Norilsk Nickel has implemented mobile lidar scanners at all mines in the Norilsk Division.16 lidar laser systems have been installed, which are used daily at all mines of the Norilsk Division to take pictures of mine workings, mineral warehouses on the surface, cleaning space, mineral warehouses on the surface and other industrial facilities where personnel access is restricted for security reasons.

Thanks to IT systems, all historical geological and surveying documentation of mines was digitized, digital models of the company's deposits were built, and the mineral resource base was refined. Detailed design allows enterprises to accurately calculate the volume of extracted rock mass and plan mining operations.

"Before the introduction of lidar scanning systems, the survey was carried out using a total station, which is capable of measuring only in a stationary position, without taking into account the characteristic irregularities of underground mine workings and with a range of only 35 m. To shoot 100 m, it was necessary to rearrange the total station three times, and all measurements were carried out manually," says Sergey Sobolev, head of surveying control and audit of mining projects at the Department of Mineral Resources of Norilsk Nickel.

To date, lidar scanning technology is the most effective method of obtaining a digital model of underground workings and the Earth's surface. The device is capable of performing high-precision shooting of mine workings in motion in minutes. Visualization of 3D shooting takes place in real time. A highly detailed and accurate digital model of the scanned space is obtained due to the instant processing of reflected signals from light laser beams by the device. The shooting range reaches 120 m, which is comparable to a 40-storey skyscraper.
