SUEK says it has purchased six unmanned aerial vehicles (UAVs) with various modifications intended for aerial photography during surveying operations of its Kuzbass facilities, in the Kemerovo region of Russia.
The decision to develop the company’s fleet of UAVs was made after a test of aerial photography at SUEK’s open-pit mines in the Krasnoyarsk region and Buryatia, the company said. “After analysing the accuracy and detail of 3D terrain models obtained using UAVs, SUEK concluded that this technology could be used for surveying and land management in mining,” it said.
In August 2018, the Aerial Surveying Office was established as part of the technical directorate in Kuzbass. Today, the office is equipped with two Russia-made UAVs capable of making aerial photographs at a height up to 1 km, with a flight duration of two-and-a-half and four hours, respectively.
SUEK’s fleet also includes four compact DJI drones and a GNSS receiver that makes it possible to receive and process signals from all navigation satellite systems that exist today, it says. This latter device enables surveyors to locate UAVs during aerial photography.
Simultaneously with the procurement of equipment and staff training, the Aerial Surveying Office has made efforts to satisfy the requirements of the mandatory registration of UAVs with the Federal Air Transport Agency, to ensure compliance with legislation governing the use of Russian airspace, the process of aerial photography and the operation of UAVs, SUEK said.
The technology is helping the company solve a whole range of issues related to open-pit mining, such as evaluating the size of coal storage facilities, monitoring hazardous situations, updating topographic plans of work areas and surrounding territories, and monitoring the use of company land. The latter includes actual use of allotted land, the intended purpose of the land, reclamation, demolition control in buffer zones and property stock taking, the company said.
Anatoly Meshkov, Technical Director of SUEK-Kuzbass, said: “First of all, UAVs improve the efficiency and safety of surveying measurements and the accuracy of necessary calculations. We can now remotely control mining operations at almost any point and build digital enterprise models.
“Essentially, this is another step towards creating a ‘digital underground mine’ and a ‘digital open-pit mine’ to obtain the maximum amount of data for highly efficient management of coal production processes.”
