Replacing Routine Inspections with Mobile Scanning: How Renjiazhuang Mine Implements "Special Management" for Special Equipment

Original article: https://cli.im/article/detail/1855

With the sustained and rapid development of mining operations, the variety, quantity, and operational scale of special equipment continue to expand. To ensure daily management and safe operation, Renjiazhuang Mine has implemented a "special management" system utilizing WeChat QR code scanning, achieving digital implementation and application for special equipment management.

How does mobile scanning replace routine inspections to make equipment checks safer, more convenient, and authentic while preventing false or missed inspections?

This challenge occupied Wang Wei, an employee from the Electromechanical Power Department.

After obtaining leadership approval, Wang Wei developed a web module during the Spring Festival holiday. The system integrates equipment information, inspection content, and requirements into a backend management platform, generating a unique QR code for each device.

After 28 days of development and 21 days of testing, the system entered trial operation on February 7 and officially launched on March 1, receiving widespread recognition across departments.

Through mobile GPS positioning, the system not only prevents false/missed inspections but also clearly displays equipment "health status," simplifying workflows and eliminating paper waste.

Wang Wei explained: "Each device corresponds to a QR code. Scanning via WeChat reveals complete information including parameters, serial numbers, and responsible personnel, eliminating manual documentation searches. Dynamic records like spot checks, repairs, and maintenance are continuously updated to form comprehensive equipment profiles."

When abnormalities are detected during inspections, submitting a fault report triggers automatic notifications to responsible personnel. Inspectors can manually alert maintenance teams. Post-repair, technicians add resolution details (text, images, forms) and notify relevant parties, creating closed-loop management. All records are archived for fault analysis and preventive measures.

After system implementation, managers and operators can view inspection reports anytime via mobile devices, monitoring completion status and receiving expiration alerts to ensure timely task execution. This guarantees regular equipment maintenance and prevents oversight.

This marks the first QR code application for special equipment management in coal mining. By tracking equipment lifecycles—recording usage duration, maintenance frequency, and component replacements—the system optimizes equipment utilization and extends service life.
