The article examines methodological tools of the estimation of ecological-economic efficiency of wastes application from
the subsoil user point of view, who replaces fresh raw material by the secondary raw material; and from the society point
of view. Recommendations over the estimation of commercial effect are given as well as some suggestions on generation
of the effect conditioned by the economy of ecological expense: pay for environmental pollution and waste dumping,
resource tax, etc. When determining social-economic effect, the appeal to the newly developed reserves is provided,
which are more frequently situated in little-developed northern areas with poor infrastructure, and with poor and
morphologically complex ores, which is confirmed by financing structure of geological exploration and results of geological
study of subsurface. Because of the increase in the content and remoteness the consumption of raw material increases
for 1 t of commercial element, and, correspondingly, expenditure connected to minerals recovery at primary resources
field development and transportation to the consumer increases. The presence of information about outbursts, faults, and
waste dumping allows estimating economic damage, conditioned by pollution of environment during resources
exploitation. The use of methodological recommendations permits taking reasonable decisions over wastes application
on the basis of ecological-economic efficiency estimation.
Key words: wastes; fresh raw material; commercial effect; ecological-economic efficiency.

Contour blasting with the method of “protective layer” at subroof zone breaking with horizontal blastholes allows shaping
a buffer layer in the process of blasting with 0.8–0.9 m thickness, which undertake load from contour-hole charges and
explodes with maximum possible delay against the latter. Near contact-split zone is necessary to keep rock roof from
contour charges blasting. It is stated that with decrease or increase of normal release charge mass the indicator of
explosion effect decreases and increases correspondingly, i. e. the value of calculated specific consumption of explosives
depends on the indicator of explosion effect. It is covered by the introduction of the function of the indicator of explosion

effect in calculation formula. In the course of the investigation around 360 m of upper layer were broken (in roof – by
stepped face) with the use of the given method. Positive results of experimental and industrial testing have allowed
recommending the given method to use at all open pit mines of mining metallurgical company Norilsk Nickel.
Key words: contour blasting; buffer layer; near contact-split zone; blasting cone; the function of explosion effect indicator;
relieving charge; “protective layer”.

The article examines some problems, connected with open pit excavating machine operating time. The methods
of calculating annual capacity are analyzed. Some contradictions that arise when calculating operating time of a mining
machine are revealed; they are described by various sources. The question is put about the repair cycle time tracking
purposefulness when determining annual capacity of an excavating machine. The article reveals the analysis results for
various periodicity types in between capital ones depending on the elaboration of in-service hours by an excavating
machine. Methodological recommendations to calculate operating days of an excavating machine in a year are revealed
with the account of repair cycle and specified operation ratio during the shift.
Key words: rock mass recovery; power shovel; shoveling machine; mining machine maintenance; mining equipment

Economic stripping ratio is the basic criterion of opencast mining efficiency under the determination of open pit outlines.
The purpose of investigation is development of methods with the account of iron-ore production competitive ability
conditions in the global market. At the heart of economic stripping ratio determination is the condition, that the price for
commercial output of the designed enterprise must not exceed prices for same commercial output in the global market.
The said condition realization is achieved analytically. At that the influence of profit rate at the final depth of the designed
open pit is taken into account. The worked out method of economic stripping ratio determination helped determining the
values of maximum allowable stripping ratios for Poltavsky GOK open pit, which provide competitive ability of iron-ore
commercial output in the global market at various values of profit rate.
Key words: open pit outline; economic stripping ratio; iron-ore concentrate; competitive ability of production.

Coal industry in Russia currently works in significantly complex conditions. This has an impact on enterprises profitability
and actualizes the use of modern means of coal mining with the purpose of cost reduction. The present article examines
the problems of “manless coal winning” technology development in conditions of underground mining. The functioning of
the introduced structure is possible on condition of the main equipment electric drives system modernization by means
of transferring them from uncontrolled mode to control mode. It should be noted that the introduced structure will allow
increasing the level of industrial security in shafts prone to sudden outbursts of gas and dust.
Key words: coal shaft; stoping area; energy efficient and safe technologies; manless coal winning; methane release; dust
formation; innovation structural control scheme.
