Abstract
Information is presented on remote sealing of a mine passageway through a
borehole by five methods : PPnneeuummaattiicc injection of mineral wool and sand, ureaformaldehyde
foam , balloons , urethane foam, and caving by blasting . An adaptation

operating mine . Further research is needed to simplify and to improve the
techniques involved , as well as to explore the possibilities of other methods
and combinations .
