"Device Name: Water-ring Vacuum Pump; Model: 2BEC87; Maximum Air Intake: 800m³/min; Operation Status: Normal; Maintenance Records..." Recently, at the Gucheng Coal Mine's surface gas pumping station, team leader Ji Chenhui immediately accessed complete equipment information by scanning a QR code.
As technology advances, digital-intelligent systems play an increasingly vital role in coal mine safety and efficiency. Implementing "QR code" labels for centralized process display and achieving "one-code access" to equipment information represents a new equipment management initiative by Gucheng Coal Mine's gas extraction team, exemplifying the mine's management innovation efforts.
Since the beginning of this year, Gucheng Coal Mine has set new quarterly coal production records. With increased output, prolonged equipment operation requires frequent lubrication and maintenance. Different equipment models, specifications, and maintenance materials previously demanded significant time for upkeep, documentation, and safety inspections.
"Scheduled inspections and maintenance are crucial for ensuring safe and reliable operation of gas extraction systems. Both routine checks and overhauls require accessing technical data and maintaining detailed records," explained Wang Dan, head of the gas extraction team. Technicians previously needed to consult over a dozen logbooks for updates, leading to inefficiencies and delayed documentation.
During a team meeting, staff proposed implementing QR codes on special equipment at gas pumping stations. "As a new information carrier and automatic identification technology, QR codes will greatly facilitate equipment management and maintenance," Wang Dan noted, sparking team-wide adoption.
The team analyzed daily maintenance data requirements, optimized data collection templates, and used CaoLiao QR code platform to create unique codes for each device. Printed QR codes were then affixed to major equipment.
Field technicians immediately recognized the benefits. Pump station operator Han Lingtong shared: "Equipment maintenance used to involve tedious logbook entries prone to errors. Now scanning QR codes allows direct data input, eliminating manual record searches."
"We implement 'one-code-per-device' management. These QR codes serve as digital IDs, linking directly to databases to display device names, parameters, and maintenance history. Compared to traditional manual records, code scanning is faster and more accurate," Wang Dan added.
The QR codes also enhance gas extraction safety. During equipment failures, technicians can immediately access operational data through codes rather than manual record searches, significantly reducing troubleshooting time and minimizing downtime risks.
"QR codes offer high storage capacity, strong traceability, and low-cost digital management - crucial for ensuring equipment safety," Wang Dan emphasized.
Post-implementation, the team maintains real-time updates of equipment inspection and maintenance records. When failures occur, technicians can trace issues through maintenance logs while comparing data across similar devices for faster fault resolution.
Technical staff can also predict potential issues through maintenance records and prepare solutions in advance. After repairs, maintenance personnel add detailed failure descriptions to complete closed-loop management.
All inspection and maintenance records automatically synchronize to backend systems. Managers can access historical data through code scanning or the workbench, enabling real-time monitoring.
This QR code implementation has streamlined maintenance processes while improving quality and efficiency. Moving forward, the team plans to expand applications through data integration, driving equipment management towards comprehensive digital transformation.
