The technologies of selective excavation of coal seams, embedded in traditional development systems, are considered;
they help to preserve the natural quality of coal from various layers by excluding preliminary loosening and dilution,
separate formation and delivery to the surface of homogeneous in quality of several flows of rock mass, the possibility of
carrying out separate processing of coals of different quality, creation of several production lines "extraction–processing",
working simultaneously. The existing experience of selective excavation for systems of development by short and long
wall faces with the use of modern means of mechanization is generalized. Proposed: layout of the continuous miner,
which provides for a separate excavation of seam layers of a complex structure in one pass, schemes for the formation
of two or more flows of rock mass of different quality due to the maintenance of technological or organizational pauses
with the use of means and methods of communication. In the direction of the separate processing of flows of rock mass
of various quality, technical solutions have been developed for the production of hydrofluoric acid out of power generating
coal with industrial content of platinum as raw material for the subsequent production of platinum, and from coals with
an industrial content of osmium – sodium perosmate as a raw material for the subsequent reduction of osmium to metal.
Key words: coal deposit; integrated development; valuable chemical elements; selective excavation; short face; long wall
face; separation of rock mass flows.

The article describes methodological approaches to advanced mineral loss accounting and regulation during opencast
development of deposits with complex mining and geological conditions. As an example, mineral loss indicators are
introduced when developing Kostanoksky plot of Chanvin deposit of limestone used for the production of caustic soda.
Actual loss level is determined, exceeding 30% of raw materials total production. The main reasons are introduced of
advanced loss of limestone in comparison with in the project loss. It has been stated that with a detailed exploration
of the massif of limestone, karst zones and zone with a higher content of clay bedded in the form of veins in zones of
higher rock jointing, have not been identified. As the result of blasting operations, mixing of karsted and clayed areas,
and pure limestone takes place, together with its pollution up to the values exceeding the allowable ones; it leads to loss
in the balance reserves of minerals during extraction. The article gives recommendations over the calculation of the level
of loss when developing complex faces, which are characterized by rock intermittency with productive layer of limestone
and karst zones.
Key words: limestone; production loss; Chanvin deposit of limestone; clogging; dilution; karst zones; loss regulation.

Within the boundaries of the Ural region at the present stage rare sensible earthquakes are recorded with magnitude from
3–4 to 5–6 on the MSK64 scale, which accompany the making of the newest Ural orogen. The majority of the focuses of
sensible earthquakes of the region is allocated within the boundaries of the Middle Ural seismodomen, which can be
considered as the area of possible generation of the focuses of sensible earthquakes in the future. Seismodomen is timed
to area of interference of submeridional Ural mountain belt, which divides the East European Craton (EEC) and West
Siberian Plate, and the north-eastern border of the Russian Plate of the East European Craton. Within the boundaries of
the Middle Ural seismodomen, four seismocentres are distinguished, they are Dobryansky, Serebryansky, Bilimbaevsky
and Zlatoust-Miass-Kyshtymsky, where the most part of sensible earthquakes focuses is located, and consequently, the
most part of seismic energy of bowels in the region. The generation of the focuses of the strongest (with magnitude from
4.5 to 5.0) sensible earthquakes in 1788–2017 was registered within Serebryansky and Bilimbaevsky seismocentres,
situated in the central part of the Middle Ural seismodomen, timed to the interference area of geodynamic influence of the
Main Ural Fault and the north-western boundary zone of the Russian Plate of the East European Craton. The possibility
of generation of the focuses of sensible earthquakes with magnitude from 4.5 to 5.0 and with 6 points strength on the
MSK-64 scale within the boundaries of the given region is roughly rated as once in 80–120 years.
Key words: the newest orogen; earthquake activity; focuses of sensible earthquakes; seismocentres; the area of possible
generation of the focuses of sensible earthquake.

The analysis of recommendations over the mine engineering parameters and the sequence of mining Nyurbinsky open pit down to the depth of 570 m with the use of four-wheel drive hinge articulated dump trucks has been fulfilled. The two variants of open pit development have been worked out. For practical implementation the variant have been recommended, which involves local reconstruction of open pit edges without changing its surface borders. The formulae are suggested for the preliminary calculation of the depth of transition to exposing with steeply inclined crosses-over with the use of four-wheel drive dump trucks. It has been stated that in the variant suggested, the rational depth of transition constitutes 330 m. Suggestions to ensure the conditions of efficient exploitation of hinge articulated dump trucks under the development of deep horizons of an open pit have been substantiated, which consist in the use of haulage berms of variable width, motor transport robotization, and lower open pit horizons exposure with marginal automobile tunnels
of spiral shape.
Key words: open pit; motor transport; haulage berm; pit edge stability coefficient; steeply inclined crosses-over; tunnel; transition depth.

The construction is proposed of a demountable cutting bit with disk milling cutters (DRDF-244.5-2) equipped with two rows
of cermet cutting structure, which performs complex impact of hard-alloy teeth on rock, including crumpling, shearing,
cleaving, and cutting. Possible operating modes of the drill bit DRDF-244.5-2 are investigated: stable mode, anti-roll mode,
and blocked mode. Modeling of interaction of rock-destroying elements with the bottom surface of a borehole is executed
under the stable work of the drill bit. The expressions for the calculation of the moments of the tooth-wheel milling cutters with
two rows of hard-alloy cutting structure, as well as the rational axial forces ensuring stable work of the drill bit in rocks of
different fortresses are determined. The article introduces the diagram to determine axial force ensuring stable operating
mode of drill bits DRDF-244.5-2 with different quantity of tooth-wheel milling cutters. It has been determined that double-row
cutting structure of the drilling device with rotary-cutting milling cutters provides the diversification of the sphere of rational
exploitation of rotary-cutting drill bits. Blasthole drilling with the drill bit DRDF in stable operation mode in rocks with vide range
of physical and mechanic properties change is ensured by the control over the axial force depending on rock hardness.
Key words: axial force; rock hardness; blasthole drilling; drilling device; stable operating mode.
