Abstract： The safeguarding and examination of ancient saltpeter mining sites embedded within karst caves confront myriad obstacles from the constraints imposed by darkness and intricate topographical features.A pivotal challenge among these is the precise documentation，portrayal，and delineation of the unique features and configurations of such sites. Three-dimensional （3D） laser scanning technology emerges as a comprehensive and meticulous approach to data gathering and analysis，offering robust underpinnings for the preservation and exploration of cave saltpeter mining sites. This comprehensive study harnessed 3D laser scanning technology to meticulously measure five exemplary leaching systems，two saltpeter mining systems，two remnants of saltpeter mining operations， and two stone beds within the esteemed Jinfo Cave，situated in Nanchuan，Chongqing，to accurately depict the site's expanse and capture the intricate spatial information，and eficiently established a 3D model that quantitatively embodied the intricate architecture and distinguishing attributes of the cave saltpeter mining sites. In terms of archiving and visualizing the data pertaining to cave saltpeter mining sites，3D laser scanning technology has proven to be swift，efficient，and adept at fulfilling measurement requirements with efficacy.

Key words： three-dimensional laser scanning；cave saltpeter mining site； point cloud processing; Jinfo Cave
