The invention discloses a 3D WebGIS prediction analysis method and system for surface movement deformation of a mining area. An oblique photogrammetry method is adopted to obtain real scene three-dimensional model data in an osgb format of the mining area, and monomer processing is carried out on key geographic elements. An ASP.NET Web application framework based on a B/S (Browser/Server) framework is adopted,a geospatial database of coal face subsidence prediction parameters and key ground feature elements of the surface of a mining area,a mining subsidence prediction module and a GIS (Geographic Information System) space analysis module are established. On the basis of a Cesium open source three-dimensional earth framework, layer control and display, 3D WebGIS three-dimensional space visualization analysis, mining damage level cloud picture drawing and statistical report output are achieved, earth surface movement deformation prediction analysis can be conducted, and meanwhile the working quality and effici
