Maintenance and repair of equipment are extremely important during its operational process. Since the equipment is operated by construction personnel, regular maintenance and repairs are beneficial for the safety of the workers and also contribute to extending the equipment's lifespan.

1. Improve the methods of piling machine equipment maintenance management and strengthen the management of equipment use and maintenance. Under existing conditions, enterprises should highly prioritize the training of skills and quality of personnel involved in equipment use, maintenance, and repair. Further perfect the system of routine maintenance, including three-level maintenance, spot checks, shift checks, regular maintenance, patrol inspections, and handovers, as well as civilized production. Enterprises should make maintenance decisions based on modern maintenance theories, industry characteristics, equipment features, working environments, and the role of equipment in coal production. They should establish and strictly enforce equipment management rules and regulations; select appropriate maintenance methods, including post-maintenance, preventive maintenance, planned pre-maintenance, and condition-based maintenance, gradually forming a scientific and new maintenance management model with coal mining characteristics.

2. Equipment maintenance and repair system. The maintenance management system should be based on the equipment user manual and operation records, establishing a regular planned maintenance system according to the lifespan of components. For example, if the operation records show that the lining of a slurry pump has a lifespan of 1000 hours, the planned maintenance cycle for the lining of that equipment would be set to 980 hours, thus controlling equipment faults at an early stage. Due to the specificity of piling machine equipment repair work, maintenance work is divided into onsite repairs and planned repairs. Onsite repairs are based on issues identified by electromechanical staff during equipment operation, representing a passive form of maintenance; planned repairs, however, are preventive maintenance, an important task to ensure equipment performance and integrity.

3. Implement green maintenance. Green maintenance of piling machines is a modern maintenance model that integrates environmental impacts and resource utilization efficiency. Its goal is not only to maintain and restore the specified state of products but also to meet the objectives of sustainable development. That is, during the maintenance process and after the product maintenance until its disposal, the product should maintain and restore its original specified state. At the same time, the generation of maintenance waste and harmful emissions should be minimized, thereby reducing environmental impact. Additionally, it should provide good labor protection for personnel and ensure high resource utilization efficiency.
