Simulation of deposit parameters in underground development mining
(2018)
The article is aimed at improving development mining to
prepare an ore body for stoping by access ramps to provide comfortable
conditions and high technical and economic indices in underground
mining. ...
Scientific-practical results of monitoring anthropogenic influence upon environment of mining territories
(2018)
The objective of this paper is to improve the ecological
monitoring system and to take effective technological measures by way of
wastes neutralization. The scientific-practical results of monitoring ...
Scientific and methodological foundations to develop numerical hydrodynamical models of mine fields in Donbas
(2018)
The paper considers specific character of hydrogeological
problems arising during the whole cycle of a mining enterprise operation;
the most reliable their solutions are implemented in the context of ...
Fire resistance evaluation of reinforced concrete floors with fire-retardant coating by calculation and experimental method
(2018)
With the help of a previously developed technique based on the
solution of inverse and direct problems of heat conductivity, the fire
resistance of a hollow-core reinforced concrete floor with “Neosprei” ...
Parameters of selective martite ores disintegration in structured ore bodies deposits by borehole hydraulic monitors
(2018)
The work is aimed at determining parameters of advance
borehole stoping by hydraulic monitors leading to rational use of reserves
structured according to ore types at deposits by means of advance stoping ...
The study of melting process of the new plugging material at thermomechanical isolation technology of permeable horizons of mine opening
(2018)
The article presents the results of experimental and theoretical
studies, the purpose of which was to substantiate the technology of drilling
wells isolation using new thermoplastic composite material. The basis of ...
Mathematical modeling of tight roof periodical falling
(2018)
The paper proposes a method to determine of a coal seam roof
falling step basing upon the analysis of stress and strain state of the rock
mass area with mine workings formed as a result of coal preparatory and
extraction ...
Results of the experimental research of the heat-transfer jet pressure to the rock surface during thermal reaming of the borehole
(2018)
The performed analysis of scientific sources confirms the
existence of a small number of publications devoted to the experimental
research of the gasdynamics and plasmodynamics of jets used as a ...
Dependence of gas emission from the sources undermined by stope mine workings on the rocks displacement parameters
(2018)
The parameters are established in the work of the stope mine
workings and rocks displacement, which correspond to the maxima of gas
emission into the gas drainage boreholes. The angular and linear
parameters ...
Investigation of muck drawing in blocks with trapezoid sills
(2018)
The article is aimed at determining regularities of muck
drawing in blocks and developing the technology of enhancing of muck
ore parameters through shaping a trapezoid block sill. To confirm ...
