Designing Material Handling System Based On Volumes Extracted Using UAV Based Photogrammetry

The mining industry is an adopter of data-driven technologies coupled with policy implementation and technological development. Location of mining activities and relevant stakeholder involvement are key to sustainable solutions surrounding the mining sector. The volume of excavated material plays a key role in designing slurry transportation units and processing plant capacities. Standard accuracy and equipment for mine survey guide the determination of excavated volumes to avoid mismatch of equipment versus the material to be moved. Mine survey consists of collecting, processing, storing and analyzing spatial information sets for accurate volumetric in order to design appropriate materials handling system, plant capacities and proper mine schedules. This research seeks to develop an efficient slurry transport system and easily achievable mine plan with due recognition to equipment deployment using Unmanned Aerial Vehicles (UAV)-based photogrammetric mapping systems for volume calculations. Considering the time consumed, safety, accuracy and frequency in collecting and analyzing survey data for volumetric analysis using conventional surveying techniques, there is need to employ UAV-based photogrammetric mapping systems for volume calculation of excavated material to design an appropriate slurry transport system for efficient production planning. The UAV captures stereo photographs using a digital camera and registers projection centre coordinates using Global Positioning System (GPS) and Inertia Measurement Units (IMU) in what is generally known as direct geo-referencing. Photogrammetry software is then used to stitch together the geotagged photographs with high overlap captured from multiple angles. The software generates very dense 3D point clouds and the result is a 3D surface model for higher accuracy volume calculations safe and faster than before. This is then input in ArcGIS software to calculate the volume with respect to a given depth, the volumes then play a key role in decision support to design a slurry transport system using P&ID software, to design the pipeline layout all this with respect to piping standards and codes.
