On August 20, the Ventilation Team organized a seminar for all monitoring and control personnel to discuss on-site issues and usage precautions related to the monitoring system sensors. The meeting focused on key challenges and difficulties in sensor operation and maintenance, further standardizing operational procedures and enhancing the ability to address on-site issues.
During the meeting, technician Huang presented on the theme of “On-site Issue Investigation and Usage Precautions for Safety Monitoring System Sensors,” using actual underground case studies to explain the four-step method for troubleshooting sensor failures: “Ask” to accurately capture the underground conditions at the time of the failure, including production shifts, surrounding equipment, and abnormal handling measures; “Look” to comprehensively check sensor data, records, and the status of related equipment; “Measure” to strictly test key indicators such as basic error and response time; “Think” to analyze the causes comprehensively and provide direction for problem resolution.
In the section on usage precautions for sensors, participants focused on discussing daily maintenance content, summarizing key points such as regular calibration, timely cleaning of dust-proof components, reasonable load distribution, ensuring stable power supply, and standardized wiring installation. They also clarified the calibration cycles, maintenance focus, and replacement standards for different types of sensors, such as methane and carbon monoxide, particularly emphasizing the need for enhanced protection of sensors in special working environments.
This seminar, through in-depth experience sharing and case analysis, outlined typical issues in the on-site application of sensors and consolidated the team’s consensus on fault diagnosis and handling. Everyone agreed that continuously strengthening on-site practical capabilities and deepening system understanding are key to ensuring the stable and reliable operation of the monitoring system. In the future, the Ventilation Team will continue to rely on such specialized communication mechanisms to promote the accumulation and sharing of technical experience, solidifying the first line of defense for mine safety monitoring.
