OPTIMIZATION OF PROCESS OF PRESSURE OXIDATION-SORPTION (POXS) OF REFRACTORY GOLD BEARING CONCENTRATES
The
results of POX of refractory gold-bearing concentrates using halide-ion
as a lixiviant for precious metals and activated carbon as an adsorbent
are given. It was found that gold did not recover to the solution when
halide was added during POX. Silver partially dissolved in the solution.
When halide-based reagents and activated carbon were added during POX,
gold dissolved and loaded onto the activated carbon. Experiments were
performed with different concentrations of sodium chloride. It has been
established that sufficient sodium chloride concentration for gold
leaching is 5 g/l. The analysis of the experiments conducted with
different loading of activated carbon showed that the amount of coal
must be at least 6% on the mass of concentrate.The degree of sulfides
oxidation was 67.7–99.8%. The maximum gold recovery was 98.6%. This
treatment process of refractory gold-bearing concentrates combines
sulfide oxidation, dissolution and adsorption of precious metals. The
results of the metals recovery achieved using this process can be
compared with the recovery during POX-cyanidation. In this case, sodium
cyanide was not used. This allows the reduction of capital and
operational costs due to the absence of cyanidation, CIL and
detoxification of leaching tailings circuits.

EXPERIMENTAL VALIDATION OF ELECTROCHEMICAL AND PHYSICOCHEMICAL APPROACHES TO STABILIZATION OF FERROSILICON SUSPENSION PARAMETERS
Under
conditions of altered kimberlite ore processing, investigation of
methods for prevention of oxidation and decomposition of ferrosilicon in
the TSS process circuit is undertaken. It is found to be necessary to
adjust the employed water-based system parameters up to certain values
of high alkalinity (pH), negative-value oxidation–reduction potential
(ORP), low mineralization and minimum oxygen content. It is shown that
the most efficient methods for altering acid-base and
oxidation–reduction properties of the water-based system in the
ferrosilicon suspension production circuit and in the TSS process are
the electrochemical effects on the test objects and the substitution of
highly oxidative air for inactive gas of nitrogen in the circuit of
ferrosilicon suspension stirring. The bench tests show that replacement
of air in the circuit of manufacture and storage of ferrosilicon
suspension by inactive gas of nitrogen ensures prevention of
ferrosilicon oxidation and reduction in ferrosilicon loss from 20 to 2%
on an average. Preliminary economic design yields that the integrated
implementation of the electrochemical treatment of water phase and air
substitution for inactive gas of nitrogen in the ferrosilicon suspension
manufacture circuit will allow reduction in ferrosilicon loss by 1% per
day relative to the overall ferrosilicon under circulation in the TSS
process circuit.

EXPERIMENTAL
VALIDATION OF EDT-100 EMULSION COMPOSITION ELEMENTS AND MECHANISM IN
THE CIRCUIT OF WASHING OF DIAMOND CONCENTRATES FROM FAT
Based on
the outcomes of a package of experimental and theoretical researches,
the author validates the water–emulsion technology of washing of diamond
concentrates from fat after adhesion separation and before
high-temperature drying, to reduce loss of crystals in further circuits
of finishing by X-ray fluorescence separation. Defatting of adhesion
separation concentrates under treatment by double-action water–organic
emulsion takes place due to solubilization and removal of hardly soluble
fat components from diamond crystals before high-temperature drying
circuit, which enhances diamond recovery in further X-ray fluorescence
separation. The composition of the water–organic emulsion and the
efficient operation mode in the circuit of finishing of adhesion
separation concentrates prior to thermal treatment are theoretically and
experimentally validated. The manufacture procedure, technology and
application sequence of the EDT-100 water–organic emulsion in the
circuit of defatting of adhesion separation concentrates before thermal
treatment are developed. The experimental research undertaken for
processing plants of ALROSA has shown that the efficiency of diamond
defatting under application of the developed emulsion technology reaches
87.7%, which 8.5 times higher than under standard conditions.

NEED FOR SLOWDOWN OF LIFTING VESSELS IN AN EMERGENCY BRAKING ON MINE HOIST INSTALLATIONS
The
paper analyzes the main shortcomings of the safety brake of mine hoist
installations only by applying braking force on the drive drum. In this
case, deceleration of vessel is carried out at the expense of the
weakening of rope tension, which will inevitably lead to significant
overloads of traction organ after stopping the lifting machine. Many
researchers have expressed the idea of selective braking mode, depending
on the position of the vessel in depending on the position of the
vessel and causes an alarm is triggered on the implementation of the
emergency braking. However, an effective method of reducing the dynamic
loads on the rope in the event of sudden braking of the laden vessel at
this stage is not offered. For example, the emergency braking of vessel
if it hangs of empty skip and speeding at the approach to the reception
platform complicated by the fact that the braking distance is limited.
In these cases, the known methods of reducing dynamic loads on the rope
not apply. In this paper it is proposed the implementation of a safety
braking under slowdown of lifting vessel. In this case the overall
slowdown of mine hoisting installation is increase and reduced the
weakening of the rope relative to the equilibrium state, and therefore
reducing the value of the dynamic loads after stopping the hoist
machine. This method will be useful for emergency braking for lifting
equipment with multi-rope traction friction. This method will reduce the
probability slipping on the ropes lining the drum at the safety stop.

FEATURES OF THERMODYNAMIC PROCESSES IN UNDERGROUND DEGASIFICATION PIPES MADE OF COMPOSITE MATERIALS IN COAL MINES
The
article is devoted to peculiarities of thermal processes in systems of
underground degasification pipelines using pipe made of composite
materials. In today's environment of mining systems in underground coal
mines have found the use of pipes made of fiberglass, thermal and
physical characteristics which differ substantially from steel pipes.
These differences have an impact on thermal and hydrodynamic regimes of
motion of a methane-air mixture through an underground vacuum pipeline.
The specificity of the process of heat transfer that occurs during
transportation in underground vacuum pipeline methane-air mixture from
the wells to the surface shows that its intensity depends on the
composition of the gas mixture, flow, temperature, pressure and
conductivity of the pipe material. The account features of the

LOW-COST RAPID METHOD FOR ASSESSING THE RISK OF THE GAS DANGERAT DRILLING AND TUNNELING WORKS IN COAL MINES
Typically,
gas-dynamic phenomena and increased methane emission in coal mines
occur in disturbed areas, so many regulatory methods for predicting
outburst in the world based on the search of tectonic disturbances of
coal in coal seams. But many of these methods have hardly used at high
speed tunneling, drilling and clearing activities, as necessary for
results a lot of time (especially if coal samples must be delivered to
the laboratory for the study).
Therefore, to improve safety in mines
is necessary to develop and use fast and simple methods and portable
devices for reliable prediction of disturbance coal that miners can use
without sacrificing productivity of tunneling, drilling and clearing
activities.
Such low-cost rapid method for assessing the risk of the
gas factor and a very simple and cheap desor-bometrs of new principle of
action developed based on research of methane desorption and sorption
in coal samples in a unique experimental sorption calorimetric complex
at IPKON of Russian Academy of Sciences and in gas-bearing coal seams.
They will allow all miners quickly improve safety of driving and
drilling on the base of more rapid, simple and reliable forecast of
disturbance of coal in the near-face zone even without the high expenses
of money and labor.
Their use will allow miners immediately see the
broken coal on the surface of the face or in the drilling culm in his
lower temperature with a thermal imager or an infrared thermometer
(pyrometer), and then quickly and easily identify at working the
gas-dynamic characteristics and residual gas content of coal using this

PARTICULARIZATION OF THE KEY TRENDS OF COAL FUEL DEMAND STIMULATION OF FUEL POWER STATION
In
article the key directions promoting increase in demand of thermal
power plant at coal fuel are concretized. The analysis of dynamics of
production and consumption of coal in Russia is carried out, the main
consumers of coal in domestic market are revealed. As a result of the
carried-out analysis it is established that for the considered period
(2000–2013) steady growth of coal mining is observed, in structure of
coal mining steam coal to which share about 80% fall prevails. thus
growth rates of production of steam coals are 0,2% higher, than growth
rates of production of the coked coals – 2,9% and 2,7% respectively.
Growth
of volumes of coal mining for the considered period is caused by
increase by 4 times of volumes of realization of coal in a foreign
market at simultaneous decrease in consumption of coal in domestic
market for 14% that puts the coal-mining enterprises into rigid
dependence on world market conditions. Negative dynamics of consumption
is observed and on steam coal, and on the coked.
In article authors
concretize the reasons constraining use of coal fuel in domestic market
which decision will promote stimulation of demand of thermal power plant
for coal fuel.
The main reason for decline in demand for steam coal
in domestic market there is a competition to gas which prices are
regulated today by the state, thus the prices of coal fuel are formed by
the market.
Questions of research of cost of coal mining and
electricity generation of thermal power plant for the purpose of
establishment of the major structure-forming factors and identification
of reserves for decrease in their sizes will promote decrease in average
value of a fuel component in structure of production prime cost of the
electric power which is at the level of 60% today (average value of a
coal component – at the level of 50%).
Growth of consumption of coal
fuel will provide release of the corresponding volumes of natural gas
for other directions of realization.
Key words: coal reserves
in Russia, production of steam coals, domestic demand for steam coal,
demand of thermal power plant for coal fuel, a ratio of energy costs,
cost of coal mining, cost of electricity generation of thermal power
plant.

ASSESSMENT
OF THE ECONOMIC LOSSES ASSOCIATED WITH THE CONDITION OF THE INJURY AND
WORKING CONDITIONS AT THE ENTERPRISES OF MINING COAL, BROWN COAL AND
PEAT IN THE RUSSIAN FEDERATION
Evaluation of economic costs and
losses in the mining of coal, brown coal and peat associated with
providing compensation to employees engaged in work with harmful and
(or) dangerous working conditions and industrial injuries and their
possible reduction as a result of changes in the labour legislation of
the Russian Federation in connection with adoption of the Federal law
«On special assessment of working conditions» is presented. The largest
share of the economic costs and losses before 2014 accounted for the
costs due to lost working time associated with unfavorable working
conditions and injuries. In this kind of economic activity it was about
11% of added cost of manufactured products and services. These losses
can be reduced by a factor two as a result of the reduction in the
number of employees who will be provided compensation for work in
harmful and (or) dangerous working conditions, as well as possible
decrease in the compensation.
Key words: employment injuries,
harmful and (or) dangerous working conditions, compensation, special

THE BLOCK-HIERARCHICAL HETEROGENEOUS ENVIRONMENTS
We propose a
new method of numerical modeling of microseismic noise in the rocks with
block structure. The key idea is to introduce large number of point
dip-slip sources, associated with different structural levels of the
block medium. The standard staggered grid scheme is used to solve
elastic equations. As an example we present a synthetic microseismic
noise for the three-dimensional inhomogeneous model of coal bedrock.
