Justification of the rational parameters of chambers of the third stage extraction while underground iron ore mining
Zubko, S.; Kononenko, M.; Petlovanyi, M. (2015)The width of stope chamber of third stage mining in contact with week rocks of hanging wall is justified. The calculation technique of mining methods with backfilling is improved. -
Kinetic features of the dissociation process of gas hydrate deposits
Sai, K.; Petlovanyi, M.; Prokopenko, K. (2019)The research is aimed at revealing the theoretical features of the kinetics of the process of dissociation of natural gas hydrates, the accounting of which is useful in designing technologies for their development. The ... -
Peculiarities of geological and thermobaric conditions for the gas hydrate deposits occurence in the Black Sea and the prospects for their development
Bondarenko, V.; Sai, K.; Petlovanyi, M. (2019)The actuality has been revealed of the necessity to attract the gas hydrate deposits of the Black Sea into industrial development as an alternative to traditional gas fields. This should be preceded by the identification ... -
Physicochemical mechanism of structure formation and strengthening in the backfill massif when filling underground cavities
Petlovanyi, M. V.; Zubko, S. A.; Popovych, V. V.; Sai, K. S. (2020)The strength and microstructural properties of the backfill massif have been studied and assessed when filling underground cavities that pose a threat of mine rocks collapsing in the process of mining mineral deposits. It ... -
