The production of sized coal directly at the face of an open pit in the cyclical mining technology involves the introduction
of a processing unit and the addition of a transport unit with a technological vehicle with specialized containers installed
on it. The processing unit, at the outlet from which the sized coal is produced, includes crushing and sorting plants,
a storage bunker, and conveyor lines. Technological vehicle is designed for transportation of specialized containers with
the produced sized coal from the face to the daylight surface. The use of containers for the delivery of sized coal will
ensure the safety of its qualitative and quantitative characteristics. The structure and the parameters of the introduced
mining and transport complex depend on the specific mining-engineering conditions of the development and the possibility
of using the equipment offered by the industry in these conditions. In the paper, various variants of technological schemes
for placing the complex of mining and transport equipment in the face of an open pit are considered. The possibility of
allocation and the field of application of the complex of processing equipment in mining-engineering conditions of face
development with an excavator ECG-5A has been determined.

Key words: sized coal; mining and transport complex; mining-engineering conditions; technological transport; technological
vehicle; processing unit.

The article introduces the main scientific and practical results of the development of geoenergetic fundamentals for
the underground mining of ore deposits by means of disclosing physical essence of the phenomenon of zonal
encapsulation of mine workings. The phenomena, processes and regularities of mine workings encapsulation by an array
with the definition of shape, size, number of energy zones, sinusoidal-damped stresses, and annular deformation areas
are systematized. An energy theory of the study of the parameters of zonal encapsulation of mine workings has been
developed: the shape, size, quantity and conditions for the formation of energy zones and the boundaries of possible
destruction of the massif. Power-law dependences of the change in the dimensions of adjacent energy bands are
established, the ratio of which is constant from the size and shape, the depth of deposition and the physical properties of
the array enclosing the working. The thermodynamic theory of studying the state of the rock massif undisturbed by
the excavations has been improved by taking into account the processes of redistribution of geoenergy flows and entropy
exchange in an undisturbed massif with the isolation into a separate research method – entropy. The sinusoidal-damped
dependence of the autowave oscillations of stresses in the massif disturbed by the workings on the gradients of density,
temperature, gas and water saturation of rocks has been specified. Geoenergetic approaches to the selection of traces
of preparatory workings, calculation of the parameters of their fastening are recommended. The parameters of performing
stoping in energy zones of safety capsules are justified. The estimation of efficiency of geoenergetic technologies and
realization of industrial introduction at underground development of ore deposits is introduced.

Key words: rock massif; stress-strain state; geoenergy; safety capsule of working; geoenergetic zones.

The work considers the problems of recurring mining of lost ore reserves. Recurring development of deposits contributes
to the improvement of the subsoil use completeness. Primary development is based on the method of maintaining
overlying rock and stoping zone, whereas under the recurring excavation it is usually necessary to meet significant
integrity damage of ore massif and enclosing rock. For this reason the production of the lost ore reserves with traditional
methods is near-impossible. When selecting the method of underground recurring development it is necessary to take
into account the factors which determine the practicability of these works: when excavating ore with low content of metal
the factor of production cost acquires crucial importance; in case of works in the disturbed massif, the factor of safety is
especially important; works in disturbed zones requires significant resources to develop and maintain the workings, thus,
the method of development has to provide significant production output. By way of example of lost ore production, brand
new technology is suggested, the essence of which consists in the additional output of caved rock mass out of the
stopping zone in heavy suspensions.

Key words: recurring development; rock integrity; lost reserves; additional output; heavy suspensions.

The article is devoted to the problem of reducing the dilution of metal ore by overlapping and enclosing rock in
the production process in underground mining. Some information is given about the state of knowledge of production quality management processes under the development systems with a collapse of ore under the overlapping rocks. Development results are introduced of a complex field structure under a flexible tree-rope and steel cable overlappings. The practice in the application of overlappings of different structures depending on the conditions of development in the uranium-mining industry is described. Overlappings strength determination methods are systematized and typified. For the conditions of polymetallic deposit, economic-mathematical comparison of alternatives with the collapse of the core technology and under the overlapping is fulfilled. The problem of improving the quality indicators of the produced ore are formulated through the separation of ore and rock by the overlappings, including the substantiation of the separation efficiency, optimization of overlappings design for each type differentially, the release of lost ore under the overlappings effectiveness determination, and overlappings structure development. The article systematizes the engineering methods of reducing dilution magnitude with the release of the previously lost ore which are applied in ore mining, also by means of loadbearing and separating overlappings application. It is predicted that the prospects of the direction include bridges costcutting through the development of new composite materials. It is shown that improving the quality of previously lost
produced ore and ore extracted with overlappings is an essential element of expanding raw-mineral base and mining
enterprises economic rehabilitation. The results of the study are of interest to some existing mining enterprises and some
mining enterprises under construction.

Key words: production; lost ore; overlappings; mine; raw material base; economy; enterprise.
