Abstract
At present, self-propelled equipment of foreign firms, which is characterized by high efficiency of use and high cost, is widespread at Russian mines. The low availability factor (0.7) and technical utilization factor (0.6), which characterizes the level of organization of the repair service, indicate insufficiently effective use of self-propelled equipment. In addition, there is a pronounced lag of repair systems, the basis of which were static repair standards established by deterministic methods, from the developing means of mechanization. This situation can be corrected by the adaptive system of maintenance and repair (M&R). Its basis is a subsystem of collecting and processing of the primary information about operation and repair of machines, the main source of information about the reliability of self-propelled equipment are observations during operation. The quality of the estimation of machine reliability depends on the quality of the collected information, which is subject to the requirements of reliability, completeness and homogeneity. Objective evaluation of machines reliability must be done only when the data about their work under specific conditions are received systematically. The form of recording the information about repair and operation of self-propelled machines and the scheme of forming the array of data about reliability and operating conditions are proposed.
