The 1990s were characterised by the closing down and liquidation of underground mines, which, under new conditions, failed to cope with the economic and environmental criteria introduced. The fast initial liquidation of underground mines led to surface faults and destruction of mine workings, collapses of shaft tops, escape of methane to the surface and resultant explosions, and contamination of mine water discharging from or pumped out of flooded mine workings, as a result of improper liquidation of the mines. The fact of the matter has prompted the state mining authority to seek the method of technical liquidation of underground mines, which would be a final solution to the issue without any impact on the society or the environment.
