Monitoring technology of open mining works with using UAVs.
Monitoring technology of open cast mining with the use of drones is cost-effective, as the cost of surveying works using the UAV complex is much lower than traditional surveying.
In any mining company to perform pre-construction of the subject required the efforts of several specialists to prolonged (weeks) period of time. It is a traditional technology monitoring of open cast mining. To improve performance, perhaps the use of aerial photography with the use of light UAVsweighing less than 10 kg. In contrast to manned aviation, the devices of this class requires no special airfield. A sufficient condition for take-off and landing is the open area of size 50 m x 70 m. Shooting at the UAV for these purposes can be performed at low altitude (200-600 m).
The technical capabilities of modern UAV systems (photographic, system navigation, control, and communications) provide greater efficiency of obtaining results in comparison with satellite imagery, a higher resolution (3 cm at a point) and minimal dependence on weather conditions.
When you work with the UAV operator does not require special piloting skills and extensive training, thanks to the full automation of the management of the complex. For regular shooting all of the objects of the mining enterprise is enough one or two employees. The performance of the complex allows for one light of day to perform the aerial view of the area up to 70 km2.
When carrying out open mining operations UAVs can be used for various tasks: monitoring work, mapping, and estimates of volumes of mine workings and dumps.
Monitoring technology of open cast mining with the use of UAVs suggests:
– aerial photography and preparation of high resolution orthophotos at a relatively low cost,
– construction of three-dimensional digital terrain models for the purpose of survey software,
– providing information for monitoring and planning of mining operations.
In processing the images transformirovalsya in the orthophoto, which is used to create new and update existing topographic maps and plans. In addition, it is possible to integrate with any GIS software.
– stereo photogrammetric methods can produce estimates of the volumes of excavations of pits according to the three-dimensional model of the terrain. This approach is also economically viable, as the cost of imaging operations using a complex UAV is much lower than traditional surveying,
– in comparison to satellite imagery, the materialsreceived from the UAV, more responsive, have high resolution (3 cm in point-to-pixel), low price the minimum order and are always relevant and do not depend on the time of year and weather conditions
– thanks to the full automation of complex operator-UAV does not require special piloting skills and long training.
