The press service of the Russian Ministry of Emergencies reported to RIA Novosti that rescuers had to dig for 5 more meters to reach 4 miners cut off by fallen rock in the Ziminka mine in Prokopievsk.
By 17.30 Moscow time 8 meters of the main tunnel were cleared out.
At the same time works are carried out in a by-pass tunnel: there 9 meters were negotiated with 13 meters left, according to the Emergencies Ministry.
The decision to dig a tunnel to bypass the obstruction was taken due to strong earth movements which made it dangerous to clear the obstruction in the main tunnel.
