The miners are also demanding the development of the coal industry, an end to mine closures and the payment of salaries and other social benefits, according to an UNIAN correspondent.
The protesters have blocked the traffic on Hrushevskiy Street, on which the Cabinet Office and the parliament are located, and are holding a rally near the main entrance to the building of the Cabinet of Ministers.
More than 100 policemen are standing nearby, behind a metal fence.
As reported, more than a thousand miners gathered on Wednesday for a rally in Kyiv to protest at the problems in the industry. They said they planned to block all traffic on Khreshchatyk Street.
