Determination of the Operating Time and Residual Life of Self-propelled Mine Cars of Potassium Mines on the Basis of Integrated Monitoring Data

Article preview

Statistical data on the reliability of self-propelled mine cars (SPMC), operating in the potassium mines of the Verkhnekamskoye potassium and magnesium salts deposit are analyzed. Identified the main nodes that limit the resource SPMC. It has been proven that the most common failures of self-propelled cars are the failure of wheel hubs, bevel gears and traveling electric motors. The analysis of the system of maintenance and repair of mine self-propelled cars. It is indicated that the planning and preventive system of SPMC repairs is characterized by low efficiency and high material costs: car maintenance is often carried out upon the occurrence of a failure, which leads to prolonged downtime not only of a specific haul truck, but of the entire mining complex. A method for assessing the technical condition of the electromechanical part of a mine self-propelled car by the nature of power consumption is proposed. This method allows you to control the loading of the drives of the mine self-propelled car, as well as to assess the technical condition of the drives of the delivery machines in real time. Upon expiration of the standard service life of a mine propelled car specified in the operational documentation, its further operation is prohibited and the car is subject to industrial safety expertise. As part of the examination, it is necessary to determine the operating time and calculate the service life of a mine self-propelled car outside the regulatory period. A method has been developed for determining the residual service life of mine car on the basis of instrumentation control data in the conditions of potash mines.

Residual life assessment gears coarse-grained open transfer of mining machines based on the local changes of their surface hardness

Article preview

The effect of local changes in the surface hardness of the end surfaces of teeth of coarse-grained gear transmissions mining machines. Represented by patterns of change of the surface hardness is not the type of reference to the loading. The estimation of the value of destruction of samples. Proposed to assess the remaining amount of coarse-grained gears with consideration of changes in the local surface hardness developed technique.

Improving the strategy of electric rope shovels technical service by entering into the technical service system elements of Total Productivity Maintenance

Article preview

To date, there is need to review the existing rigid system of preventive maintenance and the transition to a more progressive system, which provides maintenance and repairs on its actual state, in which the need for repair work is based on a preliminary examination and the results of the diagnosis and monitoring of major nodes excavator. Pays special attention to the concept of TPM (Total Productivity Maintenance) for the maintenance of mining excavators.

Probabilistic approach to the assessment of energy transmissions of mining machines

Article preview

In article the review of methods of a theoretical estimation  of  a resource of elements  of  cars is presented. Perspectivity of the thermodynamic approach is shown at the analysis of an expenditure of a resource by system elements. Presented a probabilistic approach in determining the energy source.
