Description

Technical Field

[0001] The invention belongs to the technical field of coal mine underground gas detection, and relates to a self-checking coal mine underground gas inspection device and method for ensuring data authenticity. Background Art

[0002] Gas disasters are the main natural disasters in underground coal mines. Gas inspections are the basic link in gas disaster prevention and control, which can fully understand and grasp the underground gas outburst conditions and changing patterns. Gas inspections refer to the process of measuring and inspecting underground gas outbursts and gas concentration parameters according to the prescribed time and route, and timely discovering and eliminating gas safety hazards. Ensuring the authenticity and reliability of inspection results is the fundamental guarantee for safe production in coal mines. Relevant regulations have made clear provisions and requirements for the system construction, inspection scope, staffing, and inspection frequency of gas inspections. For example, the gas concentration of the mining face of a low-gas mine must be inspected at least twice per shift, and the high-gas mine must be inspected three times per shift. Protruding coal seams must be inspected regularly by dedicated personnel. Therefore, the importance of a true and reliable gas inspection process and measurement results is self-evident.

[0003] At present, gas inspection mainly relies on professional gas inspectors who carry optical gas detectors and measure gas concentration at corresponding measuring points according to the route set before the shift. They fill in the record board manually and archive it, and report the measured data to the ground dispatch room. Since there are many gas concentration measurement points underground and the measurement work is highly repetitive, the authenticity of the measured data during the gas inspection process is greatly affected by human factors, and there are situations such as insufficient inspection, false inspection, and empty shifts, which makes it difficult to ensure the authenticity of the measured data and brings major safety hazards.
