Effect of mechanoactivated chemical additives on the process of gas hydrate formation
(2018-02)
This study addresses the production of gas hydrate of methane with a high gas-hydrate-forming content in a solid phase in the isolated system at T=274 K and pressure of 5 MPa and presence of mechanically activated rocks ...
Physicochemical mechanism of structure formation and strengthening in the backfill massif when filling underground cavities
(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 ...
Research into thermobaric processes of methane gas hydrates formation
