Kan-i-Gut mined cave, located in Kyrgyzstan, is one of the most morphologically complex cavities of mixed genesis. For the first time, a 3D model was developed for this cave by comparative analyses and computer processing of cave maps and mine surveyor plan and profile, obtained from different sources. The methodology of transferring graphical data into digital format is described. Primary morphometric parameters of the mined cave are gathered, and 3D images of its main parts are presented. Essential morphological changes due to vast collapses during the last 50 years were discovered.
