Geomechanical conditions of use of the utilized tails of enrichment of metallic mineral raw materials as the hardening stowage mix are proved. The grounds for the geomechanical balance control of the mountain mass preserving the Earth's surface by way of dividing it into safe areas according to their stress rate are indicated. The model of defining the economic and ecological efficiency of the technology using recycled processing tailings is suggested. © Metallurgical and Mining Industry, 2015.

Using the model of temperature distribution in the gas chamber in a separate environment Matlab Simulink Modeling, there simulated processes of heat transfer and thermal radiation along the height of the layer of pellets. The simulation results can be used when applied in industry ACS of heat treatment process of pellets. The model is flexible and considers the main parameters of the process annealing pellets. The resulting graphs of changes over time temperature distribution along the height of the layer of pellets are true. © Metallurgical and Mining Industry, 2015.

Purpose: On the basis of research of technical and economic indicators of mining and processing production to develop the model of formation and management of energy saving at the mining enterprises. Methodology: During this research the methods of the technical and economic analysis for an assessment of a moderrn energy consumption at the mining and processing enterprises, specification and synthesis - for identification of the factors influencing volumes of consumption of energy resources, system analysis - for generalization of the theoretikal and methodological principles of formation of power consumption optimum level of mining and processing production products were used. Findings: The offered model of organizational and economic energy saving at the mining enterprises allows to increase effective management of this process significantly. For definition of the directions of a correcting of organizational and economic and technical and technological actions for energy saving and improvement of system of material stimulation of the personnel of the mining enterprise it is necessary to carry out the monitoring of use of energy resources allowing to estimate expediency of further implementation of energy saving projects and appropriate technologies on natural and cost indexes and also will provide introduction of rational system of motivation of energy saving. Originality: Consists in system approach application in the expenses management of energy resources at the mining enterprises. At the operating level of management of the mining enterprise methodical ensuring motivation of the personnel of separate structural divisions to energy saving which is based on use of coherence of social and economic interests of the employer and hired worker is considered and allows to reach the maximum economy of energy resources of the enterprise taking into account the period and standards of their planning. Practical value: The developed model allows to define the actual expenses of energy resources and effectively to operate their use by production of iron ore production in the conditions of limited financial opportunities of the domestic enterprises.

Critical analysis of approaches for solution of the problem of increase of reliability and service life of open coarse-grained gears of spherical ore-pulverizing mills was carried out. The influence of physical mechanical properties of gear wheels material on the wear rate during running and set uniform wear of teeth contact point was determined. The abilities of their yielding surface plasma quenching were proved. © Metallurgical and Mining Industry, 2014.

New diagnostic features of instance detecting of operational defects occurring and significant impact on the fixed rotary machines loads growth, which cause a sharp reduction in their life, were developed, explored and suggested. The automation module of rotary machines operating condition control on the base of dynamic misalignment fact discovery was suggested. The module allows applying of unit maintenance circuit according to real situation, avoiding of unauthorized stops, examinations and interference in serviceable equipment, and thus eliminating of additional service costs. The calculations of economic benefits of the fixed diagnostic module use, profit from the implementation and payback period were carried out. © 2015. Metallurgical and Mining Industry.
