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 Outdated system controlling the rotational speed of shafts drive motor gives rise to considerable dynamic loads on components of mechanical transmissions for shuttle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.

In the article the process of destruction of the array of Cambrian clays by cutting, as a dynamic contact problem of mechanics, solved with using the software environment ANSYS Worbench, is observed. The obtained results are verified on a laboratory bench setup with experimental investigations. Analysis of the results of computational and laboratory experiments shows that in the framework of theoretical and experimental approach to solving problems of continuum mechanics, as an integral part of the basic research a finite element method can be used, which lets adequately and with sufficient accuracy to determine the power and energy indicators of process of destruction of the clay arrays by cutting. A characteristic feature of the process of destruction of flooded Cambrian clays is significant plastic deformation of rocks at the contact with the cutter. The separation of the elements of destruction from the array occurs under the action of shearing stress by the formation of shear cracks. High viscosity of arrays of Cambrian clays defines a large share of energy consumption on their destruction, comparable in value to the energy intensity of the process of cutting of hard coal and salt rocks. The use of computer simulation can significantly reduce the duration and increase the accuracy of design calculations at designing of the actuating devices of mining machines.

Prospects of ecological technologies development in the Russian oil industry have been developed in the paper. Reducing the negative impact on the environment is inextricably linked with the development of applied technologies. On the basis of scientific, systematic and comparative analysis we have identified major environmental issues arising from extraction, processing and use of oil and the directions of their solution. The greatest negative impact on the environment is provided by such factors as sludge formation, burning of associated gas, increased accident rate and the use of fuel oil. A number of problems in the field of environmental safety in the oil industry may be avoided by using innovations. In this work, we have assessed the prospects for reducing the negative impact on the environment through the application of modern engineering solutions in the field of ecology. In order to reduce environmental impacts and economic costs, it is primarily proposed to develop technologies in the area of safe waste management, modernization of treatment facilities and prevention of oil and oil products spills.
