Data collection without touching the object or aerial photography using drones, commonly referred to as photogrammetry, is slowly replacing mapping survey work. Survey activities during mining exploitation aim to determine the total volume of overburden and coal mined. The aim of this research is to ascertain the discrepancy in volume between the photogrammetry data processing, which uses varying numbers of Ground Control Points (GCP), and the total station data processing. The volume of the total station survey considered accurate is 441.404,769 BCM. The volume difference of Cut and Fill Pit A using a drone with the volume using a total station when using 7 GCP points is 1.210.533,553 BCM, or 274,25%; using 10 GCP points is 602.623,863 BCM, or 136,52%; using 13 GCP points is 404.010.038 BCM, or 91,53%; using 16 GCP points is 299.430,558 BCM, or 67,84%; and using 19 GCP points is 166.655.453 BCM, or 37,76%. More GCP points mean a closer photogrammetry volume to the total station volume, according to this research.

摘要

Data collection without touching the object or aerial photography using drones, commonly referred to as photogrammetry, is slowly replacing mapping survey work. Survey activities during mining exploitation aim to determine the total volume of overburden and coal mined. The aim of this research is to ascertain the discrepancy in volume between the photogrammetry data processing, which uses varying numbers of Ground Control Points (GCP), and the total station data processing. The volume of the total station survey considered accurate is 441.404,769 BCM. The volume difference of Cut and Fill Pit A using a drone with the volume using a total station when using 7 GCP points is 1.210.533,553 BCM, or 274,25%; using 10 GCP points is 602.623,863 BCM, or 136,52%; using 13 GCP points is 404.010.038 BCM, or 91,53%; using 16 GCP points is 299.430,558 BCM, or 67,84%; and using 19 GCP points is 166.655.453 BCM, or 37,76%. More GCP points mean a closer photogrammetry volume to the total station volume, according to this research.
