Methane release in drainage holes ahead of coal face
Soviet Mining - Tập 50 - Trang 60-64 - 2014
The authors have revealed features of local minimum methane concentration in drainage holes and causes of the methane concentration zonality. The offered hypothesis on methane release in drainage holes accounts for zonal disintegration of rock mass around an excavation.
Galena oxidation mechanism
Soviet Mining - Tập 48 - Trang 354-362 - 2012
The authors study the process of the oxidation of galena in the liquid phase of flotation pulp of alkaline pH in terms of the formal kinetics. Kinetic schemes of the process are considered. The theoretical kinetic parameters of the overall oxidation reactions of galena are defined as a result of calculations. The most probable rate-determining steps of the galena oxidation, as well as the equation...... hiện toàn bộ
Combination Methods of Hematite-Braunite Ore Processing
Soviet Mining - Tập 54 - Trang 126-140 - 2018
The material composition and process properties of hematite–braunite iron–manganese ore from Yuzhny Khingan deposit of Russian Far East are studied. The source of manganese in the ore is mostly braunite. The mineralogy and petrography of the ore and products of its processing are characterized. Noble metal minerals are found in the ore; the gold contains platinum and silver admixtures. Producibili...... hiện toàn bộ
Transient aerodynamic processes in ventilating shafts with a drip
Soviet Mining - Tập 11 - Trang 134-137 - 1975
Design principles and accuracy of an inertial surveying system
Soviet Mining - Tập 34 - Trang 357-366 - 1998
Catastrophic consequences of prolonged weak action on free-flowing material
Soviet Mining - Tập 31 - Trang 15-19 - 1995
Prolonged weak action on free-flowing material leads to gradual accumulation in it of irreversible changes and it may lead to loss of stability. The work was carried out with support from the Russian Fund for Fundamental Research (RFFR), grant No. 94 05-16428.
Earthquake impact on pitwall stability
Soviet Mining - Tập 48 - Trang 595-608 - 2012
The paper reviews calculation methods for pitwall stability under seismic impact of earthquakes. The physical modeling allowed determination of seismic vibration influence on sliding of probable wedge of failure, the latter is assumed to be bounded by stressed sliding surfaces. Finally, the authors advise on choice of the pitwall stability factors for seismically active areas.
