Meanwhile, the first well exceeded the mark of 160 meters (out of 262 needed), the second – 62 (out of 205). A fourth rig arrived on site to drill an additional well.
At a CoES meeting, chaired by regional governor Vasili Orlov, it was reported that 63 cubic meters of soil were removed from the rubble overnight and that 50 percent of the concrete was poured into one of the three waterproof lintels.
The best specialists in the country participated in the rescue operation at the Pioneer mine.
“Vyacheslav Aleksandrovich Rogachev is one of the most professional employees of the largest Russian company engaged in this type of work – the OGK group. He came especially to help us carry out drilling operations with the highest possible quality,” the governor said.
In total, 226 people and 29 teams participate in the rescue operation.
