Abstract:

Safe production is the primary goal of each mining enterprises.But the existence of goaf has caused potential safety hazard for mine production，and also seriously affected the subsequent planning of ore mining.How to accurately grasp the goaf data and scientifically reveal the geometric characterization and mutual spatial relationship is of prime importance for the mine safety and production.Nevertheless，there are many difficulties in measuring goaf，such as the personnel and equipment into difficulties，poor accuracy and high risk.But the 3D laser scanning technology can overcome them.In this paper， taking the Jiaojia gold Wangershan mine as an example，we introduces the contour boundaries and spatial orientation of unknown goaf based on 3D laser scanning technology，so as to lay a solid theoretical foundation for the goaf treatment and resource recovery.

Key words: 3D laser scanning, safe production, goaf, Jiaojia gold mine
