Ground subsidence due to underground mining could cause a series of damage to surface structures and farmland and change surface and surface drainage patterns. During the past few decades

a number of subsidence prediction techniques have been proposed. Ground subsidence disaster caused by mining is the worst form in all kinds of engineering subsidence. The ground subsidence of mining is a main subject in disaster control and prevention in engineering. GIS （geographic information system） as a new digitization technology is widely used in geotechnical engineering

and its advantages in data management and data visulization are remarkable. For building up an effective system of ground subsidence damage evaluation based on GIS

the 3D ground subsidence calculation model

data organization method and data visulatiza-tion methods have been given

and application of the methods are discussed. A spatial model for predicting and analyzing surface subsidence has been developed and is being integrated into a GIS software-MapInfo. In the condition of upland and low mountainous region

the visual dynamic calculation method of ground subsidence is provided. The approaches of visualization for DEM and ground subsidence basin have been established

and moreover

we have done research on visual superposition for 3D relief map and ground subsidence basin. Based on the 3D ground subsidence calculation model

subsidence damage evaluation method and data visualization method

a system of ground subsidence damage evaluation based on GIS is build. The system have been used in many mining subsidence damage evaluation projects.
