ALROSA held space radar monitoring surface displacement in areas such kinds of diamond deposits.
According to information received, the company facilities are located in seismically stable condition. Shifts of the earth's surface, though there are, but they are minimal and within acceptable standards and tolerances.
The first series of radar satellite imagery territory Udachninsky Mining took place in the period from June to October of last year. At the beginning of January 2017 we were received the first data that formed the basis of a dynamic model of vertical displacements of the earth's surface that occurred on the territory of Udachninsky GOK over the study period. The following series of pictures will take place from June to September 2017.
Studies are needed for the timely identification of possible displacements of the earth's surface above the underground mining sites, strains boards and ledges quarries, as well as natural and man-caused displacement structures located near of the deposit.
Monitoring method using satellite radar interferometry has advantage over terrestrial geodetic observations satellite surveying. It enables coverage of large areas that the company, taking into account the large area of activity of mining and processing enterprises, is important. The above set of measures intended to improve industrial safety in mining operations on subsoil operated facilities.
Regular independent assessment of the displacement distance with millimeter precision on the whole area of the earth's surface industrial areas GOKov company, which is about 5,000 hectares, will be carried out during the 2017-2018 period.
