III. Equipment Planned Maintenance Management System: This system is established to keep equipment in good working condition at all times, to address any defects in the equipment promptly, to ensure the quality of maintenance work, to extend the equipment’s service life, to save time spent on maintenance, and to reduce maintenance costs. 1. Equipment maintenance is divided into major repairs, medium repairs, minor repairs, major overhauls during system (unit) shutdowns, and after-maintenance repairs. The costs of major repairs are covered by the major repair fund ； Costs for medium and minor repairs are covered by production expenses ； The costs for major shutdown overhauls of the system (equipment) are paid separately according to the project and type of overhaul. 2. Implement scientific and civilized maintenance by strictly following the relevant technical procedures; the enterprise’s equipment and power departments must exercise strict control over the use of funds allocated for major repairs. Establish reasonable maintenance quotas, improve maintenance techniques, and gradually extend the service life of equipment. 3. Develop plans for major, medium, and minor equipment repairs based on the maintenance intervals and the problems identified during equipment inspections. The equipment maintenance plans are formulated simultaneously with the production plans, issued at the same time, and subject to inspection and evaluation at the same time. A maintenance task order must be issued for any maintenance work. 4. The equipment maintenance plan is prepared by the workshop. The balance of power allocation for plant (mine) equipment is determined and issued after approval by the plant (mine) manager in charge. When a maintenance plan is proposed, a plan for spare parts, materials, and tools should also be submitted simultaneously. The annual plan is submitted in the first 4 months of the year ； Quarterly plans are submitted 1 month before the quarter begins ； Monthly plans should be submitted 15 days before the month. 5. For the major maintenance shutdown of the system (unit), it is necessary to ensure that: (1) a deputy plant manager takes overall responsibility for the maintenance work. (2) Before the major overhaul, a preparatory leadership team for the overhaul should be established to be responsible for implementing the overhaul tasks, preparing materials and construction resources, arranging labor forces, and formulating plans for starting up and shutting down the equipment. (3) The personnel responsible for organizing and directing the major maintenance work must have unified planning, unified command, and coordinated actions. It is necessary to achieve the “three orientations” (that is, orientation towards the masses, orientation towards the grassroots level, and orientation towards production) as well as the “five arrivals at the site” (that is, ideological work arriving at the site, production supervision arriving at the site, material supply arriving at the site, design and research work arriving at the site, and living services arriving at the site). Pay close attention to the “four key stages”: parking, replacement, maintenance, and pressure testing for commissioning. (4) During the major maintenance, strict quality inspections and completion acceptance procedures must be carried out to ensure that the maintenance tasks are completed on time, in terms of both quality and quantity, so as to achieve a successful first trial run. After the maintenance is completed, a summary evaluation should be conducted. (5) Work together with relevant departments to ensure safety and prevent accidents. 6. Strictly and carefully implement the equipment maintenance plan; if adjustments are indeed necessary, approval procedures must be followed. Adjustments to the plans for minor and medium repairs of equipment are approved by the Equipment and Power Department of the factory (mine) ； The major maintenance plan is adjusted on a yearly basis in June, organized by the Equipment and Power Department of the factory (mine), and submitted for approval to the higher-level supervising authorities. 7. Technological innovations achieved through major and medium-scale repairs of equipment (such as structural reforms or the use of new materials and components) must be reported by the workshop to the plant (mine)’s equipment and power department, along with drawings for explanation; implementation is permitted only after approval. Major innovations must be submitted by the Plant (Mine) Equipment and Power Department to the higher-level competent authorities for approval. 8. A major repair plan is required for equipment overhauls. For complex projects, it is necessary to draw network diagrams. The major repair plan includes: inspection items, quality requirements, project schedule, labor force, spare parts, materials, requirements for special tools and equipment, commissioning and acceptance procedures, safety measures, etc. Once the major repair plan for the equipment is finalized, the relevant departments must ensure the supply of materials, spare parts, and prepare the necessary labor force. Before construction, the Equipment Power Department takes measures to ensure the smooth completion of the major repair work. 9. When performing equipment maintenance, it is necessary to strictly follow the procedures for equipment handover and adhere to the safety and technical regulations for maintenance work. The construction unit must complete the required procedures such as signing a maintenance task order and obtaining a fire permit before starting the maintenance. The production workshop is responsible for handling the equipment that has been taken out of service; once it is deemed suitable, it is handed over to the construction team, and dedicated personnel are assigned to assist the workers with any matters related to safety. Safety guardrails or markings should be installed at the construction site to ensure safe maintenance work. 10. Equipment maintenance must strictly follow the maintenance plan and procedures. If there are changes needed in the schedule or scope of the maintenance work, or if issues arise regarding quality requirements, it is necessary to report this to the workshop or the Equipment and Power Department, so that relevant personnel can be assembled promptly to address the problems. 11. Quality control must be ensured during equipment maintenance, by combining self-inspection, mutual inspection, and professional inspections, and this approach should be applied throughout the entire construction process. The main load-bearing components must have certification of conformity. The completion acceptance of major equipment overhauls is organized by the Equipment and Power Department ； The major overhauls of general equipment, as well as the completion inspections for the medium-scale overhauls of all equipment, are organized by the workshop ； The construction unit must ensure that the work is completed, all materials are cleared away, and the site is tidy.
