From the first days
of the mine’s existence it had to face serious difficulties associated with the mining and geological conditions: at first the dip angle in the mine field was gentle, then it reached 45 degrees. The mine was built in record time - in just 1 year. In March 1955, Zamchalovskaya No. 2 began to produce coal - its annual design capacity was 150 thousand tons. Also in 1950s, three more mines were laid: Zamchalovskaya No. 1, Zverevskaya No. 1, and Zverevskaya No. 2, which were part of the Gukovugol Trust.
