GOAF PRECISE DETECTION AND THREE-DIMENSIONAL MODELING IMPLEMENTATION BASED ON CMS

A large amount of goaf in the process of mine production was formed,goaf has caused potential safety trouble for mine production,and also seriously affected the subsequent orebody mining. The accurate knowledge of the actual three-dimensional shape and three dimensional space position of goaf is an important basic work of empty zone stability analysis,the implementation of an empty area of safety management and disaster control. It has high efficiency and good visualization for us to use CMS system to detect the goaf. This paper introduces the Goaf detection research status and the basic principles and using methods of CMS,and then introduce goaf modeling methods using 3D laser scanning technology.
