Abstract: The article provides a review and analysis of various systems for maintaining the operational equipment of mining equipment. Particular attention is paid to the system of planned preventive repairs operating in coal mines since 1983. It is noted that it requires significant financial costs, significant downtime of equipment in scheduled repairs. Depth of planning does not allow sharp changes in the operating conditions of equipment. And when they change, the whole system collapses. The lack of flexibility makes the system very rigid. It has been established that a modern system of maintenance and repair of equipment according to its actual technical condition requires constant monitoring of the equipment. This is possible only if there is a significant staff of technical diagnostics specialists and a high production culture. It is proposed to organically combine the complexes of preventive and reactive repair systems applied both to the fleet as a whole and to the machine or its individual unit, in particular, which will allow for the modernization of the PPR system, taking from it the best - planning and existing planning standards, and add to it flexibility.
