| Bibliography: | 43-1239/TG An integration processing system of three-dimensional laser scanning information visualization in goaf was developed. It is provided with multiple functions, such as laser scanning information management for goaf, cloud data de-noising optimization, construction, display and operation of three-dimensional model, model editing, profile generation, calculation of goaf volume and roof area, Boolean calculation among models and interaction with the third party soft ware. Concerning this system with a concise interface, plentiful data input/output interfaces, it is featured with high integration, simple and convenient operations of applications. According to practice, in addition to being well-adapted, this system is favorably reliable and stable.

Effective implementation of goaf detection and accurate acquisition of its spatial characteristics including the three-dimensional morphology, the spatial position as well as the actual boundary and volume, are important basis to analyze, predict and control disasters caused by goaf. In recent years, three-dimensional laser scanning technology has been effectively applied in goaf detection [3,4]. Large quantities of point cloud data that are acquired for goaf by means of the three-dimensional laser scanning system are processed relying on relevant engineering software to generate a three-dimensional model for goaf. Then, a general modeling analysis and processing instrument are introduced to perform subsequent three-dimensional analysis and calculation [5,6]. Moreover, related development is also carried out in fields such as three-dimensional detection and visualization of hazardous goaf, detection and analysis of unstable failures in goaf, extraction boundary acquisition in stope, visualized computation of damage index, aided design for pillar recovery, and three-dimensional detection |
