The paper justifies the relevance of developing and implementing automated onboard systems for operation data and maintenance recording in heading-and-winning machines. The analysis of advantages and disadvantages of existing automated onboard systems for operation data and maintenance recording in heading-and-winning machines for potassium mines are presented. The basic technical requirements for the design, operating algorithms and functions of recording systems of mining machines for potassium mines are formulated. A method of controlling operating parameters is presented; the concept of the onboard automated recording system for the Ural heading-and-winning machine is outlined. The results of experimental studies of variations in loading of the Ural-20R miner's operating member drives, using the VATUR portable measuring complex, are given. It is proved that existing means of objective control of operating parameters of the URAL-20R heading-and-winning machine do not assure its optimal operation. The authors present a technique of analyzing the data provided by parameter recorders that allow increasing efficiency of mechanical complexes by determining numerical values characterizing the technical and technological level of potassium ore production organization.

The frequency of maintenance of electromechanical equipment depends on the plant, which uses and runs this equipment. Very often the maintenance frequency is poorly correlated with the actual state of the electromechanical equipment. Furthermore, traditional methods of diagnosis sometimes cannot work without stopping the process (for example, for equipment located in hard to reach places) and so the maintenance costs are increased. This problem can be solved using the indirect methods of diagnosing of the electromechanical equipment. The indirect methods often use the parameters in the real time and seldom use the parameters of traditional diagnostic methods for determination of the resource of electromechanical equipment. This article is dedicated to developing the structure of a special automated control system. This system must use the big flow of the information about the direct and indirect parameters of the equipment state from plants from different areas of industry and factories which produce the electromechanical equipment. © Published under licence by IOP Publishing Ltd.

By means of the technique of local analysis, the presence of a wide variety of tungsten and tungsten-containing accessories was first revealed in the composition of lithium-fluoric granites of the Far East, which represents a substantial similarity and regional peculiarity of these rocks. It was concluded that the tungsten accessory mineralization might be considered as an indication of the genetic relationship of the mineralization of the East Asian tin-tungsten zone to the Pacific rare-metal granites. © 2014, Pleiades Publishing, Ltd.

US universities are leading the way in technology commercialization, while universities in Russia lag far behind. This paper discusses the best American practices, as well as the main issues of technology commercialization at the US universities. As an example, we consider the experience of the University of Maryland, College Park. In the next section, we turn to technology commercialization in Russia, where it struggles for several reasons. In this paper, we propose that Russia can improve its technology commercialization by studying the example of the leading US entrepreneurial universities and implementing proper procedures. And the important overarching point is that Russian universities need to improve their collaboration with industry, and they need to develop new standards of administrative, research, and business activity that will promote innovation and entrepreneurship. © 2015 Springer Science+Business Media New York

The present paper contains a statement of basic provisions of the estimation method for the energy capacity of parts of mechanical transmissions of mining machinery. A method was substantiated for the assessment of the residual operation life period of large-pitch gears by means of regular hardness measurement of the superficial metal layer of the interaction gear surface. Patterns of gear hardness mutations of large-pitch gear transmissions were discovered. In order to investigate the influence of value and type of load upon the reduction of the operation life of the mechanical transmissions of mining machinery, an experimental fixture was built, and laboratory experimental work was done to study the destruction of non-standard elements. The strain parameters of the samples were determined, as well as local metal hardness changes in the areas adjoining the destruction spots. Crucial strain corresponds to the increased hardness with the limit value for the material given in the destruction area. In accordance with the experimental data, it was determined that the observed local hardness changes take place in areas where the stress is increased over the proportionality limit, and the work of the destruction forces assigned to the density of dislocations immediately adjoining the destruction plane is expressed as hardness increment, the latter being a constant value. © 2016 Published by Elsevier Ltd.

Seismic recordings of methods of the reflected and refracted waves contain information on features of a geological structure of the studied areas. This information is concluded in kinematic (arrival times) and dynamic (amplitudes) parameters of waves. In a method of the reflected waves for determination of elastic properties of the studied geological environment in the course of processing of records widely are used not only kinematic, but also dynamic properties of waves. In a method of the refracted waves kinematic processing is carried out generally. On productive kinematic cuts the provision of refracting borders and value of boundary speeds (without amplitudes) is, as a rule, represented. Dynamic properties of records are attracted only at a stage of correlation, definition of kinematics and the nature of waves. The way of receiving the method of the refracted waves dynamic coal mines at which values of amplitudes of waves characterize difference of elastic properties in an entry point of the refracted wave in refracting layer or an exit from it is offered.

The methodological bases for determining the energy resource of mechanical transmissions details for mining machines are considered. Based on the analysis of the accumulation of damage in metal gears, a method of estimating residual life of coarse-toothed wheels by periodically measuring the hardness of the surface layer of the teeth is justified. The regularities in change of hardness of coarse-tooth gear, conditioned by a change in metal strength properties that take into account the micro- and macromechanisms of plastic and elastic deformation, distortion of the metal crystal lattice with formation and movement of vacancies and dislocations. Experimental setup was built and the results of laboratory experiments are given related to the process of destruction of non-standard samples under different loads. Comparison of dimensions and hardness values of the sample allows concluding that a larger deformation corresponds to a greater increase in hardness, their limit value for the material being in the fracture zone. It is established that the detected changes in the local hardness occurs in areas of increased stresses above the limit of proportionality and the work of fracture forces attributed to dislocations density adjacent to the fracture plane expressed in terms of hardness increment is constant. © Published under licence by IOP Publishing Ltd.

The results of theoretical and experimental studies are presented that focus on validating the manufacturing parameters of the peat raw production under conditions of applying a developed manufacturing scheme of the modular peat enterprise operation. The conducted studies revealed the dependences of the gravitational dewatering efficiency factors on the initial conditions of dehydration caused by the values of the pile height and moisture content. An example of the evaporation rate calculation at the convective and radiative-convective heat supply is given for the average data of summer months. The calculation results indicated an increase in the role of evaporation in the gravitational dewatering of peat raw under the favorable weather conditions. © 2010 RJPBCS.
