Hydrogeological situation at Mir diamond mine put under stricter monitoring

17 august 2017
Currently, the main task is to ensure the safety of miners and rescuers on the mine’s level of -210 meters, where search works are carried on. To this end, ALROSA specialists monitor the water level in the quarry and in the underground mine every two hours based on the work plan. The monitoring is carried out by Rietl vz-4000 laser scanner and a Leica ts-06 total station. The obtained measurements permit to create a 3D model of water accumulated on the bottom and estimate its volume. These parameters are laid in the schedule of filling the mine with water and make it possible to calculate the degree of danger for the rescue operation. In addition, the pumps installed for dewatering are equipped with ultrasonic flowmeters. The readings of these devices are taken into account when assessing the risk of search and rescue operations.
During the past day, eight 51 men strong paramilitary units of Russia’s EMERCOM were sent to the mine to continue search and rescue works. Cargos were thrown off from helicopters into the quarry above the underground mine, which helped to drain some part of water (more than 2000 m3) from its pit. In total, 77 meters of underground workings were cleared from 1 685 m3 of rock mass.
