Abstract
The cylindrical stone blocks of large diameters (300-800 mm) are used as shafts of papermaking machines, which set up exclusive standards to fissuring of stone. The present paper describes a special device for separation of cylindrical stone blocks from the bottom without destruction of the surrounding rock mass shutting out appearance of fissuring in the stone.
