Diamondiferous garnet lherzolite from the V.Grib kimberlite pipe: relationship between subduction, mantle metasomatism and diamond formation

Записки Горного института
The article presents the results of a comprehensive study of diamondiferous lherzolite from the V.Grib kimberlite pipe. The composition of rock-forming minerals (olivine, orthopyroxene, Cr-diopside, Cr-pyrope) in terms of major elements mainly ...

Stress-strain state modeling of a mine working face near gas-dynamic hazard zones

Записки Горного института
The driving of mine workings in strong dolomites at the “Internatsionalny” mine using the drill-and-blast method is complicated by gas-dynamic phenomena, which manifest as rock and gas outbursts.
