An Automated Georeferencing Technique for Multi-Temporal Stope Point Clouds for Downstream Geotechnical Analysis
Dibyayan Patra, Simit Raval, Pasindu Ranasinghe +2
The increasing use of UAV laser scanning in underground mines has enabled frequent acquisition of 3D point clouds from challenging environments such as stopes, generating large vol…
From 3D Perception to Safety Reasoning: A Graph-Based Framework for Real-Time Underground Mine Monitoring
Pasindu Ranasinghe, Simit Raval, Dibyayan Patra +2
Underground coal mining requires personnel and heavy equipment to operate within shared, confined, and poorly illuminated spaces where hazards such as equipment proximity violation…
Towards Integrated Rock Support Visualisation in 3D Point Cloud of Underground Mines
Dibyayan Patra, Simit Raval, Pasindu Ranasinghe +2
The effectiveness of rock support in underground mines depends on the interaction between installed rock bolts and the structural fabric of the surrounding rock mass. However, disc…
Development and Validation of an Integrated LiDAR-Camera System for Real-Time Monitoring of Underground Longwall Operations
Pasindu Ranasinghe, Bikram Banerjee, Simit Raval
Real-time spatial monitoring in underground longwall operations is challenging due to methane-related safety risks, poor visibility, elevated thermal loads, spatial confinement, an…
Automated Discontinuity Set Characterisation in Enclosed Rock Face Point Clouds Using Single-Shot Filtering and Cyclic Orientation Transformation
Dibyayan Patra, Pasindu Ranasinghe, Bikram Banerjee +1
Characterisation of structural discontinuity sets in exposed rock faces of underground mine cavities is essential for assessing rock-mass stability, excavation safety, and operatio…
