The volume of water in the openpit mine at 4.00 pm local time was 33,000 cubic meters.At 3.53 pm, the water level in the mine shaft was at mark –222.2.The sensors of the automatic start of the first pump of the cage shaftwere activated as planned.The pump is operating in automatic mode, pumping the water inflow of 830 cubic meters per hour and keeping the water at the specified level.If the water inflow increases greatly, the second pump will be put into operation.The drained water comes to the main drainage system complex and then to the surface.

Based on the information about the increased volume of washouts in salt rock, the expert group of the Yakutniproalmaz Institute, together with the experts of the Institute of Mining of the Ural Branch of the Russian Academy of Sciences (Yekaterinburg), are recalculating the actual stability margin factor of the lower pit bench under which the workings are located.That is whyworks related to the controlled discharge of water from the open pit mine by focused explosions were not carried outin the afternoon.

It is planned to submit the results of the calculations to the emergency rescue centerby the morning of August 26.

While there is still a danger of an uncontrolled immediate inrush of water into the mine shaft, rescue works underground are forbidden.
