摘　　要：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.研发了集采空区激光扫描信息管理、空区激光探测点云数据去噪优化、空区三维模型构建及可视化显示和操作、模型编辑、剖面生成、空区体积及顶板面积计算、模型间布尔运算以及可与第三方软件交互等多种功能于一体的采空区三维激光扫描信息可视化集成处理系统。此系统具有界面简洁、数据导入导出接口丰富、集成度高及应用操作简便等特点。实践表明,该系统具有良好的稳定性和可靠性,且适应性强。

关 键 词：GOAF laser scanning visualization integration system 1 Introduction The goaf formed through underground mining of mineral resources is one of the main disaster sources threatening mine safety production [1 2]. 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
