The article covers the issues of increasing the efficiency of tunneling&cleaning combines “Ural”, widely applied at domestic potash mines. It is pointed out that it is possible to provide rational parameters of the process of destroying potash arrays with cutting tools of the executive bodies of mining combines. This assumption is based on the assessment of the drivers load which will reduce the specific energy consumption for ore extraction and will reduce the number of small unenriched classes in breakage products. The authors substantiate rational regime parameters of the operation of the planetary-disk executive bodies in the Ural combines. A method for automatic control of the tunnel&cleaning combine “Ural” is proposed, which ensures the implementation of the process of destruction of the potash massif with rational cutting parameters on the basis of information on the drivers load.

The article presents the results of experimental investigations of the magnitude and nature of change loads drive of mine shuttle car VS-30 used to deliver ore to extraction chambers in potash mines. The design of program-recording complex "VATUR" developed by employees of the department "Mining Electrical Engineering" Perm National Research Polytechnic University. In the investigation of operating modes of the drive of self-propelled mine wagons were carried out measurements and recording the instantaneous values of voltage and current of electric motors, calculated values of active and apparent power consumed by the motor pump stations and bottom conveyors of mine shuttle car. Carried out investigations modes of operation and changing loads on the units and details of the tram drive. It is proved that the operation of electric motors of the mine shuttle cars increased characterized by a systematic overload. Outdated system controlling the rotational speed of shafts drive motor gives rise to considerable dynamic loads on components of mechanical transmissions for shuttle cars. Significant loss of time causing the reduction in technical performance longwall set of equipment of potash mines arises during the maneuvering operations and unloading ore from shuttle cars. Based on the analysis of the change of loading drives and statistics of dangerous failures were justified the technical solutions to improve the reliability of mine shuttle car. The recommendations to increase the efficiency of transporting potash in the longwall set of equipment, improving maneuverability of self-propelled cars and reduce downtime for unloading are given.

Any technological process including metallurgical processes is supported by the control system operation, accompanied by large information flows to be formed. However, the most part of this information is not used by specialists due to restricted capabilities of a human being that is, in fact, incapable of processing such information flows. It has been demonstrated that process control is significantly influenced by the human factor. This paper contains a methodology to process production information that permits the process personnel to use its potential in a more rational way to control the process. An approach has been reviewed to studying metallurgical processes using the analysis of indirect indicators of process management, namely the spectral density and auto-correlation function of main process parameters. A method to separate useful signals from noise has been studied. A method has been given to check the ACS management efficiency using primary material flows. The adopted methodology for processing experimental data permits interpreting the obtained results for their further practical application to develop new algorithms for process control and improve the existing control system.
