining, and assist in the “photovoltaic + ecology” comprehensive governance.
