The scanning target is a metal mine goaf located approximately 650 meters underground. We conducted detailed and accurate scanning of the goaf and built a complete 3D model of the mine cavity, providing comprehensive data support for subsequent backfilling operations.
The mine features narrow passages, complex surroundings and crisscross routes. Long-term disuse has rendered some areas hazardous and inaccessible to conventional scanning equipment. Poor lighting and single access passages across most of the goaf further complicate field work. Traditional surveying methods fail to map the internal spatial structure efficiently within a short period.
The mine environment of this project is complex, with rough terrain and pooled water. Some areas are hazardous and cannot be fully covered by conventional scanning methods.
Additionally, the project requires rapid data collection of the goaf, calculation of backfill volume and formulation of a final backfilling and remediation plan. Under such circumstances, traditional surveying techniques are no longer adequate.
The GoSLAM mobile 3D laser scanning system features real-time performance, high accuracy, ease of use and high efficiency. Operators can start one-touch scanning simply by holding the device. Combined with its powerful mapping engine, the mobile scanning mode drastically boosts work efficiency to meet diverse project requirements.
Achievements
1.Point Cloud Data
GoSLAM directly acquires poiDnt clouds with real geodetic coordinates to support the design of backfilling plans.
2.Volume Report
Import the point cloud data into post-processing software to generate a volume report with one click for quick calculation of filling volume.
3.Model Generation
Models can be generated from point cloud data for professional analysis in geology, hydrology and other fields.
4.Cross-section Drawings
Slice data every two meters according to point coordinates for the design of retaining walls and closure walls.
Key Advantages
The GoSLAM mobile mapping system is built on SLAM (Simultaneous Localization and Mapping) technology. It works independently of GNSS receivers such as GPS, enabling self-positioning and incremental 3D mapping during movement in unfamiliar indoor and outdoor environments. Operators can start scanning simply by holding and moving the device. It is user-friendly and delivers high efficiency for hybrid data processing.
This device is integrated with a powerful mapping system featuring high robustness, great adaptability to low-feature environments, excellent data restoration and consistency. When paired with an RTK system, it can directly output high-precision absolute coordinate data.
In addition, The GoSLAM mobile 3D laser scanning system is equipped with a full range of supporting components, including color modules, backpack kits, vehicle-mounted kits, UAV kits, quadruped robot kits and extension poles. It delivers excellent point cloud colorization solutions and multi-platform mounting solutions, suitable for a wide variety of scanning scenarios.
