Maintaining the existing volumes of a coal production at the level o f 80 mi l l ion tons, and its

increase up to 100 mil l ion tons requires mining very low and low coals. That part of the reserves is

much greater than the average-width part of coal reserves in Ukraine. Therefore to improve the

mining technologies of such reserves is the actual task to maintain the fuel balance of the country.
