Constant growth of the depth of mining and the intensification of mining pressure manifestations in the dynamic form,
result in the realization of special geomechanical investigations on the problem of protection from rock bumps. It is known,
that conditions and forms of rock destruction during underground mining are defined by a complex influence of three main
factors: total level of static and dynamic stresses within the elements of mining constructions, conditions and speed of
loading of the latter from the side of the loading system – rock massif. Rock bumps, as a rule, are timed to fleeting massif
movements of underworked massif rock. The analysis of rock-bump hazard conditions with the account of the regime of
loading reveals significant influence of the inequality in physical, especially strength properties of rock and ore building up
a massif, on the character of distribution of stresses and deformations within the loaded elements of mining constructions.
The results of the analysis are introduced of ore deposits development conditions and rock destruction forms during
underground mining in conditions of higher stress with the purpose of assessing their influence on the mechanism of rock
destruction in dynamic form.
Key words: rock pressure control; geomechanical conditions; rock-bump hazard; dynamic rock pressure manifestation;
static stress; dynamic stress.

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.

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 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.
